An old-time, classic calcite specimen from St. Andreasberg, Germany. This fine, three dimensional cabinet piece is interestingly zoned. One half of the piece features more isolated, freestanding, gray translucent, nail-head calcite rhombs, while the other half consists of tightly intergrown, colorless, nail-head calcite crystals on massive calcite matrix. The crystals are very nicely striated on both sides. Old material, dating to the 1800s.
