The color of the jade bracelet

Emerald bracelets are rich in colors, such as green, red, purple, gray, yellow and white, among which green is the most precious. According to the depth of green, it is divided into many kinds, such as ruby green, brilliant green and glass green 10. High-quality jadeite is green, rich, transparent, oily and free of impurities. When struck with a hard instrument, the sound is crisp and loud. The common bracelet varieties are seedling green, spinach green, emerald or violet floating flowers. The price of jade bracelets also fluctuates within a certain range. Before buying, you should know the approximate price of the current market. Look before you leap.

The price difference of high-end jade bracelets is more than ten times. The price of jade bracelet is the highest among other jade products, because the production of jade bracelet is the most wasteful of jade materials, and the color is also very important for jade bracelet. The price of a slightly darker jade bracelet will be much lower.

Texture of jade bracelet

The identification of jade bracelets depends on the fineness of jade. The better and more expensive the jade bracelet, the more delicate the jade is, and there is no graininess or other impurities, giving people a round and bright feeling. Jade bracelets with good quality are also expensive. If the quality is good and the price is cheap, be careful that they are fakes. Observed by naked eyes under the light, the texture is delicate, the color is soft and the stone lines are obvious; Slight impact, crisp and pleasant voice; Holding it in your hand has a heavy feeling, which is obviously different from other jade. For example, the imitation jade bracelet similar to quartzite is relatively light, and experienced walkers can tell the authenticity with their hands.

The sound of jade bracelets

When buying jade bracelets, "knocking" is a common method in the identification of jade bracelets. Hanging jade bracelets, tapping natural jade bracelets gently with agate sticks, making a crisp and pleasant sound. Knocking on artificial products makes a deep sound.

Identification of jadeite bracelets a, b and c

Cui is also called jadeite. The color is mainly green, with other colors such as red, yellow and white. The red one is Fei, and the green one is Cui. Its quality depends on the color and the land. The color should be green, the thicker the fresher the better; The floor should be transparent, clean and moist, commonly known as "glass floor". Jade seal with good color and quality is hard to find. It is the king of jade seal and the price is extremely high.

A goods: the raw materials and finished products of jadeite are genuine, and there is no artificial forgery. They are genuine. High-grade jadeite has property, value preservation and investment. It is not only material wealth, but also spiritual wealth. Because this kind of high-grade jadeite products are very rare, less and less. Therefore, many people who do jade trade rarely encounter such products. Its price is rising steadily. Some top jade products, such as bracelets, saddle rings, necklaces and some jade artworks, can cost hundreds of thousands to millions of Hong Kong dollars, or even tens of millions of Hong Kong dollars. Some rich people are crazy about pursuing such a finished product.

Goods B: The raw materials or finished products of middle and low grade jadeites with black and dirty bottom and poor water (transparency) but good green color are treated by physical and chemical methods to remove their dirt, increase their moisture, and make them change from bottom to water to better set off the original green color. This kind of jadeite that has been processed but not artificially colored is called B goods. The physical and chemical treatment of B goods aims at improving the grade of jadeite, but the treatment destroys the structure of jadeite, makes it loose, reduces its quality and changes some optical and physical properties, so it can't be compared with untreated jadeite with much lower price.

Goods C: The treatment method is the same as that of goods B, but the difference is that it is colorless, light green or scattered green. The jadeite products made by artificial coloring are called goods C. The difference between goods B and goods C is that goods B only remove dirt and add water without artificial coloring, while goods C sometimes need artificial coloring besides removing dirt and adding water. Emerald with purified bottom water can be directly colored. (Note: Jade merchants used to call it transparent head. "Bottom" refers to the cleanliness and transparency of the green part and other parts of jadeite. )

Discrimination between jadeite and similar jadeite

Because people's love for jadeite is gradually increasing, the value of jadeite with good color is also rising. Because jade is valuable, criminals take advantage of some people's ignorance of jade, and often pretend to be jade with natural stones or artificial glass with similar appearance, so as to achieve the purpose of profiteering and make some ignorant consumers suffer losses. Therefore, we must know something about some similar jadeite rough stones that may appear in the market. Several common similar stones are introduced as follows:

The difference between nephrite and jadeite

We often hear things like "Hetian jade", "Taiwan jade" and "Canadian jade". And the names of "suet white jade", "jasper", "sapphire" and "jet" belong to the aggregate called "nephrite" in mineralogy. "Nephrite" has never been seen in ancient books in China, and it comes from modern mineralogy. Nephrite is a special aggregate composed of amphibole minerals. Nephrite can be divided into white jade, sapphire, jasper, jet, topaz, sugar jade and other important varieties according to its color. The difference between nephrite and jadeite is as follows:

1. nephrite is relatively uniform in color, including white, dark green and dark green. , no bright green.

