Sterling Silver Ring set with Larimar Size 9 1/4

Pre-owned sterling silver ring set with blue larimar. It is a size 9 1/4. The stone has a natural indentation in the surface. I can confirm that it is not a chip from a hit as when inspected under a loupe one can see that the edges are polished by the lapidary artist. Color is a lovely sky blue and there is a bit of black matrix and some light areas that look like clouds. Face measures 3/4" long. Weight: 4.8 grams.
