How to choose black ice jade

Tips for self-identification of jadeite A, B and C:

1, observe the light and see if there is a faint yellow tone. If there is, it is basically determined as A; If there is no white color, it is basically determined to be B or B+C (for example, except for the green species with white background, the rubber of B goods will turn yellow after a long time). Only A goods are natural jadeite.

2. For bracelets without cracks, knocking with other non-bracelet jade will make a tinkling sound, while the sound of B goods is not so crisp. You can compare it with the confirmed A bracelet. Principle of whitening of B goods: B goods are made by soaking natural jadeite raw materials in strong acid and alkali for several months, and then vacuumizing and injecting glue. This process will make the yellow iron and manganese oxides in natural jade particles react, so the B goods will appear unnatural pallor in the finished product.

3. By carefully observing the color of C goods, we can see that the color is cobweb-like.

4. Glossy: The feeling that white paper is not soaked in water is A goods, and the feeling that white paper is not soaked in water is B goods.

5. There is no structural difference between the places with color and those without color.

First, one of the identification methods of jade bracelets: look. Look at her features, structure and color, and check for defects. Cracks in jade bracelets are easy to see when observing light, but sometimes the stone lines and color diameters in the bracelets are also easy to be regarded as cracks.

Second, the second identification method of jade bracelet: touch. Emerald can transfer heat and dissipate heat quickly, and it will feel cold in a short time if it is attached to the face or placed on the back of the hand. Emerald has a high hardness and a compact and delicate structure. After polishing, it can have a high surface finish, and it feels slippery by hand.

Third, the third method of jade bracelet identification: hey. Jade has a heavy sense of falling because of its high density; Other fakes, such as Ma Laiyu and dushan jade, are lighter.

Fourth, the fourth identification method of jade bracelets: listen. The two bracelets lightly collide and make a crisp "steel" sound, indicating that they are natural jadeite, and the impact sound of jadeite B goods filled with obvious jade is slightly dull. However, it is not necessarily natural jadeites that make a "steel" sound, such as diopside (such as Qinghai jadeite) and amphibole sodium jade (such as Myanmar "Shuimozi" jade).

Verb (abbreviation of verb) Identification of jade bracelet V: Tuo: Jade has a strong water retention ability, that is, a drop of water on the finished jade protrudes higher.

There are two main types of jade ornaments.

(1) jade. That is, other jadeites pretend to be jadeites. There are mainly Thai jadeite and Malaysian jadeite, Nanyang dushan jade, Qinghai jadeite, Miyu, Australian jadeite and Dongling stone. The differences between the jadeite mentioned above and Burmese jadeite are as follows: First, the hardness is low; Second, low density (light weight) and weak luster.

(2) Green glass and green plastic. Most of these substitutes are dull and ugly, and their luster is very weak. The relative density is very light, the hardness is low (it can be carved with nails), and there is no cold feeling.

The so-called gold is valuable, jade is priceless, jade is a kind of jade. There is no fixed standard for price. At present, the price of online stores is higher than that of shopping malls.
