How do you distinguish between red agate and red coral?

There are always some similar jewels in the jewelry world, such as emeralds and green tourmalines, sapphires and spinels. These gems always make people stupid, and the two gems to be mentioned in the following series are us. It's very common in life, but it's also like a pair of twins, but if you can't tell the difference, it will make a joke.

Once a jeweler friend took out two bracelets and asked me, you know which one is South Red Agate, which is red coral? At that time, I was embarrassed. It was so similar that it was so different that I couldn’t tell each other. I had to tell the truth. The friends laughed and said that they didn’t blame you. They really looked like they were not professional. So I explained the difference between the South Red Agate and the Red Coral.

First, by block degree

Because the shape of the southern red agate is usually irregular, it is larger than the red coral, so it can be processed into larger beads and carvings. Of course, there will be small pieces of South Red, which is just a rule of exclusion.

Second, the gloss distinction

Red coral is an organic gemstone with a glossy luster on the surface or a glossy glass. Nanhong is a jade, the luster is more biased and waxy. Although the South Red Agate of Jiukou and Lianhe also has a glass luster, the nine-neck material is generally of a solid color, and it will have a flame pattern, and the stone is relatively species. The joint material is relatively transparent, even if the highest quality joint material will be slightly transparent, there is a difference between the gemstone gloss and the red coral.

Third, the texture distinction

The texture of the red agate is a typical strip-shaped agate pattern, and the high-quality Nanhong is invisible. Although the texture of red coral is different from the variety, some are visible to the naked eye, some are invisible to the naked eye, but under the magnifying glass, parallel fine texture can be observed, the longitudinal direction is wavy, the cross section has concentric circles and radial texture, generally beads And the ring face is fingerprint-like.

Fourth, hardness distinction

Due to the different composition of the red agate and red coral, the difference in hardness is also obvious. The hardness of the south red agate is about 7 for Mohs, while the red coral has only about 4 Mohs, so it is easy to distinguish the two from the hardness.

Five, the hand difference

Red coral has a similar feel to beeswax and is warmer because it belongs to organic gemstones. Nanhong is jade, and the feel is relatively cool.

Sixth, price differentiation

Because of the low stock, national policy restrictions, and difficulty in fishing, red corals are more expensive than Nanhong. The average price is about five or six hundred, while the average price of Nanhong is about two or three hundred. However, the price of Sardine red coral is similar to that of South Red Agate, and sometimes it is cheaper than South Red Onyx. It is still necessary to distinguish the previous features.
