RM2242   Roweite and Olshanskyite

Shijiangshan mine, Linxi, Linxi Co., Ulanhad League, Inner Mongolia, China

Rich aggregates of laminar and tabular roweite crystals, with an exceptional quality for the species. The crystals of this rare calcium and manganese borate show very well defined forms, with a light brown color and excellent definition. The quality of these specimens is far superior to that previously known for the species. Along with them, and giving a very aesthetic touch, a group of olshanskyite crystals, a calcium borate, of a snowy white and with parallel growths. There is no doubt that this specimen is very worthy in any mineral collection and display.
