Calcite on Danburite Calcite on Danburite Calcite on Danburite Calcite on Danburite

Cluster of 3 Danburite crystals, longest 8cm, partially coated with Calcite crystals. For my tastes, this is as nice a Danburite specimen I've seen in this size. The crystals are glassy and transparent, undamaged, with all the top ends uncoated by the Calcite. The Calcite crystals reach 8mm in size, have an interesting form, and are present on both front and back. This is from an old collection and reflects the good taste of the collector.
