RM1727   Elbaite

Morro Redondo mine, Coronel Murta, Araçuaí, Minas Gerais, Brazil

One of a very few tourmalines I found in this old collection with this classic combination from the 1960s or 1970s: nice brilliant lustre, glassy surface, intense color zoning between pink to green. Parallel groth, terminal rhombohedrons and a crossing prismatic pink small crystal between them. This well-known pegmatite mine was discovered in 1991 and produced very colorful tourmalines. Nice gem.
