"A cabochon (/ˈkæbəˌʃɒn/, from Middle French caboche "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. Cabochon was the default method of preparing gemstones before gemstone cutting was developed." - (en.wikipedia.org 21.09.2020)
