Which type of turquoise is usually more desirable?

Natural turquoise is typically considered more desirable due to its purity and lack of artificial enhancements. It is valued for its unique color, which can range from sky blue to green, and is formed through geological processes without human intervention. The appeal of natural turquoise comes from its rarity and the connection it has to its natural origins, often making it a favored choice among collectors and jewelry makers.

In contrast, stabilized and treated turquoise often undergo processes intended to enhance their durability, color, or appearance. These treatments can compromise the stone's intrinsic value for purists who prefer gemstones in their original state. Raw turquoise, while also valued, may not possess the finish or polish that enhances its visual appeal for jewelry applications, which typically boosts the desirability of finished stones.

Overall, natural turquoise's uniqueness and the story of its formation contribute to its higher demand and value in the market.
