Wholesale Coral Jade Crystals

Coral jade and silicified wood are formed similarly. Ancient tubular corals were buried deep in the ground after volcanic eruptions. 

After hundreds of millions of years of high-temperature and high-pressure rolling in the ground, they gradually silicified to form chalcedony coral fossils with their shape and texture. It was wholly preserved and later rose to the surface due to changes in the crust.

Indonesia’s Sumatra Island is the main mining area for coral jade. Hundreds of mines on the island are continuously being developed and excavated. 

However, due to the expansion of market demand, the non-renewability of organic fossils and the difficulty in finding high-quality mining areas, the price of raw coral jade is gradually rising. 

The yield ratio of different mining areas is very different. The coral frog holes, small sand holes with incomplete silicification, small geodes and cracks in the coral jade ore all affect the material of the bracelet or pendant. In addition, the coral jade hand pays attention to the appearance of the flower. 

Most of the raw ore is cauliflower radial, so it is exceptionally consumable when slicing, and the production cost and difficulty are high. Therefore, there is still a particular risk in making coral jade bracelets.

Coral jade is divided into mountain material, water material and half mountain and half water material. The water material is more delicate and high-quality than the mountain material due to washing and refining, and the degree of silicification is higher, but it has the disadvantages of relatively inconspicuous flower-shaped layers, easy deformation due to extrusion, and many cracks in the raw materials. 

The brown color reduces the collection value of coral jade. The flower shape of the mountain material is complete and the color is distinct. Still, sometimes the texture is too dry due to insufficient silicification, the calcified skin is too thick or the ore center is not silicified, forming huge pores and reducing the yield. 

Half mountain and half water materials have the advantages of the first two, and it is easy to form high-quality coral jade.

The variability of coral jade will also occur in the same raw ore, especially the water material, which will produce different flower shapes, colors, and textures. 

There is a lot of knowledge on how to observe the success rate of the bracelet in the window skin color and growth form of the original ore.

It is difficult to complete a coral jade bracelet with perfect color, texture and flower shape. There are three main points to choose the top coral jade: shape: different varieties of ancient coral, its pattern, size and density distribution are hundreds different. 

The flower shape is clear and complete without deformation, and the background color contrast is obviously the best. Among them, the most beautiful pattern is called “Margarita Chrysanthemum” in the industry, and there are hundreds of other patterns, such as fireworks, sunflowers, and pine grains.

Color: In the process of silicification, coral jade can produce changeable colors in a bracelet due to the color of the surrounding trace elements. The most common color is light coffee to dark coffee, and there are also colors such as white as suet and black as jade. 

Among them, red coral jade is the most popular in the market. Other rare ones such as pink, orange, green, and even dreamy purple and blue are also sought after by collectors because of their rarity.

Quality: The higher the degree of silicification, the more delicate and transparent the texture is. This is the last point for selecting high-quality coral jade. Some coral jade is completely silicified, but the pattern is not obvious, and its value will be affected. 

However, after wearing it, due to the body’s body temperature and the moisturizing of oil, its lines will become more obvious, resulting in different flavours.

To distinguish coral jade from coral fossils, you can use a knife to scribe. Generally, coral jade with complete silicification will not be scratched. if the silicification is incomplete, it will be scratched.

 If you drop a small drop of hydrochloric acid on the coral jade, there will be no reaction, but if you drop it on the coral fossil, it will bubble.
