vintage sterling designer El Tom purple stone native american cuff bracelet

From my personal collection, excellent vintage condition. Sterling silver bracelet set with two rows of purple stones (I don't know what kind of stones--open to help on that one). Scalloped edges. 5 3/4" long, 1 1/4" wide. Hallmarked inside with "El Tom" and "sterling." Weight is 61 grams,/2.15 ounces. I polished it some, but left some patina. Also, any jewelry experts that have any input on my pricing are welcome to weigh in as well.
