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 Jade” stipulates that: wholly or partly produced or manufactured artificially, used as materials for jewelry and decorations, collectively referred to as artificial gems. 言い換えると, 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: 合成宝石, artificial gems, combined gems and remanufactured gems.
The national standard GB/T 16552 “Names of Jewelry and Jade” stipulates 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. その物理的特性, chemical composition and crystal structure are basically the same as the corresponding natural jewels.
例えば, 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, 屈折率など, density and Hardness etc.
Synthetic gemstones must be named with the word “合成” 対応する天然宝石翡翠の名前の前に, such as synthetic diamonds, synthetic rubies, synthetic crystals, synthetic opals, 等.
