How much is an old ivory plus old coral bracelet? 5

The color of the ivory is too one to be true, and the coral is not recognized

Ivory, according to the current laws and regulations of the People's Republic of China, is a prohibited item for sale. Except for old ivory products before 1956, unless you have a special approval from the Ministry of Agriculture of the People's Republic of China, any form of ivory trading activities is illegal, so there is no market for ivory bracelets to refer to.

Ivory is narrowly defined as the incisor of an African elephant or a male Asian elephant. It is often processed into artwork, jewelry, or jewelry. In addition, it is processed into billiard balls and piano keys, which is a very expensive raw material.

An elephant's molars and tusks were originally the same substance. Molars are special structures that are used to chew. Ivory tusks are elongated, protruding teeth from the lips, from which they evolve and generally act as a defense**.

In order to protect elephants from killing, in 1973, plenipotentiaries from 21 countries were instructed to sign the International Convention on Endangered Species of Wild Fauna and Flora, which strictly restricts ivory**, and China joined the Convention in 1981.

Distinguishing between the authenticity of ivory:

At present, the main imitation ivory products are mostly seen in bone and walrus ivory, plastic, resin, and bone products, and the imitation can be judged from the following points:

1. Ivory pattern: Most of the cross-sections of real ivory have reticulated patterns and herringbone patterns, but there are no bone products or other imitations.

2. Color: The texture of ivory is delicate, the surface is smooth, ivory white and light yellow, and the yellow on the surface becomes darker after a long time, accompanied by the appearance of "finch silk". Bone products or other imitation products have a rough texture, most of them have been bleached, and no matter how flat they are, they will also see "bone eyes".

Ivory takes on an oily white sheen even when bleached, while bone becomes dry when bleached.

3. Feel: Due to the fine texture of ivory, the specific gravity is slightly larger than that of bone products, and it feels good and does not flutter.

4. Workmanship: Bone products will not take a lot of effort to carve, and are generally relatively simple and extensive. Ivory carvings are mostly intricate.

Although they are all ivory, the texture of the leather is much rougher than that of the core, and the texture of the core is delicate and smooth. The yellowing of the tooth skin is very fast during the process.

5. Walrus ivory walrus ivory in the antique world is called "horn", this kind of ivory has a tooth skin and a tooth core, but there is no tooth pattern, the texture is not as smooth and delicate as ivory, and the process of dyeing green is only unique to the Qing Dynasty manufacturing office, and the products made such as cigarette holders, lezi, seals, gourd small mouth covers, blindfolds, air eyes and other small objects.

6. Fake walrus ivory, which is mainly plastic or resin products, has some regular and irregular textures, but there is a clear difference between the feel and texture and the real ivory, and it is not difficult to distinguish.
