About Opals

Due to the geo-thermal formation of the mine, the opal is formed in layers most of which are common Opal. The common Opal which is white can be found all over the mine. It is the color or fire as some people call it that we seek when looking for a good finished opal stone. There are two typical types of finished opal stones that you will see, an opal solid and an opal triplet.

Opal Solids

The first is an opal solid , which is just as it sounds – solid opal. The color band has to be thick in order to create an opal solid, which is about 1 rock out of 30 that has a nice thick band that would make a nice solid. Due to the common opal being white, the solids tend to be a whitish color and they do not shine as brightly as a darker piece would. The second and more common is the opal triplet.

Opal Triplets

The triplet is what is mainly found in our store and what is seen on our site. The triplet has 3 layers, the bottom layer is black basalt, the middle layer is a very thin piece of opal and the top layer is a quarts cap. The three combinations of these make for an extremely stunning piece. The black back helps to reflect the opals color and makes it radiate its beauty, and the quarts cap helps to magnify it a tad bit but more importantly it helps to protect the opal from damage of everyday use. Quarts is extremely durable, if you had a opal triplet ring on your hand, you could bang it against a hard surface and it would be just fine, and if the cap becomes hazy after years of use, it is extremely easy to rebuff the top surface and turn it to a new clear condition again. The triplet is a perfect combination on beauty.

Opals In Space!!

Idaho is an opal-rich area of the Earth, but Earth is not the only planet opals call “home”. In 2008, opals were discovered on Mars. Because opals need water to form, the presence of opals provided evidence that Mars may have had liquid surface water for billions of years.
