Easy Ways to Start Your Own Mineral Collection!

Are you a fan of relaxing, quiet time, spent in the outdoors? Are you an individualistic person, who enjoys bonding with others with similar interests and building connections?

Collecting minerals involves adventure, a connection with nature, spending time outdoors and then enjoying the collections created by others; hence building some interesting, possibly life-long connections.

Howard Fensterman is a NY lawyer, with a knack for mineral collecting. He has helped scores of collectors build and secure their personal collections and that makes him the perfect advisory for anyone just getting in the habit of mineral collecting.

He also suggests the following concrete steps to get your mineral collection off to a great start.

  • Invest In a “Field Guide”

Get a guide or catalogue that clearly defines the qualities of different mineral specimens along with clear pictures. Learn your way through these books and you will soon be able to recognize and class the minerals.

  • Check Out Museums and Other Collections

Books are great; but there is something immensely engaging about seeing mineral collections in person.

There is something so enthralling about the cuts, colors, lustrous finishes and shapes of an amazing specimen.

Find out if there are any public displays of mineral collections in your city and pay them a visit.

  • Attend Mineral Shows

Hundreds of mineral shows are held across the world each year. Try to get to a few once a year and you’ll love the atmosphere if you are a true mineral connoisseur.

Remember mineral shows aren’t just for buying raw-form minerals, but also precious jewelry and other items. These are also a good place to get an up-close and personal look at some beautiful specimens.

  • Go Field Collecting

True-blue mineral collectors can’t resist the charms of finding and collecting fine mineral specimen all by themselves. Go out in the field, visit an active or inactive stone quarry, or take a walk along a natural rock exposure for example, along a shoreline or in the woods. It’s easier to see the veins and pockets containing traces of minerals. And if you are lucky, you might even be able to prospect some beautiful precious/semi-precious stones for yourself.

How to Identify Fake Gold Nuggets

Interested in investing in Gold? Be careful! It isn’t always easy to tell a gold nugget from a copper nugget that has been polished to shine just like real ones. And then there is Fool’s Gold; this is simply the name given to some naturally occurring minerals such as chalcopyrite, bismutite and iron pyrite that look a lot like unpolished gold to the unsuspecting eye.

But there are some ways of testing the nugget and find out if it really is what the seller says it is i.e. gold! And in case you still can’t figure it out, it is always a good idea to consult with a mineral and precious metals expert to help you make the right decision.

As a connoisseur of the finer things in life, Howard Fensterman has a passion for minerals and metals.

According to the professional lawyer and gemstone authority, Howard Fensterman offers the following few ways of ensuring the authenticity of your gold nuggets.

Real Gold Is Heavy

Gold has a specific gravity of 19.3 g; this simply means that it is 19.3 times heavier than a corresponding volume of water. A nugget made of any other metal will feel a lot lighter than a real gold nugget. So if you have ever handled gold, let your intuition guide you on this one. Or better yet, get a weighing scale!

It Always Looks Amazing

Hold the gold nugget under a lamp. Look at it from various angles, turn it around and examine it properly. The color and lustrous shine of a gold nugget remains uniform, but Fool’s Gold will show variations and get caught out! The uniformity in appearance is the secret to figuring out if you have a real gold nugget or not.

Gold is Tough

Try hammering a nail into the gold nugget. Don’t worry; if it really is gold, you don’t run the risk of damaging it.  Because if it cracks or crumbles away, it’s not gold.

Real gold can’t be broken away that easily, it may best or dent slightly but it sure won’t crumble under a hammer.

Do the Nitric Acid Test

This is the most effective, foolproof test we have to date. Drip just one drop of nitric acid (be careful) on the nugget. If it fizzes into green foam, it isn’t gold but copper instead. On the other hand, if the nugget is entirely unaffected by the nitric acid, the Gold Nugget is good.

The Last Word

As the value of gold continues to increase, so does the temptation for scoring a good deal on gold nuggets. Remember, if it sounds too good to be true, it probably is!

Classifications of Minerals and their Uses

Do you know that according to an estimate, each person living in the United States of America uses around three million pounds of metals, minerals, and rocks for one purpose or another?

While we know that minerals, metals and rocks are important parts of our daily lives, the figures are surprising, right?

