And we humans are always intrigued and fascinated by such characteristics. Therefore, opal comes in an elite category of stones that have always been appreciated and revered the world over.
What is an Opal?
The opal stone is classified as mineraloid, a mineral-like substance that doesn’t possess the characteristics of crystalline structures. Opal is an amorphous form of silica which displays a mix of various colors giving it its enhanced enchantment quality. The colors are borne out of the chemical and physical conditions in which the stone is formed.
Most common opals have green and white hues, while black opals are considered to be the rarest. Let’s look into the history of opal to know how this gemstone has been perceived over time.
Historical Journey of the Opal
The Opal became mainstream with its discovery in South Australia in the 18th century. However, anthropology tells us that opals were in use way before this discovery.
An opal artifact was discovered from a cave in Kenya which dates back to 4000 B.C. According to anthropologists, these artifacts were brought over from Ethiopia.
Apart from that, opal is also depicted in many ancient paintings as a part of ornaments and jewelry. In ancient Europe, Hungary was the origin of opal mining and it is believed that Spanish soldiers introduced this stone to the rest of the world in the 16th century.
The historical significance of opal can also be authenticated by the origin of the name ‘Opal’.
- According to some references, the name opal is derived from a Sanskrit word ‘Upala’ which means ‘precious stone’.
- Many historians associate the word opal with ancient Rome where two languages were dominant, Latin and Greek. A Latin word ‘Opalus’ means ‘precious stone’ is also thought of as the origin of the name, while the Greek word ‘Opallios’ meaning ‘to see a color change’ is also considered to be a strong contender for the origin of the word Opal.
It is quite evident that whichever origin story you want to buy, the characteristics of opal have always been linked to magnificence.
