Minas Gerais, Brazil
This is a layer of amethyst crystals on a base of colorless quartz crystals. I suspect that the location label may be wrong, because there is no green crust or agate layer, plus the amethyst does not have the cacoxinite inclusions so common in amethyst geodes from this location. On the other hand, Minas Gerais is a huge region, and I am certain that there are multiple amethyst producing areas. These amethyst crystals are relatively stubby, and are organized in parallel clusters with the larger crystals appearing to have multiple faces. Also, fairly strong color zoning is apparent, with the overall color being rather delicate.
