Vintage Larimar statement ring in Artisan Sterling Silver, Spiral design

This large Larimar is handset onto a solid piece of silver than ornately designed. I’ve had this ring for quite a long time, Barely wore it though, I just loved the stone. I don’t remember the carat weight but the gemstone measures 16 mm x 14 mm… total length 30mm ( about 1 1/4 inch). Shows no signs of wear
