These! Yeah THESE! I have saved these for near 40 years! The extremely rare Isle Royale Zeolite sometimes called Isle Royale Thomsonite by the Old Fisherman who found them. Seldom are they found with complete “eyes” or “patterning”. Here they are joined with another rarity, the Thunder Bay Amethyst bead found just to the North of the island across in Ontario. along with a touch of frosted Black Onyx and copper. Enjoy them as there are no other stones like these. Truly a Borderlands  treasure as well as a North Shore treasure!
