Natural turquoise is mainly sky blue, which is so characteristic that it has become a standard color—natural turquoise. The rest are dark blue, light blue, lake blue, blue-green, apple green, yellow-green, light yellow, and light gray. Our company's raw natural turquoise and raw turquoise stone are divided into blue and green. No matter which color it is, the raw turquoise stones we povide are 100% natural. We have the GIA certificate of natural turquoise, and you can buy it with confidence.
