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. The reason these 18-inch (polished Sterling chain), 1.5-inch wide and 5/8th's-inch tall bar necklaces haven't been posted on this site prior is because they sell too quick to photo and post them. 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. We call it what the mine owners call it—turquoise, spiney and bronze mix—not a coffee flavor or type of dishware. Hallmarked "DS," which is Donovan Skeets. Always free priority shipping.
