When buying Tibetan silver jewelry, we should carefully identify it from the angles of color, appearance, inlay and workmanship. Due to the manufacturing process, the real Tibetan silver will turn black when wiped by hand, which is a kind of carbon black and non-metallic black. In addition, the imitations of Tibetan silver are generally made of alloys such as waste lead and tin, and the surface is plated with color, which looks pale and has no metallic luster and metallic texture, while the real Tibetan silver is not very shiny, but it is very textured and has the effect of silver products.
After seeing the color, it depends on the appearance and workmanship of the jewelry. Pure Tibetan silver jewelry has clear patterns, and the patterns on it are all carved by craftsmen, while the patterns on the imitations are very vague. In addition, when choosing, you can look at the place where there is no pattern on the back of the jewelry. Most imitations have obvious marks of machine pressing, which seem to be one by one. The real Tibetan jewelry has a smooth surface and has been polished by hand.
The mosaic technology of Tibetan ornaments is superb. Red coral, agate and other things are often embedded in Tibetan silver jewelry as decoration, while counterfeit Tibetan silver jewelry is mostly replaced by plastic because of cost reasons. Plastic inlays look very beautiful and have bright colors, while the turquoise and red coral inlays in real Tibetan ornaments are much more primitive and rough, which is also one of the characteristics of Tibetan ornaments.
How important is the color of diamonds?
When buying a diamond ring, the color of the diamond is an intuitive aspect of the diamond 4c. Because of its intuition, it is more important. So how important is the color of a diamond when buying a diamond ring?
First of all, let's look at the diamond color grading standard:
Class d: completely colorless. The highest color level is very rare.
Class e: colorless class. Only jewelry experts can find subtle color traces. It belongs to rare diamonds.
Class f: colorless class. Only expert jewelers can detect subtle colors, but they can still be regarded as "colorless". It belongs to high quality diamonds.
G-H grade: close to colorless grade. Compared with higher-grade diamonds, you can see the color, but the price is extremely high.
I-J grade: close to colorless grade. The color is slightly visible. Excellent cost performance.
K-M level: color visual level.
N-Z level: color visual level.
When buying diamonds, color is the most important diamond quality besides cutting. When you see a diamond, the first thing the human eye notices is the cut of the diamond, and then the color. When you consider buying larger diamonds, color is particularly important, because the more light reflected by a large diamond, the easier it is to be noticed. In addition, stepped diamond shapes, such as "cushion" and "radiant", emit less light, which will make them have the function of adding color compared with other diamonds with more facets.
How to choose the most cost-effective diamond ring color?
Generally speaking, I-class and J-class diamonds are slightly visible in color, but they are more cost-effective, especially "round" or "princess square" diamonds. These shapes of diamonds have more facets and can reflect more light, so they can mask the color of the diamond itself.
Both are "colorless" diamonds. What's the difference between D, E and F diamonds?
Comparing the chromatic aberration from D to J, the colored diamond of D is completely colorless and the rarest and most precious. With the naked eye, Grade E and Grade F are also colorless, and only jewelry experts can perceive the color of such diamonds.
How to buy sapphire jewelry
1. It is best to buy sapphire jewelry with no cracks or few defects.
2. It is best to observe the color of sapphire with naked eyes under white light.
3. From the perspective of value preservation, purplish indigo is the most precious.
4. Sapphire will be more or less dichromatic, ribbon or uneven color. When buying, it is best not to choose those with too obvious dichroism, too many ribbons or obvious ones.

There are four points to pay attention to when buying gold jewelry.
