Opal is the world's most popular phenomenal gemstone, with many cultures believing that opals have supernatural origins and power. These Round Opal Triplet Cabochons are created by bonding a piece of 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 a vibrant, eye-catching centerpiece for rings, pendants, and more.
Opal is the birthstone for October, making these cabochons an ideal choice for personalized jewelry creations.
