The difference between platinum ring and white K gold ring
Platinum and white K gold are difficult to distinguish to the naked eye. If you want to identify the two clearly, you still need some methods.
Platinum: Platinum (PT). Natural element platinum is a rare valuable metal element in the crust. It is more stable than gold and is more expensive than gold.According to national precious metal jewelry standards, only platinum can be called platinum.The "PT900" or "PT950" seen on the products of jewelry stores represents 90%and 95%of the platinum content in the jewelry.In addition, only plain jewelry with more than 85%of platinum can bring any of the following propaganda -platinum, platinum, platinum or PT.PT850, PT900, PT950, and PT990 are the most common.
White K gold: It is a white alloy melted from gold and nickel, silver, copper, zinc and other metals. 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.When buying, just turn the jewelry in your hand to the back. The real platinum jewelry, whether it is a ring, a pendant, or a large earrings, will have a small marking: PT900 or PT950.
White K golden labels indicate K numbers.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:
Platinum density is the largest in inlaid metal, so the same style and size of platinum of the same style and size are much heavier than white K gold jewelry, which is obviously heavy.Even a simple wedding ring made of platinum is obviously heavier than white K gold.
4, color:
The color and luster of platinum are naturally natural, and it is not changed for a long time.Pure platinum is silver -white with metallic luster.
White K gold obtains a white appearance by melting gold and other metals.The color of the white K gold is white beige, because the color is usually enhanced with surface plating, but this electroplating will wear, so that it shows the dark yellow inherent in white K gold.
5. Burning melting:
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 the K gold jewelry is a kind of smoke -gray oxidation layer, and the lower the color, the darker.
6. Test:
Platinum will not be polluted on platinum on platinum, while K gold will be contaminated with mercury.
The difference between platinum ring and silver ring
There are five ways to identify whether there are platinum or silver. The current division is described as follows:
1. Comparison method: Platinum is gray -white with the naked eye, the texture is hard, and the hardness is 4.3.The silver is looking at it with fleshy eyes, the color is white, the texture is more delicate and light, the hardness is lower than that of platinum, and the hardness is 2.7.
2. Read the seal: Because each piece of jewelry must be engraved with the printing of the ingredients, as long as you see PT or Platinum, Plat, that is platinum; if you see S or see Silver, it is silver.In addition, pay attention to copper silver -plated symbols, it is SF.
3. Weight: If the seal is blurred, or the seal has been intercepted, this method can be used.The density of platinum is high, the proportion is 21.4 kg/cm 3, and the proportion of silver is 10.49 kg/cm 3.In this way, the weight of the same volume of silver is only half of the platinum, and the two are easy to distinguish.
4. The cremation method: Sometimes I encounter less materials. It feels not obvious to put it on the hand, and at the same time, there is no seal, so this method has to be adopted.Platinum is warm or burned, and after cooling, the color is unchanged; while the silver is heated or burned, and after cooling, the color is red or black.
5. Chemistry method: Grind the platinum on the test goldstone, and then add a few drops of mixing liquid with nitric acid and hydrochloric acid. If the grinding marks exist, it means that the platinum is platinum.On silver, the grinding marks will be lost.