Carl Ege from the Utah Geological Survey seemed to know this already. This is why, in his book “What are Minerals Used For?” he said that majority of people are not aware that minerals are important part of our everyday life.

Before we delve into the details of what role minerals play in our daily life and how they are used, let’s first understand what minerals basically are?

The Word Mineral

As we all know, the word ‘mineral’ is used in daily life for referring to two different substances; dietary minerals and elements that are found inside the earth. This article, however, is targeted towards the second type of minerals.

How Do We Define Minerals?

Minerals are natural, homogenous substances that have crystalline structure and are found inside the earth’s crust. In simple words, they can be understood as naturally occurring elements.

The International Mineralogical Association put forward a standard definition of minerals in 1965. According to it, “a mineral is a chemical compound or an element that is formed as a result of various geological processes and features a crystalline structure”.

The above given definition tells us that a naturally occurring substance must fulfill the following criteria in order to be considered as a mineral:

  • It is formed naturally, as a result of various geological processes. There is no such thing as a synthetic mineral. Even gemstones that are prepared in the lab are not considered minerals, for example cubic zirconia.
  • It occurs in solid state. A mineral does not exist in any other state, but solid only.
  • The crystalline structure is another criterion that a substance must fulfill in order to qualify as a mineral. Each type of mineral is formed by unique geometric arrangement of atoms that gives them a different crystal structure.
  • As DNA is the basic structure of human cells that differentiates each person form the other, a mineral is identified by its chemical composition. Each type of mineral features a unique chemical composition that differentiates it from other members of the mineral family.

How Do We Classify Minerals?

Mineral classification is a highly difficult process due to their abundance. A large numbers of minerals i.e. more than 4,600, according to the International Mineralogical Association, have already been discovered while the process of finding more is still going on.

For identification and classification of minerals, following characteristics are taken into account:

  • Color
  • Luster
  • Streak
  • Hardness i.e. its resistance to scratching
  • Density
  • Transparency or Clarity
  • Cleavage and fracture i.e. its breaking pattern; whether it breaks along smooth lines or unevenly.
  • Specific Gravity
  • Crystal structure

Categories of Minerals

Once a mineral is identified by taking into account the above mentioned factors, it is categorized either as a silicate or nonsilicate, according to its chemical composition

  • Silicate Minerals

Silicate Mineral

These are most commonly found minerals; they make up almost 90% of the earth’s crust. Silicate minerals contain oxygen and silicon as basic materials and are usually formed as a result of the natural process of the cooling of melted rocks.

  • Non-silicate Minerals

Non-silicate minerals also make a large group. They are sub-divided as:

  • Oxides
  • Sulfides
  • Sulfates
  • Carbonates
  • Organic Minerals
  • Native Elements

Non-silicate minerals are formed as a result of different natural processes:

  • As a result of the process of mineral decomposition
  • Due to cooling of magma
  • Evaporation of water from earth that leaves behind the crystals of minerals

Ten Commonly Used Minerals

Last August, we discussed the most commonly used minerals and how they are used. Now, we will elaborate on them some more, as well as additonal common elements in the mineral category. Despite the fact that thousands of mineral have so far been discovered, not all of them are being used by human beings. Only 100 minerals are commonly found due to their abundance and as many as 40 have diverse usages in our daily lives.

Here, we are highlighting the ten minerals that we commonly use in everyday life:

  • Aluminum

One of the most abundantly found metallic mineral inside the earth’s crust, Aluminum is widely used in various industries. Its biggest use is in the manufacturing of airplanes and automobiles. Around 25% of aluminum is used is canning and bottling industries, whereas 14% is used for electrical and building purposes.

  • Asbestos

Asbestos is a class of minerals that include six fibrous minerals. They are, actinolite, chrysotile, anthophyllite, amosite, tremolite, and anthophyllite.

We all have heard about asbestos being used for insulation due to its heat resistant property. However, it is also used in manufacturing of cement sheets and pipes, various friction products, paint filler, chemical filters, gaskets, etc.

Although asbestos is dangerous for human health, it is used because the minerals can easily be converted into flexible, strong, and heat resistant, fibers.

  • Beryllium

Beryllium is an important mineral for aircraft and defense industry because it’s light, yet very strong alloys are used in aircrafts manufacturing. The mineral is also used in bronze metallurgy, as a deoxidizer, in fluorescent lights and X-ray tubes. However, Beryllium is a highly toxic mineral.

