Description

This AA-grade natural pear-shaped opal cabochon is an appealing option for custom jewelry and one-of-a-kind pieces. To highlight the opal's signature flashing colors, we recommend that you set the stone over a black or dark-colored layer, or that you heavily oxidize your metal.

Opal is a relatively soft mineral that comprises silicon and water and is characterized by and valued for its display of flashing rainbow colors, referred to as the "play-of-color." There are many different varieties, with stone colors ranging from white or light gray to brown or red to black. While opal may be found in either sedimentary deposits or in volcanic deposits; the volcanic stones tend to be brittle and more fragile than the sedimentary stones.
