Identifying and Evaluating Turquoise

How to Identify Genuine Turquoise

The realm of gemstones can be a labyrinth of confusion and deception, especially when it comes to distinguishing genuine turquoise from faux variants. With its unique hue that captures the enchanting azure of the sky and the invigorating teal of the sea, it’s no wonder turquoise is a sought-after stone. However, the market is often awash with counterfeits, making accurate identification crucial.

Firstly, it’s important to understand that genuine turquoise possesses an inherent temperature sensitivity, feeling cool to the touch, unlike its synthetic counterparts. When inspecting the color, it’s key to note that authentic turquoise tends to exhibit a slightly mottled or waxy appearance, a direct result of its natural formation process. In contrast, counterfeit turquoise often flaunts an overly glossy or unrealistically uniform hue.

Moreover, genuine turquoise is relatively heavy for its size and showcases a hardness rating of five to six on the Mohs scale. It must also be noted that natural turquoise is porous, readily absorbing oils or pigments, which can eventually cause a change in its color.

The Grading System for Turquoise

The value of turquoise is largely determined by its quality, and therefore, a standardized grading system is employed. This system is divided into three main grades: natural, stabilized, and imitation.

Natural Turquoise: This is the most valuable type of turquoise. It is completely untreated—no fillers, dyes, or enhancements have been added. Its color ranges from blue to green, and it often features a matrix, or veiny patterns caused by the stone’s host rock.

Stabilized Turquoise: This grade refers to real turquoise that has been treated to enhance its color and durability. While still authentic, it is less valuable than its natural counterpart.

Imitation Turquoise: This is artificially created to mimic the appearance of real turquoise. It can be made from resins, plastic, or even dyed rocks. Although visually appealing, it holds no real value in the gemstone market.

To further gauge the quality of turquoise, factors such as color, clarity, cut, and carat weight—the Four Cs—are also considered. As a rule of thumb, the more intense the color—preferably an even medium-blue—the higher the value. Clarity refers to the absence of inclusions or matrix patterns, while the cut should maximize the stone’s beauty. Lastly, larger stones are generally more valuable, given that they are rare.

In conclusion, recognizing genuine turquoise requires an understanding of its inherent properties and the grading system in place. By keeping these critical points in mind, one can navigate the turquoise market with increased confidence and discernment.