A widely used precious gemstone emerald also belongs to the category of Beryllium.

  • Copper

Copper is another highly useful mineral that is widely used in a range of industries. From jewelry, electric wires, cables and machinery to plumbing, transportation and in making of currency, copper is abundantly used by humans in manufacturing of products that are used on a daily basis. Since copper is a good conductor of electricity, it is widely used all over the world in electrical industry.

  • Clays

Different types of clay minerals are used in the manufacturing industries. From household products, such as crockery, and pottery, to sanitary products, tiles, firebricks, fire clay and various construction materials, clay minerals play the key role. Additionally, they are used to make certain products that are very commonly used in everyday life, such as paper and rubber.

  • Gold

Gold is one of those minerals that everyone is aware of. Apart from its key usage i.e. to make jewelry, gold is also used for making medals, coins, computer circuitry, for electroplating, for manufacturing certain applications used in aerospace industry, and for various electronic and scientific instruments.

Gold is also used in the field of dentistry for making artificial replacement teeth. Gold is an easily malleable metal that adds value and diversity to its usages.

  • Iron Ore

Manufacturing of steel is the biggest purpose Iron ore is used for. The fourth most abundantly found element in the earth’s crust is also used for making auto parts, magnets, catalysts and numerous other metallurgical products. Modern world largely owes its development (in terms of construction and production) to the Iron ore.

Iron ore makes up the 5% of earth’ crust.

  • Lead

Do you know that the United States is not only the biggest producer, but also the recycler and consumer of lead?

It is mainly used in manufacturing of ammunitions, nuclear shielding, containers, television tubes, ceramics, batteries and in the construction industry. Previously, lead was also used in manufacturing of household utensils, in pencils and paints, but these uses have largely been terminated because of its harmful effects. Upon contact, Lead can poison food and water.

  • Quartz

Quartz is the name that has been given to a family of rocks. Silica (a type of Quartz) is the most abundantly found mineral on earth. In crystal form, it is highly popular as semi-precious gemstones. These include smoky quartz, amethyst, rose quartz and citrine. It is also used for manufacturing of paints, glass, precision instruments, watches, abrasives and silicon semiconductors.

Quartz can generate electricity when mechanical stress is applied thus, it is use to make oscillators, pressure gauges, wave stabilizers and resonators. Also, it is used in making pictographic lenses, prism and heat ray lamps.

The Treasure Hunt

We all have played treasure hunts in our childhood and there are no two views about the fact that we all loved those exciting, adventurous, and rewarding games.

How about playing a treasure hunt to find real gems? 

Put simply, gem hunting is a treasure hunt, but one that is performed at an advanced level, utilizing modern tools and professional techniques.

Most everyone loves to look at these shiny, sparkling stones. But, unfortunately, hunting for minerals isn’t as easy a sport as our childhood treasure hunts were.  

As someone rightly said, it is like playing the geological lottery. If luck is on your side, you may find some precious gems without hunting for days, but if luck isn’t kind to you, you may hunt for days on end. Even if you use the most advanced tools and machinery, you might only end up getting your hands on a few semi-precious gemstones.

So before we get into discussing the details of gem hunting, let us take a look at some basic information regarding these beautiful and colorful minerals of nature.

How Do We Define a Gemstone?

Rose Quartz Healing Gemstone

Even though human beings have been hunting and pursuing gems for thousands of years, we still lack a proper definition of them.

Coming up with an appropriate label has been challenging, not only for laymen but also for lexicographers (linguistic experts who compile the dictionaries).

For the sake of understanding, a gemstone, alternatively known as a gem, mineral, or jewel, can be defined as a piece of rock or any other organic material that is generally formed inside the earth. After cutting and polishing, they are used for adornment, architectural, or decorative purposes, due to their beauty and preciousness.

Do you know that the study of gems, called Gemology, was classified as a science during the 1930s?

What Decides the Value of a Gemstone?

Multiple factors contribute to determining the value of a particular gemstone. These include:

    • It’s a natural occurrence inside the earth. This is why rare gemstones are expensive.
    • Beauty
    • The four C’s i.e. color, carat, cut, and clarity
    • Supply and demand 

While the above-mentioned factors determine the value of these entities, there is no universal measurement or classification system in place for any gemstone except the diamond.

