Vintage Tibetan (?) Pendant

Very interesting piece. Appears hand made; possibly Chinese or Tibetan. A large amulet/pendant inlaid with coral and turquoise (not an expert, but I believe the stones are real). Silver tone double link infinity chain (no clasp). The links even have a textural design. Please zoom the photos to see additional detailing and size. The turquoise stones look a bit rough, coral is solid. I'm sorry I don't have more information, it's very interesting; no marks found. Great statement piece of jewelry.
