A superb example of the world-class ilvaite crystals which have been discovered at the now famous Huanggang Mine in Inner Mongolia. Ilvaite is a sorosilicate of iron and calcium. It crystallizes in the monoclinic system in black prismatic crystals and columnar masses. The production of the world's finest crystals of ilvaite from Huanggang was short lived, as the series of pockets yielding specimens of this quality were mined-out in a short 2 to 3 year period. This specimen features several well formed, black ilvaite crystals having moderate luster in intimate association with several quartz crystals. Dimensions (cm): 6 H x 5.2 W x 2.5 D. Location: Huanggang Mine, Inner Mongolia Autonomous Region, China City: State: China Date: HWAC# 53020
