More details

Goldmanite

Is a rare type of garnet hardly seen either as specimen or as cut stone.The formula is Ca3V3+2(SiO4)3  with hardness of 6-7.

Is normally found in dark green and brown-greenish color, here is a rare type with reddish color.It has sold to me as Friedelite ,but after several test including Raman and other different spectroscopy, the conclusion proved that is goldmanite with a minor grossular; as in all garnet is impossible to find a pure type,they are always a solid solution.

However,this material is very interesting and rare. It comes from South Africa,but I don't know the exact location.
