What is the major source for top-color turquoise today?

The major source for top-color turquoise today is naturally occurring turquoise. This mineral, primarily found in arid regions, is often prized for its vivid blue color, which comes from the presence of copper minerals during its formation. Natural turquoise forms over thousands of years through a combination of geological processes that create the right environment, allowing for its unique color and characteristics.

Naturally occurring turquoise is highly valued not only for its aesthetics but also for its rarity compared to other forms. While there are various substitutes and reconstructed forms of turquoise—such as imitation, reconstructed, and marine turquoise—they do not possess the same intrinsic qualities or market value as authentic, naturally formed turquoise. This makes natural turquoise the most sought-after source for consumers and gem enthusiasts looking for high-quality stones.
