Vintage Sleeping Beauty blue marquise turquoise sterling ring, size 5.75-6.25

🔥Angular styling adds artistic impression to this hand-tooled design. No hallmark, but tests as sterling. You will notice the intricate setting with double diamond design. In addition, the sterling when hot, was manipulated with a hand-tool to make distinctive opening is the shank. I find it stunning and would be keeping it if 1/2 size larger. The piece weighs 5 grams. Sold in as-is condition. No trades. Cheaper in a jewelry bundle.
