Goshenite
Goshenite (gem)
Variety of beryl
Goshenite is a colorless gem variety of beryl.[2] It is called the mother of all gemstones because it can be transformed into other like emerald, morganite, or bixbite. Goshenite is also referred to as the purest form of beryl since there are generally no other elements present in the stone.[3] The gem is used as imitation for diamond or emerald by adding colored foil on it.[4]
