Unusual Sterling Silver and Turquoise Inlay Ring Size 8

This is an unusual silver silver and turquoise inlay ring. The tear drop inlay is 15/16" tall x 11/16" wide. The turquoise has nice matrix. What is unusual is the silver was cut and turned back towards the stone. The background is oxidized so triangles of shiny silver surround the stone. I have not seen this style before. The face of the ring is 1 3/16" tall x 1" wide. The shank is 1/8"wide. The ring is stamped Sterling NW. This is a new ring in good conditon. Thank you for looking.
