We carry this "stone" in earrings, pendants, rings and two sizes of bar necklaces. We currently have a few dozen of these. They look similar, but we'll post a couple more of them just for grins. End-to-end length is 18-inches with a polished Sterling chain. It is 1.25-inch wide and 5/8th's-inch tall. Weight is .60-ounces. The Navajo buy this material in a compressed "brick" about the size of a house brick. A whole brick is costly. One of the well-known turquoise mines takes pieces of turquoise, spiney oyster shell and bronze and puts the mixture into a machine that applies huge amounts of pressure which turns these elements into a hardened brick. Hallmarked "DS," which is Donovan Skeets. Always free priority shipping.
