Aspects of grape chalcedony:

Botryoidal or grape chalcedony, primarily purple on top, and green and purple on the bottom. Formed of rounded crystals all over the stone, it is a beautiful piece to have in your collection. For the original part, you can find a purple crystal "placed" on the green bunch below, as if it had strayed... A translucent base will be offered with the chalcedony so that you can elevate it if you wish.

Note: Particular care has been taken to best respect the natural colors of the minerals offered to you. The photos are taken in the best conditions, and slightly retouched to get as close as possible to the original stone. However, there may be slight contrasts due to the different screens used and their brightness.
