Blue chalcedony and apatite sterling ring size 10

This is a bit of a heavier Ring weighing 10.27 grams and measuring a size 10.

It’s in great pre owned condition needing a bit more polishing than I was able to accomplish.

Blue smaller stones test as blue apatite

Designer hallmark stamp inside I can’t quite decipher yet. Made in Thailand.
