Indonesian Purple Chalcedony Agate Cabochon IPCC1. VERY GEMMY lighter purple color with a touch of white on the edge. it is clear enough you can read print through it .. it is a super nice little gemstone. This old gem material was always hard to get and good quality rough stone was/ is expensive but well worth it. It is polished to a very high gloss on the front and sides and the back side too. It measures about 22.1 x 9.5 mm by 4.5 mm thick. I have an American Quarter (25 cents) coin in one of the pictures to help you understand the size.
