Turquoise is a common gem and jade, some high-quality raw ore turquoise gram price easily over 1,000, but on the market, there are countless imitations of turquoise, and the cost means are endless.
Some daily methods to distinguish the authenticity can be applied to the preliminary identification of turquoise, Xiao A and friends today to share:
1. Look at the color:
The color of natural turquoise is very natural, generally blue, light blue, blue-green, green, yellow-green, light color and other colors, the more copper ions in turquoise, it tends to be blue, when there are more iron ions, it tends to green, and the color is relatively not so uniform, there is a more obvious color difference, and there are usually flaws and spots, no flaws of natural turquoise is rare, if there is ** will also be very expensive. Fake turquoise often exhibits an unnatural sense of uniformity, with little color difference. If your turquoise is very uniform and intense, and there is no color difference in the whole bunch, it is doubtful.
Some merchants will dye turquoise that is not so good to make it look uniform. You can wipe the turquoise with a cloth dipped in ammonia, if it fades, it is fake.
Dyed magnesite is often used in the market to pass off as turquoise, which is very realistic and difficult to identify.
2. Look at the iron line:
Natural turquoise usually has concave iron wires, towards nature, thick and thin, no regularity, and natural beauty;The fake turquoise iron wire is artificially made, usually protruding outward, the thickness of the iron wire is uniform, and the direction is regular and rigid.
3. Look at the luster:
Natural turquoise generally has a waxy luster, a dense texture, and a more delicate one that can show a glass luster. If the turquoise sample has a distinct plastic feel, it may be an imitation turquoise product.
4. Immersion method:
When the turquoise sample is half immersed in water and half is exposed, the natural raw turquoise (turquoise that has not been optimally treated) soaked in water will quickly darken due to water absorption, and there will also be fine small bubbles. Some merchants may brush a layer of wax on the surface of natural turquoise to protect it, and if so, it will not change color when immersed in water. Imitation turquoise, as well as optimized turquoise, will also darken when soaked in water, but it is relatively not very noticeable. The pressed turquoise can also change color in water, because it is made of turquoise powder. Therefore, this method is relatively unreliable due to many influencing factors, and is only for reference and needs to be carefully chosen.
5. Tactile method:
Because turquoise has strong water absorption, it will be slightly sticky to the touch. And those turquoise that has been treated and glued will feel a bit like touching double-sided tape.
Because turquoise has a fragile natural defect, so the quality of turquoise in the process of processing the original stone into a finished product, it is almost inevitable to carry out some technical optimization treatment such as dipping, pouring, waxing, etc., whether the turquoise that has been immersed or injected with glue optimization is considered natural turquoise, has been a topic of debate in the turquoise industry for many years. Therefore, if you pursue the accurate identification of completely natural turquoise, it is indeed not easy for ordinary consumers. If you want to determine the authenticity of the turquoise in your hand, especially for the precious turquoise collection, the most reliable way is to go to an authoritative appraisal agency to test it through some professional instruments.
