SOLD! This is a nice pendant by Bettty Joe, who has been making this same type of two-piece, combination stones for a long, long time. It has the deeper-water and harder-to-find purple spiney oyster shell, and a colorful Kingman turquoise stone. She rubbed the Sterling into the satiny "old-style" patina. It ships with an 18-inch, solid Sterling silver box chain. Complimentary USPS tracked Priority shipping within the U.S.
