This is a phenomenal piece of cobaltoan calcite that comes from the Oumlil Mine in Oumlil, a part of the Bou Azzer region in Morocco. It has calcites drusies on the faces of the larger calcite crystals which give it a pretty shimmering effect. Cobaltoan calcite gets its pink color from cobalt. Usually cobalt is a blue color, but when it oxidizes in the calcite it turns a vibrant pink.
This piece measures ~11cm x 6.3cm x 4.8cm
