Description

Old Italian classic. The amethyst crystals show light violet color, sharp termination (some even double-terminated), and very good luster. The freestanding main crystals is completely framed with tiny, orange calcite crystals. This detail makes the specimen really special, I tried to show it on my detail photo. This main group is undamaged. Some of the not so prominet crystals show chipping. Overall a very aesthetic and eye-catching sample. Harder and harder to find now.
