Identification optimization processing turquoise and counterfeit turquoise

I also paid a lot of tuition fees. I finally got to know the experts from the southwestern mining area of ​​Songshi. I will share the experience with you. Everyone Songshi enthusiasts are also careful about the sellers' "text, language games". Some sellers on the market nowadays, "Shangla, Dip" and "Improved" Songshi, which has greatly disrupted the Songshi market!

The so-called "dyeing, potting (also known as injection molding), artificial rubrite" only shows that there is no such difference in the treatment method, does not mean that its turquoise has not been treated! Where the optimization of the treatment of turquoise is like the B goods of jade, the national gem detection will be marked "handling".

Special mark: traditional old turquoise is generally immersed, although the immersion is traditional crafts, but the national identification standard is set to "dip sap" as "treatment", not classified as "optimized" to help everyone buy turquoise, now " No optimization treatment" Songshi identification common sense list: Anyone who has done all kinds of treatments, identified in the national appraisal department, will be marked on the identification certificate - Songshi (treatment), (treatment) represents the immersion, dipping , glue filling, dyeing, etc.

1, the highest value:

A. The color with the highest value of the general turquoise is blue. The pictographic stone and some patterns and unique colors are also popular.

In the international market, there is a saying that 1 gram of gold is 1 gram of pine, which means that the quality of the "blue porcelain pine" is excellent. That is to say, it is the same price as gold in the international market!

B, the best texture is the luster like porcelain. (In some pinestone mines, the turquoise ore is harder and harder.)

C, pure natural turquoise without any optimization treatment is the most collectible value.

2, the method of optimization processing:

A, because the texture of loose stone is loose, multi-mineral symbiosis, it is easily damaged in processing, and the surface is often uneven after processing. Therefore, in order to improve production, optimized treatment has become a process in the processing process of the manufacturer. Therefore, pure natural turquoise without any optimization treatment is rarely seen in the market.

B, "Immersion" in the optimized processing products is of high value (because the immersion is a traditional process, recognized by many fans, the old turquoise in the antiques is mostly waxed), followed by the "dip" method Optimized (filling method), the worst is filling (filling method) and dyeing. (also using magnesia ore as a rock)

3, the identification method for the optimization process without the identification of the instrument:

A, water measurement method: the general installation of the turquoise is front polished, the reverse is not polished, you can rub the turquoise in the clear water, the untreated water is absorbed immediately, the absorption of the wax and the dipping is slow, irrigation The glue does not absorb at all. Putting the turquoise without any treatment into the water will become darker, and the treated will not change, so the turquoise without any optimization is sensitive to weather changes, it will rain in cloudy days, the color of turquoise will be deep, and the dry sunny days will change. Shallow, also in the same piece of turquoise in the south will be darker than the northern color. The rainy season is deeper than the dry season, and it will be darker than when it is mined.

B. Visual inspection: Surfaces that are not optimized for treatment are often uneven (especially with more patterns) and the optimized surface is very smooth. (Many people like the surface light, there is no flaw, in fact, most of the very smooth, especially the pattern has been treated) No optimization treatment----ceramic luster (inlaid: unpolished surface is ore) , no gloss),

Immersion - waxy luster,

Dip--gel-like luster (especially for inlaid, unpolished, with a clear gel-like luster),

Gluing - hair, the gloss is very poor (inlaid, unpolished that is completely solidified gelatinous luster).

C, different characteristics: After the optimization process is long, it will be more and more ugly, but it will not be broken. Without optimization, the more luster it will be, the brighter and brighter it will be.

Turquoise that has not been optimized: it is expensive, but it is very valuable (this year's price is rising), the gloss is good, and the more it wears, the brighter it is.

The optimized treatment is cheap and not fragile, but the gloss is not good, and the more it is worn, the less luster. In addition to waxing, other optimization methods have not been optimized for value, because the price is cheaper and more suitable for processing into decorations.
