This is a very old Celtic design used to represent the maid mother crone aspects that then became the father son and holy ghosts to the Celtic areas. I bought a ton of these a while back from a Indian vendor and they may be Bali made as the bail for them looks like that to me. I had them on consignment at numerous different stores and only have a few left. They are handmade thick silver wired genuine stones and the pendant measures about an inch and a half and the bail another half inch. This one is onyx and would look lovely day or night. The design was made popular recently with a tele series and many think this a triskel but they have squillies instead of endless loops.