Due to the absence of a uniform classification system, some gems are not considered as precious as diamonds even though they are much rarer than diamonds. Following are some of the highly rare gems:

    • Red beryl
    • Alexandrite
    • Musgravite
    • Painite
    • Poudretteite
    • Jeremejevite
    • Benitoite
    • Grandidierite
    • Tanzanite

Synthetic Gemstones – A Cheaper Alternative

Thanks to the advancements in technology, we now have synthetic gemstones. These are made in a laboratory but mostly contain the same chemical properties as the natural ones. In fact, if you put one synthetic and one natural gemstone next to each other, they will be hard to tell apart.

They make a good option for those who are only concerned about appearance and not the veracity of the mineral. Synthetic gems sometimes may have fewer blemishes than real ones. Not to mention they are much cheaper.

Top Three Gem Hunting Mines

Gorgeous gems like diamonds, rubies, emeralds and sapphires are usually unearthed in places like India, East Africa, Sri Lanka, Australia, and Myanmar. The truth is, there are mines all over the US where amateur mineralogists can go and dig for gems themselves. These following mines are family friendly and some even feature on site gemologists that will analyze your findings.

Crater of Diamonds State Park

Located 120 miles from Little Rock, this 37-acre field found in Murfreesboro, Arkansas, was once a gem creating a volcanic crater. The Crater of Diamonds State Park lets you rent shovels,  buckets, and knee pads for your diamond searching quest. Any shiny gems you find can be appraised on site and are yours to keep. The park’s many visitors have so far found over 30,000 diamonds. Most of them have been small but recently in June 2015, one lucky visitor found an 8.52 karat stone, worth about $1 million. Your chances of finding diamonds here are high, and the park also provides camping sites and is open year round.

Emerald Hollow Mine

The Emerald Hollow Mine is found in Hiddenite, North Carolina. It is the only emerald mine in the US that is open to the public. For a small fee, you can do your own digging here. The mine is open year round and features beautiful scenery. Located on 70 acres, you can not only find emeralds but also sapphire, tourmaline, garnet, topaz, and aquamarine. If you don’t feel like digging, the mine also offers unsifted buckets ranging from $5 to $1,000 that are enriched with gems for you to sift through and find.

Rainbow Ridge Opal Mine

The Rainbow Ridge Opal Mine is found in Virgin Valley, Nevada. The mine is open only May through September and you are expected to bring your own buckets and mining equipment. Digging for opals here is hard work, but it can pay off big time. Opals valued up to $50,000 have been found here. A camping site is found 5 miles away that offers outhouse facilities and a swimming pond. Other than opal, gold has also been found in this mine. The mine offers two digging options. A hefty fee of $600 will allow you to dig through a virgin ground load that has been excavated that morning. A $100 fee will give you access to a tailings load. Tailings are previously mined loads that are a great place for newer diggers to start with lots of material to sift through. Small hand tools for cutting through bigger rocks are available to borrow on site.

New Uranium Minerals Discovered!

 The Atomic Energy Commission (AEC) was established in 1946 in an effort to stockpile uranium. Experts and amateurs used radiation detectors to confirm uranium deposits in Utah and so began the uranium boom. By 1955, 800 mines produced high-grade uranium ore, with Utah alone providing nine million tons of ore. After eight years, the AEC had more than enough reserves and ended their program. Left behind were hundreds of abandoned uranium mines. That didn’t stop air and water from finding its way into the mines and helping create new minerals.

Recently, a graduate student from Notre Dame, Travis Olds, has discovered three new uranium minerals. Olds studied uranyl mineral compounds to learn where these radioactive materials are found and how they change in different environments. Just this past year, Olds found new uranium minerals while exploring the old uranium mines in Utah. Along with a small team that includes scientist Owen Mills and Shawn Carlson, they characterized the new minerals.

Leesite, the first new mineral discovered is like uranium rust, containing uranium and oxide layers as well as potassium. Leesite occurs in tiny, bright yellow stacked blades and radiating needles. It also forms powdery masses that rest against companion minerals, mostly gypsum. Due to its structure and chemistry, it belongs to the schoepite mineral family.

