Newly identified chromium rich mineral in the Mica family, now classified as Emerald Mica (Chrome Muscovite). While not genuine Emeralds, these specimens feature stunning green hues and intricate matrix patterns, making them unique and valuable. This is rare material with gemmy green Chrome Muscovite crystals in silver Mica. It comes from the complex geological region of the Great Dyke in Zimbabwe. We originally thought this material was Emerald in matrix, as that is what it looks like, but we were unable to pick up beryllium on the XRF, as it may only be one part per thousand or a small content.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePRODUCT DESCRIPTION\u003c\/strong\u003e\u003cbr\u003eEmerald Mica, known as Mutokolite, is a chromium-rich Muscovite, a sheet silicate in the Mica group.
