Spiny Oyster Shell and Kingman turquoise bracelet
This sterling silver bracelet has stones from the Kingman mine in Kingman, Arizona. The stones are actually a composite material. Since the miners don't want to waste any scrap of turquoise that they bring up, they will take the little bits left over from cutting regular cabochons, mix them with spiny oyster shell, then pour bronze over them. When the bronze cools, they'll slab it, cab it, and voila! These cabochons are the result! The bracelet itself is eight inches long, but there is a two inch extender chain with a cultured freshwater pearl on the end.
