How do you tell the difference between synthetic Australian opals and nautural Australian opals?
To someone not familiar with Australian doublet and triplet opals, it would be difficult to tell the difference between them and solid opals when the stones have been set.Some of the ways to tell the difference are:The price - doublets and triplets are much less expensive than similar solid stones;Doublets have a thin slice of opal mounted on a black backing. If you can see the underside of the stone in the setting, you can tell whether it is a "black backing" or the stone;Triplets have a clear quartz cap on top of the opal in addition to the black backing. With a magnifying glass or incredible eyesight, you can see the thin clear layer on top of the stone.Jewelry with doublet and triplet opals has the same appearance as a solid opal. It's possible to find jewelry with amazingly brilliant colors at a reasonably affordable price when the stone is set as a doublet or triplet.
Where can you find opals?
Opal is mined mainly in the country of Australia. It is also found in Nevada in the United States. You can also find opal at a Natural History Museum or a Rock Shop in your area, a good chance to study a variety in person. The Natural History Museum in Cleveland has an amazing collection. At a rock shop you can touch and feel the opal, so much better than browsing on the internet, which is a good source for information. One of the best rock shops is ROCK STAR CRYSTALS in Manhattan in NYC. They have a large variety of opals to look at, including fire opals, pink and blue andean opal, australian opals, ethiopian opals, honey opal, green opal, and even opal jewelry. Might be worth a visit to NYC just to check them out - and you can be awed by the mineral collection at the NYC Museum of Natural History at the same time!
