Beryl (Var: Aquamarine)
Medina, Minas Gerais, Southeast Region, Brazil
Miniature, 4.3 x 2.9 x 2.4 cm
A strange-looking crystal of aquamarine in matrix from Medina. It is doubly-terminated (the bottom termination has a bit of edge-wear, but you do not see it anyway), and measures 3.6 cm. What makes it so odd is the silky look, with milky translucency and almost green color. The matrix is a mixture of quartz and muscovite.
