Jóias de ouro brasileiras define o que é uma pedra preciosa artificial

The jewellery ordered and sold by Baolong.com is all natural gemstones. And there are some cheap jewelry on the market that use artificial gems. The editor of Baolong.com shares such information to help everyone understand and distinguish:

Artificial gemstones are relative to natural gemstones. They are produced and developed to alleviate the contradiction between supply and demand of natural gemstones. They are artificial gemstones rather than natural gemstones.

The national standard GB/T 16552 “Names of Jewelry and Jadestipulates that: wholly or partly produced or manufactured artificially, used as materials for jewelry and decorations, collectively referred to as artificial gems. In other words, artificial gemstones refer to the materials used as jewelry and decorations that people use the basic principles and methods of modern science and technology, select appropriate raw materials, and use reasonable processes and technical procedures to make them in laboratories or factories.

Artificial gems include four categories: synthetic gems, artificial gems, combined gems and remanufactured gems.

The national standard GB/T 16552 “Names of Jewelry and Jadestipulates their definition and naming method, as follows:

(1) Synthetic gems

A crystalline or amorphous body that is wholly or partly manufactured artificially and has a known counterpart in nature. Its physical properties, chemical composition and crystal structure are basically the same as the corresponding natural jewels.

Por exemplo, synthetic ruby ​​and natural red stone are both alumina (AL2O3) [both contain trace element chromium (Cr)], they have the same crystal structure, and their physical and chemical properties are basically the same, such as refractive index, density and Hardness etc.

Synthetic gemstones must be named with the word “sintético” before the name of the corresponding natural jewellery jade, such as synthetic diamonds, synthetic rubies, synthetic crystals, synthetic opals, etc..