The second discovered mineral, leószilárdite, is a pale yellow carbonate formed through uranium ore interacting with air. It was found in the Markey Mine in Red Canyon. Its bladed crystals are barely visible in hand samples. It was named after Dr. Leo Szilard, a Hungarian-born physicist that worked with uranium and constructed the first neutronic chain reactor.

The last uranium mineral discovered is redcanyonite. It was named after where it was found, in the Blue Lizard Mine in Red Canyon. This ultra rare mineral can only form in organic-rich layers that produce ammonium with access to manganese ions. This rare uranium mineral is not water soluble since it is a sulfate, unlike leószilárdite. Its color ranges from orange to red-orange.

 

 

A Countdown of the Five Strangest Geological Formations

  1. Moeraki Boulders

These unusually large and spherical boulders are found lying along a stretch of Koekohe Beach on the coast in New Zealand. The boulders are concretions made by the cementation of the Paleocene mudstone that was exhumed by coastal erosions. The boulders are estimated to have taken about 5 million years to form. After being analyzed, the boulders were found to be made of mud, fine silt and clay, cemented by calcite.

  1. Giants Causeway

In Northern Ireland, the Giants Causeway is an area of 40,000 interlocking basalt columns. These columns are the result of an ancient volcanic eruption. The tops of the columns form stepping stones that lead from the cliff foot and vanish into the sea. Similar basalt columns are found in Iceland, near the town of Vik. These perfectly hexagonal forms are typically found near sources of water, most commonly along coastlines or near streams and rivers.

  1. Cave of the Crystals

Located a thousand feet under Naica mountain in Chihuahua, Mexico, the Cave of Crystals is a cave connected to the Naica Mine. The main cave contains massive selenite crystals, some of the largest natural crystals ever found. Hydrated sulfate gypsum is believed to have crystallized at a very slow rate over half a million years to form these huge crystals. Currently, only scientists are able to visit the Crystal Cave. Other caves continue to be discovered beneath Naica, including the Queen’s Eye, Candles Cave, Ice Palace, and Cave of Swords.

  1. Chocolate Hills

The Chocolate Hills is a geological formation in Bohol province in the Philippines. There are around 1,700 of these conical karst hills spread over an area of more than 20 square miles. They are covered in green grass that turns brown during the dry season and look like endless rows of chocolate kisses, giving the hills their name. The conical and symmetrical rolling hills are actually grass covered marine limestone.

  1. Salar de Uyuni

Found in southwest Bolivia, Salar de Uyuni Is the world’s largest salt flat at 4,086 square miles. It contains around 10 billion tons of salt. The salt flat is located near the crest of the Andes, at an altitude of 11,995 feet above sea level. The Salar was formed as a result of transformations between several prehistoric lakes about 42,000 years ago. The Salar contains large amounts of sodium, potassium, lithium, magnesium, and borax. Currently, it holds between 50-70% of the world’s lithium reserves.

 

Miners Hopeful After US Lifts Sanctions

Myanmar Map The country of Myanmar produces more than 80 percent of the world’s rubies. North of the city Mandalay is a valley named Mogok that is known as the “land of rubies.” Mogok is where the Sunrise Ruby was found. The gem sold for $30.3 million last year and is one of the so-called “pigeon-blood” stones, known to be one of the most expensive colored gems in the world. Pigeon’s-blood red is considered the most precious hue of all according to the American Gemological Laboratories color rating system.

Every day, thousands of natives in Myanmar barely make a living mining for gems, hoping to one day find the ruby that could change their lives. Production in the Mogok region has skyrocketed since the mid-1990s, when the former junta rulers allowed private companies into the region with their heavy machinery and new mining methods.

In 2003, the United States implemented sanctions that would stop the import of gems from Myanmar. This effort was imposed in an effort to starve the military government of its funds. Miners usually earn about $200 dollars or less a month working in the mines. For decades, the junta military and ex-army chiefs oversaw the mining industry. Even though the Mogok valley is filled with mines, the locals see very little of the profits. Mogok is not only a source of rubies, but also sapphires, spinel, peridot, zircon, topaz, and others. It is also a source of the rare painite gemstones.