2. Nephrite is oily and shiny, and there is no emerald.

3. The proportion of nephrite (3.00) is slightly lower than that of jadeite.

4. The refractive index of nephrite (1.62) is also slightly lower than that of jadeite.

The difference between "Ma Laiyu" and jade

In the 1980s, a kind of green, bright and uniform jade appeared in the jade market, and many people were deceived by beading or ring-face, thinking it was a "rare high-grade jade". What exactly is this jade? This kind of jade is called Malaysian jade (short for Ma Yu, also known as "Malay Cui"), just a name. Malaysian jade is not produced in Malaysia. It is the name of a fake jade brought into Yunnan border by some Indian and Pakistani businessmen in the early days of mainland opening. Ma Laiyu is actually a very fine quartzite dyed green, but it is obviously different from jadeite:

1. With the naked eye, the color of Malaysian jade is too bright and unnatural.

2. The proportion of Malaysian jade is 2.65, which is much smaller than that of jadeite from 3.24 to 3.43.

3. The average refractive index of Malaysian jadeite is 1.55, which is lower than that of jadeite.

4. The color will not turn red under the Charles filter, but the dye can be observed under the ten times lens, that is, the color floats, which is a dyeing phenomenon.

The difference between Australian jade (chrysotile) and jadeite.

1. Australian jadeite is too uniform in color, showing raw apple green, rarely dark green, much like plastic.

2. With a magnifying glass, Australian jadeite can never see emeralds.

3. Australian jadeite with a specific gravity of 2.60 is much lighter than jadeite (3.24 ~ 3.43).

4. The refractive index of Australian jadeite is 1.55, which is lower than that of jadeite.

(4) The difference between Dongling jade and jadeite.

In the jewelry market, there is a kind of translucent beaded beads, the color is medium green (its depth changes) (occasionally carved into ornaments). Because of its green color and low price, it is welcomed by many ladies. What is this beading? Asked the seller, he replied, "This is Dongling jade made in India". Dongling jade, also known as Dongling stone, was first born in India, so it is also called "Indian jade". It is also produced in China and Henan. Some people call it "Miyu", but the correct name should be Ying. The differences between Dongling jade and jadeite are as follows:

1. It can be seen from perspective light that there are parallel green chromite mica flakes in Dongling jade. Seen from the side, a "green line" is often formed. Observing under Charles filter, the green chromite appears red.

2. The proportion of Dongling jade is 2.65, which is much smaller than that of jadeite. You can measure it by hand. 3. The average refractive index of Dongling jade is 1.55, which is lower than that of jadeite.

The difference between water ink (albite jade) and jadeite

In recent years, in the jewelry markets of Kunming, Ruili, Tengchong and some big cities in the mainland, a kind of "ice seed" jade with good water head is transparent or translucent, generally white or grayish white, with few white spots and ribbons, and its distribution is uneven. This kind of jade is called "Shuizizi" in Yunnan, and the one with blue ribbon is called "blue flowers floating in the water". In fact, the main mineral composition of ink is albite, followed by a small amount of pyroxene and amphibole minerals. Simple identification can adopt the following methods:

1. Magnification observation method: The ink is mainly albite, not emerald, and there are mostly white stone brain or cotton.

2. Hand balance method: the specific gravity of water mill (2.57 ~ 2.64) is much smaller than that of jade, and it has obvious light floating feeling compared with jade.

3. Measurement method of refractive index: The refractive index of water mill (1.52 ~ 1.54) is much smaller than that of jadeite.

In a word, by understanding the characteristics of jadeite, we can master the difference between jadeite and similar stones.
