One also finds pink, red, brown, yellow, orange, and white on the market. The Yellow Spiny Oyster’s especially rare. In the American Oceans, the Spondylids occur along the North American coasts, as far north as North Carolina, on the Atlantic Coast, and northwestern Mexico, on the Pacific Coast. It develops in waters to South America. The Orange Spiny Oyster occurs in shallow to moderately deep waters, where snorkelers and scuba divers readily harvest them. Purple Spiny Oysters grow in deeper water, making them more difficult to find and harvest. Kingman Turquoise originates in the Mineral Park Mining District near Kingman, Arizona. One of the largest domestic turquoise mines, it is found in a large open pit copper mine in the high desert country.
