Tourmaline - Cruzeiro Mine, Minas Gerais, Brazil
 ex collection Robert check
 
 Wonderful tourmaline with clearly defined end faces from the Cruzeiro mine in Minas Gerais, Brazil. The 3.5 cm high and 2.9 cm wide crystal has a red color at the base and changes in three zones from light green to moss green towards the top. It shows its intense colors in transmitted light. Rare and interesting collector's piece from the early 1980s.
