Six points of how red corals should be identified

The red coral has a good color and luster. Red coral is an organic gemstone that grows in the deep sea 100 to 2,000 meters away from humans. Together with pearls and amber, it is listed as three organic gemstones. It is also listed as one of the seven treasures in the Oriental Buddhist scriptures. It has been regarded as a rich and auspicious object since ancient times. The natural red coral is made up of corals and is extremely slow to grow and non-renewable. Red corals grow only in the three major straits (Taiwan Strait, Japan Strait, and the Baltic Strait) and are restricted by the sea. Red corals are therefore extremely valuable. Ornaments made of red corals are extremely popular with collectors, and fine red corals add value very quickly and are valued by collectors.

The six points of how red corals should be identified:

1. Look at the texture: The red coral has vertical lines parallel to the growth direction of the coral and is arranged more closely. In addition, red corals have ring-like rings that resemble the rings of a tree. When viewing with the naked eye, look at the two textures.

2. Look at color: The color of red coral is a kind of lively red color. No matter whether it is shallow or deep, it is alive, undead, and not stagnant. The red corals have a bright waxy luster, while the dyed red corals have no luster, and their colors are also depressed.

3. Listen to the sound: Real corals seem to be delicate, but they have crisp sounds when colliding with each other. Normally plastic or other counterfeit corals do not have such hard and crisp sounds. This kind of sound is particularly evident in branching corals.

4. Weight: Coral has a good sense of weight, generally placed on the palm of your hand will give people a sense of heavy feelings inconsistent with their delicate, this component is also the identification of red coral and some of the basis of inferior counterfeit goods.

5. Identification of natural corals and stained corals: Staining corals are usually dyed white and red with organic dyes and other colors. The distinguishing feature is that the dye is enriched in the cracks, and the external color depth is light and the interior color is light and uneven. Wipe the cotton swab with a 蘸 ** , cotton will be stained.

6. Identification of natural corals and imitations: Coral imitations are commonly found in stained marble, red glass, red plastic, and “Gilson Coral” made of calcite powder plus dye. These replicas do not have the internal structure of natural red corals, and can be discerned by carefully looking at the lines. Dyed marbles are granular structures. Dyes are enriched in mineral grains. Tests can be answered with **; red glass can be done. Very similar, occasionally see bubbles, from the hardness point of view, the glass is larger than the coral, and can not react with the **.
