How to tell whether red coral is true or false

The color of red coral is bright red. No matter shallow or deep, it is alive, immortal and not stagnant. Red coral has a bright waxy luster. However, the dyed red coral has no luster and its color stagnates. Dyeing coral is to dye white coral red and other colors with organic dyes. The obvious feature is that the dye in the crack is rich, the external color is dark and the internal color is light.

2. 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!

Step 3 consider

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.

Extended data

The biggest feature of red coral is that it has growth line, but imitation red coral doesn't, so the most important thing to distinguish between true and false red corals is to look at the growth line on the surface. Take cylindrical red coral as an example. The cross section of true red coral presents concentric growth lines, while the imitation cross section is radial lines.

Besides looking at the grain shape of red coral, we can also look at the grain spacing of red coral. The growth line on the surface of real red coral is very delicate and the spacing is very small, generally within 0.5 mm, while the growth line of fake red coral is very thick and the spacing is very wide, generally around 1 mm, even exceeding1mm..
