A striking, very uncommon, two-sided, cabinet specimen from the less well-known San Vicente Mine at Guanajuato, Mexico. One side of the thin, banded, amethyst crust is festooned with very striking, layered, "sandwich style," poker-chip calcite crystals to 1.4 cm. The poker-chip crystals are coated with a druse of secondary calcite, giving them an interesting sugary appearance. The other side is dramatically studded with pretty purple amethyst crystals. This is a very fine and rare combination specimen from this historic locale.
