The Amethyst Druse with Two Generations of Calcite
The amethyst druse on its stand has a most intriguing form, home to several larger calcites. Further younger generations of calcite, which only come into their own in the light and so enchant the whole druse, sit on the larger double-terminated calcites. The amethyst crystals are violet, partly with a grey tone reaching to the agate rim.
