A great gift idea for those that love natural stones. You can add on the earrings made with 20G french hook earwires. Spiny oyster copper turquoise is a stone created using natural turquoise with copper inclusions, and spiny oysters. Spiny oysters are one of the oldest stones used for jewelry making by Native Americans in the Southwest and they are found between the Baja California Peninsula and Mexico. They are still harvested today the same as they were years ago by divers and fish nets. The name sleeping beauty came from the mountain where the turquoise was mined. The mountain resembles a sleeping woman laying on her back with her arms crossed. The stone’s color is a robin's egg blue with little to no matrix or veining. These stones were discovered by accident while miners were pulling copper and gold from the mountain.
