A cabochon is a gem with a domed top and either a flat or slightly convex base. Cabochons with convex bases are known as double cabochons. Translucent to opaque gems, often highly-included, are commonly fashioned into cabochons. Several phenomenal gems, such as opals, star sapphires, and cat's eye are cut into cabochons to enhance their phenomena. |
