Vintage handmade sterling silver ring. It is set with a hand carved frog fetish stone of gorgeous chrysocolla. Stone is turquoise with dark matrix that has some red coloration. Stunning stone! Frog is hald in place by long hand place prongs. Frong has some chipping on nose. 

Size 5.5, Hallmarke dsterling 925 inside and the font tells me that this was made in Mexico at least 50 years  ago if not more.

Frog is 18mm long. Weight: 7.7 grams. Silver has a lovely gunmetal patina.