In addition to buying gold jewelry in big stores that guarantee quality, we should also pay attention to the following four points:
1. There should be a formal tax invoice indicating the name, color and weight of the jewelry. For future enquiries;
2. Choose according to everyone's age, temperament, body shape and purchasing motivation. At present, the jewelry sold in shops is mostly jewelry from Shenzhen and Guangzhou, which is characterized by novel style and elegant appearance, but the purity is not necessarily high; There are also ornaments made in Zhejiang, which are more traditional in style, but have higher gold content;
3. Carefully check whether the jewelry has burrs, whether the chain is straight, and whether the buckles, connectors and ear clips are safe. In order to make the buckle of bracelet, the joint of earring and the ear head more firm, the color of these parts should be lower;
Jewelry sometimes turns white when worn. This is because when jewelry comes into contact with cosmetics, shampoo, detergent or mousse, chemical reactions will occur, so it should also be less in contact with cosmetics when worn. Once it happens, you can ask the store to solve it with the invoice. When storing jewelry at ordinary times, it is best to pack each piece of jewelry separately with soft cloth to avoid losses caused by mutual friction.
Matters needing attention in purchasing sapphire
Sapphire, with its crystal-clear and beautiful color, was covered with mysterious and supernatural colors by the ancients and regarded as an auspicious thing. As early as ancient Egypt, ancient Greece, Rome and Nordic countries, it was used to decorate mosques, churches and monasteries, and was carried around as a tribute for religious ceremonies. Together with diamonds and pearls, it has also become an indispensable ornament on the crowns and dresses of the kings of the British Empire and the czars of Russia. Sapphire has been one of the top five gems in the world for hundreds of years since it entered people's society, and it is a precious gem.
The following are some precautions when purchasing sapphires.
First, when choosing sapphire, we must first pay attention to the color. Generally, the most ideal blue sapphires are purple blue and pure bright blue. High-quality' sapphire' should be thick and velvet-like, that is, Kashmir sapphire. If the color is too dark or too light, the value will be much lower. Sapphire is particularly rich in color, and golden sapphire is a very precious gem, called golden sapphire, with medium tone as the best. When golden yellow and blue are intertwined, they form a kind of mandarin duck gem, which symbolizes the harmony of feelings and the happiness of marriage. As tokens of love, they are deeply loved by lovers.
Second, high-quality sapphire gives people a sense of transparency. Even people who are not very transparent can see the bright blue light reflected from the depths of the gem under the light. When you turn the gem, you can see the moving blue light, which makes people feel the enjoyment of beauty.
Third, the high-quality blue gem ring will shine, just as it is composed of many small mirrors, and it is just like a mirror just taken out of the water, with a layer of crystal water mist on its surface.
Fourth, the high-quality sapphire should not see defects under the magnifying glass with the letter 10, and be careful not to have cracks.
Fifth, high-quality sapphires should have no obvious color bands. Natural undiluted sapphires are often obvious, so don't pay too much attention.
Sixth, when choosing the ring surface, we should pay attention to its cutting, because good grinding will make the gem look more beautiful.

Pay attention to the following points when buying crystals:
1. Basically, natural and clear crystals are high-grade goods, but the price is high and the quantity is small. Beginners should try not to touch it until they have accumulated enough experience. You can buy some crystals with ice cracks, clouds and inclusions, because these crystals are not easy to synthesize artificially.
2. It should be noted that pure and transparent crystals are easy to be artificially synthesized, and the bigger they are, the easier it is to make fakes; If you look at the crystal contents with a high magnification magnifying glass, if there are bubbles, it may also be an artificial crystal.
3. Transparent white crystals, amethyst and topaz are mostly cultivated crystals, especially necklaces engraved with Buddha statues and scriptures. Pay special attention when buying.
4. Hair crystals, all kinds of phantom crystals, crystal columns, crystal flowers, crystal caves, crystal clusters, raw ore and synthetic products are few, so you can buy them with confidence. When buying crystal caves, crystal strings and raw ore, we should still pay attention to whether they have been repaired, especially crystal caves, which often have traces of repair. It is not difficult to see.
5. When buying powder crystal, if the powder crystal color is too bright and uniform, it is very likely to be dyed, and powder crystal dyeing is very common.
When he held it, the crystal felt very cold. If it is synthetic or acrylic or glass, it feels warm when he holds it.
7. If your hand pulse is unobstructed, you'd better use the method of sensing energy directly. Although everything has energy, but the energy of crystal stone ore is more powerful, you can know it in your hand. Note: the price of crystal is not very high either. If it is not natural, it means the price is high. Swarovski is an artificial crystal, not natural.
