d_day 279 Posted August 20, 2019 Based on appearance alone I’m going to say no. My guess based only on your pictures is that it’s a piece of chalcedony. Have you done a hardness test? Know the specific gravity? This info along with better pictures taken in full sun will get us closer to a proper ID. 1 Quote Share this post Link to post Share on other sites
