  1. Jewelry refers to rare, beautiful, and precious natural substances such as diamonds, pearls, red sapphires, and ivory. Jewelry jewelry refers to various decorations made of various valuable gems grinding, carving, inlaid and stringing. Natural jewelry is precious resources. It is durable, rare, and crystal, suitable for decoration and treasure. Natural gemstones have the characteristics of texture, elegant, strong, strong, high hardness, stable chemical properties, strong decoration, and high value. There are two main types of processing and production of jewelry jewelry: one is the "inlaid jewelry" embedded in gold and silver; the other is the "traditional jewelery of jewelry or pearls and pearls and pearls. jewelry". At present, the former jewelry on the market is mainly based on. 1. There are many types of jewelry and jade category. There are several categories of inorganic jewelry in our common inorganic jewelry: 1. Natural jewelry: Natural jewelry is mined from the mines. It is considered to make precious gems that can be made into jewelry and crafts, such as diamonds, sea blue gems, and emeralds. Natural gemstones are extremely rare in nature, so their crafts are highly valuable. 2. Half -gem: Half -gem is an accessory with similar substances instead of and simulated precious gemstones. Such as green semi -transparent stone instead of emerald. Half -gem generally refers to low -grade gemstones, and the hardness is below 7 degrees. 3. Synthetic jewelry: The synthetic jewelry is based on some kind of natural gemstone and uses the same nature as natural gems to artificially manufacture it artificially. Such as synthetic ruby, sapphire, emerald, diamond diamond, etc. 4. Gem: Gem is actually refers to the beautiful artificial lead glass, plastic products and other substances that are beautiful. It is not comparable to the above gems in terms of color, hardness, chemical properties, or values. The gems embellished in jewelry made of copper, lead and other materials we usually see in the market are all impersonal gems made of artificial glass or other materials. Organic jewelry is made from biological evolution, such as pearls, corals, amber, and coal essence. The main component is carbon, hydrogen, oxygen, and is combined according to different proportions. When identifying jewelry, you can do it from the following aspects: 1. The color of the color is the primary factor of the aesthetic jewelry. The color difference between authenticity jewelry is relatively obvious. Natural jewelry is natural. Artificial synthesis gemstones are often excessively modified and not natural. The biggest feature of natural sapphire is uneven color, while synthetic sapphire is uniform in color. Artificial emerald is often thick and green, green is too green, and the color is unnatural. 2. The clarity and clarity refers to the transparency and cleanliness of the gem. Observe the jewelry with 10 times the zoom mirror of 10 times the zone, defects, scratches, etc. Generally, there are fewer defects in synthetic jewelry and clean inside. By clarity, it is conducive to identifying the authenticity of jewelry. 3. Look at the process of processing jewelry. The identification of jewelry cutting and polishing quality also helps identify the authenticity of jewelry. After the natural jewelry is pondering and processing, the surface is relatively smooth, the discount rate is strong, and the edges and corners are stiff; and the artificial synthesis gemstone often has a thick and round lines and corners. The natural genuine natural products of the same size look more exquisite than artificial products, and the edges and corners are flat and symmetrical. 4. The card weight method is a method of identifying authenticity by weighing the same volume of jewelry. For example, the gem that is artificially oxidized, the shape is similar to that of diamonds. It is the most ideal alternative of diamonds. It is difficult to identify the authenticity of the fake diamonds and diamonds. For example, the same volume of the same volume of diamonds and vermiculite are weighed at the same time. Similarly, the pearl school tells the pearl that the serious is natural pearls, and the light is artificially raising beads. 5. Lighting recognition method Put the jewelry you want to buy on a hooded table lamp to check, put down the lampshade so that the light does not directly enter the eyes, and then place the jewelry on the edge of the lampshade. Half of the Ming Dynasty can illuminate its internal defects through light. The perspective of constantly changing gemstones can expose its defects. 6. Hardness recognition is the degree of hardness of each jewelry texture. Internationally, the hardness of jewelry is divided into 10 levels. Talge: Hardness 1st Stone: Hardness 6 Gypsum: Hardness 2 quartz: Hardness 7 square fossil: Hardness 3 Yellow jade: Hardness 8 Yawa: Hardness 4 Jade (Sapphire): Hardness 9 Phosphorus 灰: Hardness 5 diamonds (diamonds): hardness 10 10 The above 10 levels are arranged according to the relative hardness. If there are two jewelry in your hand, it is harder to grind it. If the jewelry is damaged, it is a fake, which is intact. For valuable jewelry with hardness above level 9, such as diamonds, emeralds, and red sapphires, if you have pondered the shape of a diamond, you can use edges and corners to try on the glass. It is a fake. 7. Test thermal heat and slow natural gemstone response to the cold and cold changes in the outside world. In winter, a thick fog can often form a thick fog on the surface of the gemstone, and it can disappear quickly. The above methods of identification can only be roughly distinguished from the authenticity of jewelry. If you need to accurately determine jewelry, you must use precision identification instruments, such as using gemstones, folding meters, heat guidelines, etc. Determination of density, thermal guidance measurement, etc. Jewelry jewelry should be treated differently according to the hardness and characteristics of the material. (1) Materials with high hardness, such as diamonds, emeralds, red and blue jewelry and other jewelry, their structural characteristics are relatively stable and the color is enduring. If the effect is not ideal, the method of washing the cleaning agent solution can be used, that is, first immerse the jewelry in the warm water of a small pot of neutral cleaning agent, brush off the dirt on the back of the jewelry with a brush, and then place the jewelry on the water filter paper. Wash it with warm water, and finally take dry water with a dry cloth. (2) Middle hardness materials, such as the jewelry such as protein stones, garnet, emerald, olives and other jewelry. You can only use a soft bristles to gently wash the stains with a soft bristles, wrap it with water absorption paper or gauze, and sewage. Inhale, use alcohol to add water to the soft cloth and rub the jewelry, and then dry it or air dry in the shade of the shade. (3) Low hardness amber, coral, turquoise and other jewelry with strong water absorption, avoid washing with water, will be cracked by heating, and it is not advisable to contact alcohol, oil, vinegar, etc. necklace. Usually apply velvet cloth to wipe the stains to avoid the surface luster, pay attention to reducing friction. (4) For pearls (natural and artificial beads) that are not abrasion -resistant and weakly resistant to acid and alkali resistance (natural and artificial beads), try to avoid the sun and rain and sweat. People should not bring pearl necklaces when sweating, so as not to make them yellow. After each use, you must clean it with a soft cloth, or wipe some cold cream first, and then wipe it with a soft cloth, so that the effect is better.

  2. Jade is collectively referred to, divided into hard jade and nephrite. And emerald is one of the rough jade, "the king of jade"! The method of identification of jadeite is: first, see color, the color of the color, the color, light, light, the color of the color, the color of the color, and the concentration are scattered; second, the sound, the sound should be crisp and pleasant; The higher the transparency, the thinner the texture of the emerald, the higher the price; Connotation; there are also polishing, it depends on whether it can reflect the oily and gloss of jadeite. Agate is a kind of nephrite, with high transparency, but colorless, so it is also the only one that is allowed to be injected. There are rarely fakes under normal circumstances. Really agate its growth pattern is a tree wheel. If it is fake, there will be round small bubbles in the middle.
