This natural round opal cabochon is an appealing option for custom jewelry and one-of-a-kind pieces. To bring out the opal's signature flashing colors, it is recommended that you set the gemstone over a black or dark-colored layer or that you heavily oxidize your metal. Opal is the birthstone for October.
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 gemstone 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 gemstones tend to be brittle and more fragile than the sedimentary gems.
Please be aware that the colors shown are highlighted with lights to bring the color out. The opal will be white.
