The difference between the 18K diamond ring and the platinum PT50 diamond ring

The main difference between the 18K diamond ring and the platinum PT950 diamond ring is that the PT950 is high, does not fade, difficult to process, the material is platinum alloy, 18K gold high hardness, easy processing, high cost performance, the color of the inside and outside after 18K white fades, rose gold does not not gold. meeting.

18K gold refers to the gold content range of more than 750.0 ‰ and less than 916.0 ‰. The PT50 is not found in national standards, and the market cannot be found. Platinum is greater than 950.0 ‰ and less than 990.0 ‰.

The difference from four aspects: material, value, use scenario, and purchase of reference.

. The difference between material: According to national standards GB 11887-2012 "Regulations and Naming Methods of Pure Pure of Jewelry", on February 11, 2015, the National Standardization Management Commission approved the release of the release of the this Standard No. 1 modification form will be implemented from May 4, 2016.
The purity is expressed at the minimum value, and there must be no negative difference. The purity range of precious metals and its alloys is shown in the table.
18K gold has two colors commonly used in rose gold and white. It is used to 18K gold and 18K platinum.
The main components of 18K gold are gold (AU). 18K white now most of the gold content is 75%. In addition, it is added with copper nickel -zinc and other materials. And more durable. In some exquisite objects, they are used with gold and silver. Such a gold alloy is all white, without electroplating, the color is completely the same, but the cost is high, and few businesses in China use it.
The main components of the PT950 are platinum (PT), generally platinum and copper, and there are platinum plus gold.

. The difference between value: 18K gold price is lower than the PT950, the market price fluctuates, there is no example here, the price difference is that the price of platinum is already high, the second is PT950 containing PT950 The proportion of high -priced materials is greater, and the third is that platinum processing is more difficult.

. The difference between the use of the scene: 18K gold is widely used in the base material inlaid with various gems. The cost is low and the hardness is high enough. It is an ideal inlaid material.
PT950 platinum, mostly used for making platinum pure jewelry, a small amount for inlaid, difficulty in processing, and maintaining its true nature.

. In the case of inlaid diamonds or other jewelry, it is recommended to choose 18K gold, higher hardness, not easy to deform, and inlaid gemstone more firm and reliable. 18K gold has higher cost performance. However, the 18K gold and white are worn out and fade, and the color of the inside and outside is inconsistent. The 18K rose gold is the original color.
If it must be used as inlaid materials, PT900 is recommended. Generally speaking, platinum processing is more difficult than 18K gold.
