Jose Pinto Mine, Jaguaracu, Minas Gerais, Brazil
Thumbnail, 3.1 x 1.25 x 1.1 cm
This is one of the largest examples of a Brazilian milarite I have come across, and happens to be a particularly fullsized thumbnail specimen. Milarite is a highly coveted, yet rare, hydrated, potassium, calcium, aluminum, beryllium silicate. It is best known from the Alps and Brazil, plus a small 1970s find in Mexico. This specimen features a fine, lustrous and translucent, apple green, milarite crystal. These are about 25 years old, and none of quality have been found since the mid-1980s to my knowledge. I think this is just a superb thumbnail for both the significance of the species. The crystal is also of large size for both the locality and for the species, surpassed only by a few freakish specimens from the Alps perhaps.
