1. Color ratio: Color is the primary factor for beautiful jewelry. The color difference between genuine and fake jewelry is obvious. Natural jewelry has a natural color, while synthetic gemstones often have too much color and are not natural enough. The most outstanding feature of natural sapphire is its uneven color, while that of synthetic sapphire is its uniform color; For example, artificial jadeite is often dark green, too green, and the color is unnatural.

2. Clarity: Clarity refers to the transparency and cleanliness of gemstones. Use a magnifying glass with a magnification of 10 times to observe whether the jewelry has cracks, flaws, scratches, etc. Generally, there are few defects in synthetic jewelry, and the interior is clean. It is helpful to identify the authenticity of jewelry through clarity.

3. Look and polish: polish is the process of processing jewelry. The identification of the cutting and polishing quality of jewelry is also helpful to identify the authenticity of jewelry. Because after the natural jewelry is polished, the surface is smooth, the refractive index is strong, and the edges and corners are clean; However, the synthetic gemstones are often rough and round after being polished. Genuine natural products of the same size look more delicate than artificial products, and the cut edges are flush and symmetrical.

4. Card weight method: Card weight method is a method to identify the authenticity of jewelry with the same volume by weighing. For example, gemstones made of synthetic zirconia crystals are similar to diamonds in shape and are the most ideal substitutes for diamonds. It is difficult to distinguish the true from the false diamonds when they are put together. For example, if you weigh diamonds and zircons of the same volume at the same time, the heavy ones are diamonds, and the light ones are zircons. Similarly, according to the pearl school, the most important is natural pearls, and the least important is artificial pearls.

5. Light identification method: put the jewelry you want to buy under a covered table lamp for inspection, put down the lampshade so that the light does not directly penetrate the eyes, and then place the jewelry on the edge of the lampshade, so that half of the jewelry is in the light, half in the dark, and half of the jewelry in the light can be exposed to the internal defects through the light. If the angle of the gem is changed continuously, all its defects can be exposed.

Of course, depending on the situation, the processing of gemstones includes cleaning, bonding and other processes. Only in this way can we finally create exquisite jewelry
