Opal is the world's most popular phenomenal gemstone, with many cultures believing that opals have supernatural origins and power. These oval opal triplet cabochons are crafted by bonding genuine opal to a black onyx backing, then capping it with a colorless glass top. This triplet construction enhances the stability and protection of the opal while increasing the contrast of the play-of-color displayed — making each stone more vivid and durable than a bare opal slice alone.
Available in a wide range of oval sizes, these cabochons are well suited for setting in rings, pendants, earrings, and other jewelry applications. Opal is the traditional birthstone for October.
