Hello @Jiangxi_cn , very welcome, this is how a good community works. Happy you could solve a riddle. It’s a very nice ring. Maybe this is how the mountains look in New Mexico.
Seeing you are from China, do you maybe have knowledge where my apple-green turquoise might have come from?
I believe it might be Yungai Temple Mine turquoise (Cloud Mountain turquoise) but have little knowledge on this. If you want, please comment in the linked topic. Thanks, Jiangxi.
