Facts about Turquoise

Turquoise was among the first gems to be mined. Many historic sites have been depleted but some are still worked to this day. These are all small-scale, often seasonal operations, owing to the limited scope and remoteness of the deposits. Most are worked by hand with little or no mechanization. However, turquoise is often recovered as a byproduct of large-scale copper mining operations.
