Hi there. I am selling this beautiful, purple, grape agate chalcedony specimen. It's hard to capture in photos but the little purple chalcedony "grapes" are covered with almost microscopic quartz crystals which make it so sparkly! These lovely specimens come from the island of Sulawesi, Indonesia! They are totally and completely fascinating and I loved them from the moment I first saw them. If you have any questions, do not hesitate to ask me. Thanks so much for visiting my listing and have a great day!.
