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 material is gemmy chrome-green crystals of Muscovite in silver Mica and quartzite matrix. These have been polished all over and cut to stand. This is very rare material from the Great Dyke in Zimbabwe, and we assumed for many years that it was Emerald in matrix. The jury's still out on that. We're still testing more as the beryllium is not picking up on the XRF, but this is parts per thousand, so Chrome Muscovite is where it sits at the moment.\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.
