Kingman turquoise can be a sky blue or green color, often with tiny sparkling copper inclusions or matrix and veining. Sleeping Beauty Turquoise: 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. These stones were discovered by accident while miners were pulling copper and gold from the mountain.