In October 2016, the US lifted sanctions that prevented imports of rubies as a result of Myanmar’s shift towards democracy under its new government. Sellers of stones in the region hope that the end of these sanctions will see a surge in American tourists and new business. In the past, high-quality gems such as red rubies and blue sapphires were sent to black markets in Thailand. The gem market in Myanmar is optimistic that with ruby prices going up and US companies entering the market, US dealers will be returning to do business. Chief executive Douglas Hucker from the American Gem Trade Association says that they will only work with “licensed dealers and seek to determine that the gemstones they are buying are sources responsibly.”

To prevent further exploitation of Myanmar’s gemstones, the government implemented a moratorium last July on new mining licenses. Companies will have to meet stricter environmental regulations to get mining permits. US buyers will also have to follow stricter international rules to make sure mines enforce good working conditions. These new efforts will help ensure that profits don’t fuel Myanmar’s conflicts with rebels.

Asteroid Mining : A New Gold Rush

The idea of mining asteroids has been around for over one hundred years. In the late 1800s, this idea first came about, and today it is not just an idea, but a reality. There are currently four different private asteroid mining companies that are actively pursuing this new endeavor, such as Planetary Resources and Deep Space Industries.

All the different types of minerals and metals needed to make electronics such as platinum and gold is quite scarce on Earth. Space, however, is rich in these metals. Platinum is a fantastic conductor, yet it is rare on Earth but very plentiful in space. A typical 100-foot asteroid could contain as much as 50$ billion worth of platinum. Asteroid 433 Eros contains about $3 trillion dollars worth of gold. This amount of gold could devalue the entire market, but one thing is for sure, it will definitely have an economic impact.

Twenty years ago, Shell discovered the first North Sea oil deposit located underneath 5,000 feet of water and 10,000 feet of rock. Shell took a very costly risk to extract the oil using robotics, in a very hostile and distant area. This same technique can be applied to mining asteroids. The technology for mining already exists. There have already been three missions, two from NASA and one from Japan, that used probes to reach asteroids and collect dust from their surface. This is the first step to mining asteroids. Besides the scientific value, these explorations are on the brink of launching an entirely new industry.

There are nearly 10,000 asteroids near Earth that have mineral mining potential. With the need for electronics such as smartphones, computers, and other technologies increasing, the global demand for minerals such as copper, gold and platinum is also increasing. The lure of asteroid mining is powerful. Congress has already passed a bill, the Asteroid Act, that will allow those that mine asteroids to claim their resources as private property.

Investing in Gems

Red Gemstones

Investing in diamonds is more realistic for those who can afford the steep prices of rare quality stones. However, it’s still possible to invest in other types of gemstones, and even certain types of diamonds. If you do your homework and become knowledgeable, you can buy pre-owned gems from flea markets and estate sales that are below current values.

The best way to start investing in gemstones is to seek out wholesale sources instead of paying retail prices. Buying lots instead of single stones will also guarantee a better price. Investing in gems also requires the ability to distinguish between synthetic and natural stones, which sometimes requires the help of a professional jeweler to better identify the stones.

The only gems with excellent resale value are those that are large and high quality. This includes untreated sapphires and rubies, as well as emerald, spinel, aquamarine, demantoids, tourmaline, tsavorite, and alexandrite.

Popularity is also a factor when it comes to market price. While other gem prices might fluctuate, gems such as blue sapphire have always been popular, especially in engagement ring jewelry. Blue sapphires are valued for their vivid color and excellent hardness.

When buying gems as an investment, it is critical to buy the highest quality. Fine gems are distinguished by intense and vivid color, outstanding clarity, and excellent cut. Lower-grade stones such as commercial-grade stones are pretty much worthless since they are poorly cut, lack brilliance and clarity, and are usually of average color.

The diamond market works a lot like the art market, where the price is based on rarity and quality, not quantity. Colorless diamonds that are a minimum of 5 karats with flawless clarity are exceptionally rare, typically less than 1% of the diamond supply, making them also incredibly expensive. For those who can’t afford to pay seven to eight figures for a rare diamond, the best type of diamond to invest in is the naturally colored diamond, also called the fancy color diamond.

While colorless diamonds usually stay the same price or drop in price, fancy color diamonds have historically been appreciated over time. They are also pricy even at lower quality because they are valued by collectors and are always in demand. Antique jewelry sold at estate sales is a great source where you can find these fancy colored diamonds.
