In short: An overview of the Opal
|Etymology||The term “opal” comes from the Latin word “opalus”, which can be translated as “precious stone” and is derived from the Greek expression “opallios” for “change of color”.|
Where does the name of the jewel come from?
The name “opal” is said to derive from the Latin word “opalus” for “precious stone”. This term in turn descends from the Greek word “opallios”, which can be translated as “change of color” or “to see a change”. So the name is program!
Another derivation from the Greek is “ophtalmios”, which stands for “eye stone”. However, the original source of the name is probably a Sanskrit word: “upala” for “noble stone”.
Did you already know? There is a large number of trade names that refer to the color, the type of color play, inclusions or the origin of the gemstone. Among the most famous are: Black Opal, White Opal, Boulder Opal, Crystal Opal, Matrix Opal, Harlequin and Pinfire Opal. All specimens with color changes are known as “noble opal”.
Where you meet Opals
The jewel is obtained from sedimentary rock, whereby the extraction, selection and purification are largely carried out by hand.
Opals are not so rare in nature – more than 3,000 sites worldwide have been discovered so far. First place is taken by Australia, where around 95 percent of all precious opals come from: Especially in the mining city of Coober Pedy, which is considered the largest source in the world.
Did you already know? Every year numerous adventurers travel to Coober Pedy and hope for their great luck there. For a few hundred dollars you can buy a 50 by 50 meter field and go on an opal search yourself, armed with a shovel. Other Australian towns where you might come across the precious gem are Andamooka, Lightning Ridge, Mintabie, White Cliffs and Queensland.
Opals without color changes are found mainly in Indonesia, New Zealand, Ethiopia, Brazil, Peru, Kazakhstan and Europe. In Germany there are some occurrences near Eibenstock in Saxony and in Styria. And also on Mars you should find large opal areas.
The most impressive find so far? 17,000 carats and a price of 2.5 million Australian dollars characterize the world’s largest opal. Found in 1956 during the Olympic Summer Games in Australia, the stone was given the name “Olympic Australis Opal” according to the place where it was found.
The world’s largest polished opal is the Galaxy Opal – certified by the Guinness Book of World Records in 1992. Found at the Boi Morto Mine in north eastern Brazil in 1976, the stone weighs approximately 3,749 carats.
How is an opal created?
The opal is a mineral of the class of oxides and hydroxides. As one of the few precious stones it belongs to the amorphous minerals, which means that it has no crystal structure. Instead, tiny layers of silicon dioxide form a network interspersed with water.
The typical play of colors – also known as “opalescence” – is created because the spaces between the layers refract the light. Depending on the viewing angle, the color flashes which are characteristic of opals change and create mystical moments.
Characteristics: What makes the opal stone so special?
Opals present themselves in an extremely diverse way – from colorless grey to red and yellow, there are many different variations. A blue-green, glossy play of colors is particularly common, which fascinates every observer.
With a hardness of 5.5 to 6.5 the gem lies in the middle of the table according to Mohs: However, since its water content fluctuates, the hardness is not constant. The transparency is considered opaque, sometimes translucent.
A danger of confusion exists for example with yellow-brown honey opals, which look very similar to amber. Banded opals often resemble jasper in their appearance. Therefore always be attentive when buying!
Which varieties are there?
Opals can be distinguished according to the parent rock on which they are formed and also according to their transparency and body color.
- Boulder Opal: Opaque with enclosed boulders
- Fire opal: orange, red, yellow, green and blue shades, without color change
- Crystal Opal: Transparent, no body color
- Matrix opal: mother rock visible, fine cracks filled with opal
- Black opal: dark or black, opaque to slightly translucent
- White opal: white body color, also called “milk opal”
- Welo-Opal: neon-like colors, versatile patterns
What makes the Opal a popular gemstone for jewelry
With its different colors opal jewelry offers an unbelievable variety of facets – due to this mysterious beauty it casts a spell over every jewelry lover!
Opals do not always have a quality that is sufficient for jewelry. But cut as cabochons, they unfold their play of colors best. Fire opals, on the other hand, do well in a facet cut, because this is how the iridescent color works best.
Opal rings, necklaces and pendants as well as opal earrings are particularly sought after. In combination with a golden setting, the gemstone shines beautifully. So how about a fancy opal engagement ring or wedding band?
