Cabochon


A cabochon (/ˈkæbəˌʃɒn/), from the Middle French word caboche (meaning "head"), is a gemstone which has been shaped and polished as opposed to faceted. The resulting form is usually a convex (rounded) obverse with a flat reverse.

This shape is used to bring out the incredible cat's eye (chatoyancy) or star effect (asterism) in certain gemstones.
