It has been ages since I posted here. So much has happened. I don't think I've ever mentioned that I am now selling Thunder Bay amethyst. I sold a few small jewelry making samples on Ebay and one of my customers said they had gold and copper flecks all through them. I've never seen the flecks but I researched the subject and it's a possiblity. Other metals that might be present are silver, platinum, nickel, chalcopyrite, and bismuth.
