This is a very unusual natural jasper/agate mined in South Africa over 40 years ago. I’m not even sure if this variety has a name. It most closely resembles ocean jasper but is quite different to the Madagascar one. I only obtained one chunk of rough from an old collection and I’ve never seen any more since. It consists of golden yellow and white botryoidal jasper and highly translucent lavender chalcedony. It is cut in a beautiful designer cab with a great polish.
If you’re looking for something rare and unique then this is it! I only have a handful of these.
