Aspects of grape chalcedony:

A unique piece found in 2022 on the island of Sulawesi in Indonesia, this chalcedony traveled more than 11,000 km for Terrae Minéraux to offer it to you. Discover our superb 52g botryoidal chalcedony encrusted with hundreds of microcrystals in the original shape of a bunch of grapes assembled to form the chalcedony. In terms of color, you will find a lovely purple in the center of the stone surrounded by green quartz microcrystals. The few white spots present have not been identified. To display it wherever you wish, a translucent base will be offered to you with the shipment.
