Now there are more and more imitation ornaments on the market, and they are becoming more and more exquisite. Some can even confuse the real with the fake, and the price is much cheaper than the real one. Therefore, imitation jewelry is favored by Amy.

Then, let's talk about the true meaning of 18KGP, 23KGP, 925:

18KGP and 23KGP are the symbols of alloy imitation jewelry.

They are composed of two symbols, 18K or 23K is a symbol, and k stands for gold content, that is, gold content. The relationship between k number and gold content is: Au wt% = K/24 × 100%, and the national standard GB 1 1887-89 stipulates that the gold content per k is 4.

GP is the abbreviation of English goldplain, commonly known as forging gold in business. This logo means that the product is mainly made of phosphorus and copper in general metals after high-temperature forging, and then plated with a layer of gold, which can be divided into two types according to the thickness of the gold layer. The thickness of gold-plated layer is about 1mi (mic is the unit of gold-plated layer thickness stipulated by international standards), and the gold-plated layer is about 3mi.

Simply put, GP is the symbol of gold-plated or gold-plated jewelry, and the front 18K or 23K refers to the gold content of the gold-plated layer outside it. Some people may ask at this point, but most of the jewelry of 18KGP and 23KGP is white instead of yellow. This is the confusion between pure gold and k gold. One of the characteristics of pure gold is softness, so it is easy to fall off when inlaid with gems because of insufficient strength. Therefore, people add silver, copper, zinc and other metals to gold to increase its strength and toughness. The gold ornaments made in this way are also called K gold. In jewelry inlaying, almost all gems are inlaid with K gold with different K numbers. This not only achieves the nobility of gold, but also makes up for its shortcomings, and can be made into various colors as needed. K-gold jewelry popular in the world has various colors, and the common ones are yellow and white. K gold is divided into colored gold alloy and platinum alloy according to color. Au-Ag-Cu(-Zn) alloy is the most commonly used colored gold alloy in ornaments. Platinum alloys are mostly Au-Ag-Ni(Cu, Zn) and Au-Ag-Pd(-Zn, Cu) alloys. Gold mixed with 25% palladium or nickel and zinc. , will turn white, its main component is gold. This name is platinum, commonly known as K gold. (Note that platinum and platinum are not the same concept. Many profiteers play word games to deceive consumers, and some take advantage of people's misunderstanding and lie that platinum is the common name of platinum. )

18KGP refers to gold-plated or gold-plated jewelry with a gold-plated layer of 18K gold;

23KGP refers to gold-plated or gold-plated jewelry with a gold-plated layer of 23K gold.

925 or silver 925, S925 is a symbol of silver ornaments.

Silver has the lowest price among precious metals, which is one tenth of that of gold. In jewelry design, there is almost no need to consider its cost factor. Many avant-garde, exaggerated, luxurious and heavy jewelry can be designed and produced at a lower cost. Therefore, silver ornaments have become another new force in the imitation jewelry family.

Silver can be divided into foot silver and tattoo silver:

Foot silver is said to have a silver content of not less than 990. Because it is too soft, it is not easy to cast into the desired jewelry shape, and it is easy to wear and oxidize and blacken. So it is not suitable for jewelry.

It is said that the silver content of serine is not less than 925 per thousand. Granular silver, also known as "925 silver", is usually made up of 92.5% silver and 7.5% copper. Due to the addition of copper, polished products are brighter and more beautiful than silver, so they are often used as jewelry materials and silverware. This is also a common raw material for silver ornaments on the market. 925 silver jewelry in order to increase the gloss and reduce the degree of oxidation, some manufacturers will also plate a layer of platinum on it (note that platinum is not platinum). Such products are commonly known as real money and silver products in the industry.
