Hello,
These beads are made of agate and intended to be as Tibetan Luk Mik dZi (goat eye). As you see, shape and color are good and beautiful. But I don't think they are not old as Tibetan dzi beads which are more than one or two thousand years. these beads are more likely modern creations but I can not find any information who made them, where and when. Any info? thank you very much in advance
