Vintage Southwestern Sterling Silver Amber Ring

This ring appears to be artisan made and is unmarked and tests as sterling or higher purity.  It features a dark Amber stone, about 7/8 inch by 1/4 inch wide, in a Southwestern setting.  It measures a ring size 6 3/4 - 7 and the face of the ring measures 1 inch long.  It weighs 5.4 grams and while the silver shows nicks and scratches upon close inspection, it is still in great vintage condition.
