What is the main function of coral stone

Everyone knows that there are corals in the ocean. This is a kind of animal. The corals in the ocean will secrete calcareous skeletons. These calcareous skeletons are connected to each other to form branch-like stones, which are often called coral stones. Many people think that coral stones are a kind of underwater plant, but it is not. It is essentially a stone with a very tough texture. The reason why coral stones are very popular is mainly because they have the following functions.

First, what are the effects and functions of coral stone?

There are many types of coral stones, including red coral, black coral, blue coral, Mediterranean coral, Japanese coral, Cameroon coral, China Hainan coral, etc. Among them, red coral is one of the most precious varieties. Tibetan Buddhism believes that red coral is the incarnation of Tathagata Buddha, and often uses coral as a lucky charm for worshiping Buddha, making Buddhist beads or decorating statues. The Tibetan people believe that red coral has the ability to create a connection with Buddha, prevent disasters, and increase wisdom. They will spare no expense to purchase all kinds of precious red coral ornaments to wear on their bodies, and they also often use it as a form of family wealth accumulation.

The coral is beautiful, blending the calmness of the sea with the heat of fire. People who like coral are beautiful. Beauty lies in the transcendent feeling and taste in their hearts. The state of unity of heaven, man and beauty created by coral and the people who wear coral is the most beautiful.

Second, types

There are many kinds of corals, and they are colorful. Some are like round balls; some are like chrysanthemums in the frost; some look like cedars; some are shaped like deer antlers; and some are like branches. Some corals are very fragile, with branches and stumps broken at a corner, while others are hard in texture. Because of its beautiful color and elegant posture, coral has been used not only to embellish people's study rooms and studios, but also carved into various jewelry products, and is deeply cherished by people.

Third, purchase points

First, the color must be uniform. Second, the color must be bright red. The redder it is, the more precious it is. Third, the specific gravity must be high. The heavier the better.

Coral is rarely confused with other gem materials because its unique appearance, structure and shape make it easy to identify. The appearance of coral is completely different from that of shell pearls, which are of a more or less similar color. The luster of shell pearls has a certain directionality, and when magnified at low powers, it displays a pattern that looks very much like flames. White beads cut from pearl shells to imitate white coral can be identified by the parallel growth structure on the shells and their pink zoning trend. Other identifying features of corals are small, shallow, circular pits, which are where the individual coral polyps grow. Small pits caused by certain perforating marine organisms may also be present.

The main substitutes for imitating coral are celluloid, wood and sealing wax, none of which has the unique appearance of coral. Celluloid emits a camphorous smell when heated, wood can be scratched with a fingernail to expose the wooden structure beneath the artificial surface, and sealing wax appears fluid and glassy under a magnifying glass. If necessary, hydrochloric acid can be used to identify these substitutes, as none of them will react with hydrochloric acid. Conversely, corals, oyster pearls and oyster pearl shells all react with hydrochloric acid.
