We we’re very lucky to get access to this old stock sugilite. They were off cuts from a gem cutter who was making cabochons to set in jewelry. Because of this there are odd shapes and areas that are translucent and some that are opaque. With the rise in value of this material these would be worth examination for recutting. 

These pieces are not polished.
