Colorless gemmy double terminated crystal of euclase 2.0 cm in length set on a matrix with crystallized muscovite. In good condition, a choice matrix example for the species.Santana do Encoberto in Minas Gerais, Brazil, is a notable mineral locality associated with granitic pegmatites and related hydrothermal activity that has produced a variety of gem and collector minerals. The geology of the area involves evolved pegmatitic bodies that are enriched in elements such as beryllium and aluminum, creating favorable conditions for the formation of rare minerals. Among these, euclase is especially significant and is found as well formed prismatic crystals, often displaying pale blue to colorless hues with high transparency and vitreous luster. Euclase typically occurs in pockets within the pegmatite, sometimes associated with quartz, feldspar, and mica. The crystals form under conditions of slow cooling and fluid rich environments, allowing for well developed shapes and clarity.
