The General Characteristics is:
Jewelry naming also has unspoken rules
What is the difference between the white emerald and natural emeralds and is aquamarine a sapphire? What kind of diamond is the Soviet Union drilling? ... The "ambiguous" designation in the jewelry field often makes many ordinary consumers scratch their heads.
Aquamarine scientific name blue crystal. For aquamarine, many people have the misunderstanding of understanding that aquamarine and sapphire are similar in color, thinking that it is a branch of sapphire. In actual fact, aquamarine and sapphire can only be considered distant relatives, they are all transparent beryl crystals. Aquamarine is a semi-precious stone. The so-called semi-precious stones refer to the natural ores with crystal processing value, such as crystal and agate, in addition to the five internationally recognized diamonds, sapphire, ruby, opal and emerald.
In recent years, many people who travel overseas often buy so-called “natural jewellery†under the guidance of some local tour guides. However, many of them have passed inspections, and many of them are artificial, especially in emeralds. However, the invoices received by consumers often use some very vague names, such as: "Australian Emerald", "CREATED Emerald", "BIRON Emerald", "Blanc Emerald" and so on. According to the general rules of the international jewellery industry, all artificially manufactured emeralds should be clearly labeled as "synthetic emeralds," and natural emeralds can be designated as "emeralds." However, "blurry" labels often make consumers become "big heads."
Similar to the "White Emerald" is also called in the diamond field, this is the "Soviet drill", that is cubic zirconia, was first developed by the former Soviet Union, hence the name. "Soviet drilling" is an artificial compound, but it is close to natural diamonds in terms of dispersion, refractive index, etc. It also has an attractive appearance of "fire". You may also have heard of Magic Stone, Magic Diamond, and Moissanite. In fact, they refer to the same kind of thing, that is, moissanite, which is a product of laboratory cultivation because various physical, chemical and optical effects are closer. Real diamonds. Such names include South African diamonds, Colombian diamonds, Swiss diamonds, Thai diamonds and so on. If it is a natural diamond, it is generally not marked with its origin or it is marked as a natural diamond from South Africa.
In the naming of jewellery, there are four types of trickery worthy of vigilance: First, vague collective, such as the jade, Huang Jing, olivine collectively referred to as "jade" or "jade", but do not specify the actual material of the product; Second, The use of jargon, such as the use of green specter, Sun Stone and other commercial names or "jargon" for product identification, so that consumers can hardly distinguish; Third, deliberately missing, such as 18K gold inlay ring, do not indicate the name of the gemstone , And the price difference between different gemstones is disparity; Fourth, given the place of origin, general jewelry can not be named after the place of production, but the so-called "Southern Pearl", "Black Pearl Tahitian" and so is not uncommon.
For consumers, when they purchase high-end jewelry abroad, they must obtain a certificate of authenticity. Among the information provided by the certificate of qualification, the most important concern is whether the material is natural or artificial, whether it has been optimized or processed.
