Tips for distinguishing the authenticity of red coral 1. Look at the texture. Red corals all have longitudinal stripes parallel to the growth direction of corals, and they are closely arranged. In addition, the cross section of red coral has ring patterns similar to tree rings, so we should pay attention to these two textures when we identify them with the naked eye.
Second, look at the color. The color of red coral is bright red, whether it is shallow or deep, it is alive and immortal! And red coral has bright waxy luster, while dyed red coral has no luster and its color stagnates.
Third, listen to the sound. Real corals look delicate, but they make a crisp and tough sound when they collide with each other. Generally, plastic or other imitation corals will not have such a hard and brittle sound. This kind of sound is especially obvious on dendritic corals!
Fourth, weigh the weight. Coral has a good sense of weight. Generally put in the palm of your hand will give people a heavy feeling, which is inconsistent with its delicate feeling. This weight is also one of the bases to distinguish red coral from some inferior counterfeit products!

Red Coral 1 Method of selecting red coral: The first step is to look at the variety.
The main species of red coral are Aka, Sardinia and Momo, which is really important. The price difference of different species of red coral is even about 10 times, and the appreciation space is also different. Judging from the current situation, Aka red coral is the most expensive, and Sardinia and momo have their own strengths. No one can say who is more valuable now, but sometimes high-quality Sardinia and Momo are more expensive than Aka.
Choose red coral: the second step is to look at the color.
In terms of color, other things being equal, the darker the color, the more expensive it is (except angel muscle). Take Aka as an example, the higher the color, the almost price difference 15%-20%.
3 Choose red coral: Step 3, look at the size.
As a natural organic gem, red coral is like a tree in its original state, and its size decreases from the bottom to the top, which makes the price of large-size coral chips several times higher than that of small-size coral chips. Take sardine beads as an example. Other conditions being the same, the price per gram is about 1mm, and the weight is proportional to the size.
4 choose red coral: Step 4 look at the shape.
◆ Yuan branch
The shape of red coral jewelry is also very important. Take Aka as an example. If the same original branches are used as finished products, the lowest yield is round beads. The yield is about within 10%, and the whole bead can be flawless except the white core, and the upper part can be flawless to 30%.
◆ Egg noodles
Then there is the egg noodles (the surface of the egg noodles is flawless, not the whole root). If the inside of the egg noodles is a little thinner, it is oval egg noodles (40% discharge rate) > water drops (50%)& gt；; Follow the pattern 60%
◆ Carved works
Then sculpture. In fact, the yield of sculpture is almost between 40% and 60%. However, Akka's carvings are generally flawed, and they are generally cheaper to sell than ring faces. Of course, good carvings are not cheaper than ring faces at all, and good carvings will be more valuable.
◆ Barrel beads
Then the bucket bead, the discharge rate is about 70%. Finally, the original branch. Therefore, the original branches of Aka are also the cheapest among Aka corals.
Of course, round beads are not necessarily good. At present, the price of Aka round beads is sky-high, and many pendants made of egg noodles and original branches are also very beautiful, with low gram price and very affordable.
Momo and Sardinian red corals are different from Aka in that their materials are more suitable for carving, and the prices of Momo and Sardinian red corals are often more expensive than round beads.
4 Selecting Red Coral: The last step is to look at the degree of flaws.
The degree of defects, natural red coral as a natural gem, there will be some natural defects on it, such as wormholes, white cores, pressure lines, barrel beads, round beads, straight pipes and so on. The fewer flaws, the more valuable.
