Opal is the world's most popular phenomenal gemstone, with many cultures believing that opals have supernatural origins and power. These Marquise Opal Triplet Cabochons are crafted by bonding a piece of genuine opal to a black agate 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 for use in finished jewelry.
Opal is the birthstone for October, making these cabochons a natural choice for birthstone jewelry designs. Available in three marquise sizes to suit a range of settings and applications.
