One of the more uncommon Beryllium Silicate species, Milarite is a real "mineral collectors" specie. This piece is from the find some decades ago in Guanajuato, Mexico. The Matrix is a mix of Quartz and Valencianite (variety of Adularia). The Valencia Mine is the type locality for the Feldspar and was the source of these small bright yellow Milarites which were big news in the mineral world. This piece has several very small crystal and one a bit larger (about 8mm). These are flat habit and the structure is not as evident without good magnification. A fair example of the find that is not crazy expensive.
