green tree jewelry wholesale What is the difference between 24K Platinum and 18K Platinum?

wholesale sorority jewelry 1. 24K platinum and 18K platinum are wrong. The so -called K platinum on the market is wrong.
1, only platinum can be called platinum. Platinum proprietary symbols: thousands of points of platinum purity (platinum content), such as platinum 950, PT950.
2, (1) K gold is a alloy. Because white K gold is white, white K gold is the white metal that is most likely to confuse with platinum, but it is completely different from platinum.
(2) K: refers to the purity of gold.
(3) 24K -The market occasionally marked with 24K gold jewelry, but strictly speaking, 100%of gold can be called 24K gold in theory, but gold is not red.
(4) 18K — the content is 750.0 ‰ -916.0 ‰. There are many colors of K gold, usually yellow, red, and white. Among them, white K gold is actually alloy of gold, nickel, zinc, copper and other elements. It is not usually called platinum jewelry.
. The difference between platinum and white K gold:
1, ingredients:
gold, platinum (PT). Natural element platinum is a rare valuable metal element in the crust. More stable, the price is more expensive than gold. According to national precious metal jewelry standards, only platinum can be called platinum.
The white K gold is a white alloy melted from metal such as gold and nickel, silver, copper, and zinc. Its main component is still gold, and its content is up to 75%.
2, mark:
platinum indicates pt. "PT950" means 95%of platinum, and more than 99%of platinum -containing jewelry generally has a "foot platinum" mark.
Net white K gold standard K number. K is the gold content, such as 18K white, 750g, and 750 gold. The purity of platinum jewelry is not expressed as "K".
3, weight:
The platinum density is the largest in inlaid metal, so platinum of the same style and size is much heavier than white K gold jewelry, which is obviously heavy.
4, color:
The color and gloss of platinum are naturally natural, and it is not changed for a long time. Pure platinum is silver -white with metallic luster.
The white K gold is a white appearance by melting gold and other metals. The color of the white K gold is white and beige, because its color is usually enhanced with surface plating, but this electroplating will wear, so that it shows the dark yellow inherently inherent in white K gold.
5, burning melting:
The platinum melting point reaches 1773 ° C, which is much higher than white K gold. Generally, the welding gun cannot melt platinum, and the color of platinum is unchanged after cooling. The surface of K gold jewelry is a kind of smoke -gray oxidation layer, and the lower the color, the darker.
6, click Test:
The mercury on platinum, platinum will not be contaminated, and K gold will be contaminated with mercury.
Pucting data
. White Gold (White Gold), the main ingredient is 75%of gold. After adding other metals, it shows the surface of the surface. So white K gold is alloy, and it will fade or yellow after wearing it for a long time.
. When the gold is melted with other metals, due to the different types of other metals and the proportion of incorporations, they can get different colors of K gold.
. For example, after the melting of gold and copper, silver, nickel, and 钯, it presents a green alloy after different proportion, called "green K gold"; after the gold and copper are fused in a certain proportion, the rose red alloy can be presented. It is called "red K gold"; after the gold, silver, zinc, and nickel are melted according to different proportions, they can get silver -white K gold, which is called "white K gold". In addition, there are blue K gold, black K gold, etc. Essence
Because K gold is a melting alloy, its surface is consistent with the internal color, and it will not change color after wearing it for a period of time.

If looking at the gold content alone, 24K is more expensive than 18K gold. However, due to high hardness and difficulty in processing, the natural processing costs are high, so it is normal to encounter the situation of 18K gold than 24K gold.

Therefore, the golden position standard K in the gold content in the gold product generally refers to the pure gold as 24K gold, but it is theoretically gold with 100 % gold, which does not actually exist. Therefore, in the national standard, the gold content of the merchants that the gold jewelry must not use the irregular standards of "24K gold". Since the pure gold is 24K, that is, the theoretical gold content is 100 %, then 1K means that gold products contain pure gold 1/24, about 4.16 %. 18K gold represents the gold content of 18/24, which is 75%of pure gold, and the rest are other materials such as silver or copper.
