There are a lot of friends who have been confused about the difference between Platinum and K Gold. Here, I will give you some tips. The precious metals commonly used for setting high-end jewellery are mainly two kinds, gold (chemical element is Au) and platinum (chemical element is PT). Jewelry counters in China are also generally used to refer to platinum as platinum or platinum. Because the texture of 24K gold is soft, the inlaid jewelry is mostly 18K gold. K is a unit of purity, 1K = 4.167%, so 18K = 75%, 24K = full gold, sometimes we will see in the jewelry with G18K or Au750 refers to the 18K gold. 18K gold is an alloy composed of 75% gold and another 25% of other precious metals. Due to the different composition of other precious metals, 18K gold will have yellow 18K gold, white 18K gold and rose red 18K gold. Platinum is also relatively soft if it is a platinum-plated texture. Therefore, as a mosaic jewelry, it is only used in purity of 95% and 90%. It is called PT950 or PT900. The PT stamp is also engraved on the jewelry. Comparison of 18K gold and platinum: Advantages of 18K Platinum: 1. High hardness and good ductility, it is very suitable as a jewelry gold for inlaying. It will not scratch and deform for long-term wear. Generally, for group inlays or large carats, 18K gold can provide better safety. 2. The color is variable, and different colors of white, yellow and rose red can be formed according to the composition of the other 25% precious metal doped. 3. Affordable, the price is more affordable than platinum, economical and practical. The disadvantages of 18K gold: Wear 1-2 years with the possibility of oxidative fading. Advantages of platinum: 1. The purity is higher. Generally, the platinum content is above 90%. Compared with the gold content of 75% of K gold, it obviously has higher purity, so it is more pure and will never fade. 2. More rare and precious, the annual production of platinum in the world is about 140 tons, and the annual output of gold is about 3,000 tons. 3. Platinum is stable in physical and chemical properties, has strong resistance to acid, alkali, high temperature, etc., and does not have any allergic reaction to wear, and the melting point is higher than that of gold. Disadvantages of platinum: Because of its high purity, the hardness is soft relative to 18K gold, which may cause scratching or deformation after being worn for a long time. These two metals can be said to have their own strengths, and there is no absolute difference between good and bad, mainly depending on personal preferences. If I personally, it will be more inclined to cost-effective 18K gold, the price is affordable, the hardness is high, the safety of diamonds is also strong, and the oxidative fading problem that many people worry about is actually only tens of dollars. A small problem that can be solved by re-refurbishing.
