Diamantina, Minas Gerais, Brazil
Diamantina, Brazil is know for producing interesting inclusions in quartz crystals. Typically, these are of clay (brown, muddy looking), chlorite (olive green), or brookite (also brown). Many of the crystals from here sustain large damage with their extraction, so many are carved or polished. This piece is a great example not only due to the fact that the termination are intact and the piece is unpolished, but also because the inclusions cause nice colors of Kelly green, purple, and yellow. The inclusions likely consist of chlorite (green), limonite (yellow), and amphiboles (purples to reds). There are a couple negligible knicks to the secondary crystals which is impressive considering that most of these are thrown into barrels to be carved immediately after extraction.
