This looks like green jade. If you like green jade, there is a jug that I think is just gorgeous. I would love this jug in turquoise. Here it is... you might like it (also comes in black jade with silver chain). The chain is 26" which would imply this jug is a decent size and not a small pendant.I wish they would reissue this piece. I have this necklace is gold which I love. They still sell some of these disks, but they're smaller - this one is larger (same size as my larger gold one). I know it was sold in the Hong Kong T&Co market, but I could never track it down in the USA. I hope someday I can find one. I've literally been looking for it for over ten years.
