This is a super rare gem silica natural ring. It is a mix chalcedony, chrysocolla. It is indosesia's most prized stone.
I was lucky to have 4 of these made from some rough I purchased. I kept one myself and love it..I never take it off. It is very comfortable and durable. I am super active and still it hangs tuff.
