Hey sisters! I'm your old friend and a seasoned player who has been in the jewelry industry for over ten years. Today, let's talk about a particularly troublesome topic – the identification of genuine and fake turquoise! 💔

To be honest, turquoise has been incredibly popular in recent years, from the antique and cultural play circle to the fashion circle, almost everyone has a piece. But precisely because of its popularity, fakes and enhanced products are emerging endlessly in the market, causing many novices and even some experienced players to fall into traps. Today, I will share all my practical experience accumulated over the years without reservation, hoping to help sisters sharpen their eyes and avoid detours! 👀

💡 Core Knowledge: Unveiling the Deception Methods of Fake Turquoise!

Let's first understand the common types of turquoise "fakes" and "enhanced products" on the market:

  • Dyed Turquoise: This is the most common and easiest to distinguish. It usually uses low-quality white turquoise, magnesite, or other materials, dyed green or blue with chemical dyes. This dyed turquoise often has an overly uniform, vibrant color, lacking the natural transition and texture of natural turquoise. Wiping with a cotton swab dipped in alcohol or acetone may cause color fading! 🚫

* My experience: I once saw a customer who spent thousands of yuan on a string of "high-porcelain blue" bracelets. As a result, after wearing it for less than half a year, the edges of the beads started to turn white, and when wiped, it was found to be dyed. It was heartbreaking! 😭

  • Injected Turquoise (Glued, Impregnated): To improve the hardness, luster, and stability of turquoise, many merchants will inject glue into lower-quality turquoise. This treated turquoise will have a plastic-like sheen on the surface, a dull sound when tapped, and may have a fluorescent reaction under UV light. More advanced "impregnation" treatment allows the glue to penetrate deep into the turquoise, making it even harder to distinguish with the naked eye. 🔍

* My experience: A few years ago, at an exhibition, I saw a piece of "raw high-porcelain" with excellent quality and a very attractive price. At that time, I carefully observed it with a strong flashlight and found subtle traces of glue filling in the internal structure, and the surface luster was a bit "unnaturally bright." I decisively gave up. Later, I heard that most of that batch of goods were impregnated. Luckily, I didn't get greedy! 😅

  • Synthetic Turquoise (Reconstituted Turquoise): This is completely artificially synthesized, and may not contain any natural turquoise mineral components. They are usually made by mixing and pressing turquoise powder, resin, dyes, etc. The characteristics are uniform color, fine texture, no natural texture, and often internal bubbles or swirling structures. When observed with a magnifying glass, an unnatural granular feel will be found. 🔬

* My experience: One time, a friend brought a "turquoise" pendant for me to see, saying he bought it while traveling. I immediately felt something was wrong; the color was too perfect, and there was no iron matrix at all. When I looked with a 10x magnifying glass, sure enough, there were obvious granular structures and a small amount of bubbles inside. This is a typical synthetic product. 🙅‍♀️

  • Imitations: Such as glass, plastic, chalcedony, quartzite, etc., masquerading as turquoise. These imitations usually have significant differences from natural turquoise in terms of weight, hardness, luster, etc. For example, glass will appear too transparent, and plastic will feel light. 💡

* My experience: The simplest method is to weigh it by hand. Natural turquoise has a distinct heavy feel, while plastic imitations are light. In addition, natural turquoise has a Mohs hardness of 5-6. A light scratch with a small knife will not leave obvious marks on natural turquoise (but I do not recommend trying this easily to avoid damaging your treasure).

🌟 Practical Tips: How to Develop a Keen Eye?

  • Look at the color: The color of natural turquoise is varied, from sky blue, lake blue to green, yellowish-green, with varying depths and natural distribution, and a sense of transition. Dyed turquoise often has an overly uniform, dull color. Pay attention to the color at the iron matrix; the natural iron matrix transitions naturally with the turquoise body color, while the color at the iron matrix of dyed turquoise may be unnatural or accumulated.

  • Look at the luster: Natural turquoise, after polishing, exhibits a waxy luster or porcelain luster, warm and restrained. Injected turquoise, on the other hand, will show a plastic-like or glass-like luster, which is relatively "unnaturally bright."

  • Look at the texture and iron matrix: The iron matrix of natural turquoise is its unique "identity card," with natural and smooth texture, varying depths, and a sense of unevenness. Synthetic turquoise usually has no iron matrix or the iron matrix is dull and unnatural. Pay attention to the edges of the iron matrix; natural iron matrix edges are clear and tightly integrated with the body.

  • Weigh by hand: Natural turquoise has a higher density (2.6-2.9 g/cm³) and feels distinctly heavy in hand. Plastic, glass, and other imitations will be much lighter.

  • Listen to the sound: Gently tap two pieces of natural turquoise together, and they will produce a crisp sound. Injected turquoise or synthetic turquoise will have a dull sound.

  • Seek professional appraisal: If you are unsure, or if you are buying high-value turquoise, be sure to send it to an authoritative jewelry appraisal institution for a certificate. This is the safest method! National appraisal institutions include: National Gemstone Testing Center (NGTC), China University of Geosciences Jewelry Testing Center, etc.


💖 Conclusion: My Sincere Words

Turquoise's charm lies in its naturalness, uniqueness, and the accumulation of history. When buying turquoise, in addition to distinguishing between genuine and fake, it is more important to choose what you like and have an affinity for. Don't blindly pursue "high-porcelain high-blue"; what suits you best is the best. Remember, there is no perfect turquoise, only the one that is most suitable for you!
