The letter marks on the inner wall of the diamond ring that we can see are nothing more than these types: G18K, AU750, G750, PT900, PT950, PT990, PD900, PD950, etc. These seemingly mysterious marks are the material and material content of the ring, similar to human identity. Among them, the material of PD900 and PD950 diamond ring is palladium, the content is: 90%, 95%. The G18K, AU750, and G750 diamond rings are made of 18K (75% gold). The diamond ring material of PT900, PT950 and PT990 is platinum. The platinum content behind the letter is: 90%, 95%, 99%. Palladium is the cheapest of these three types materials, while 18K is a good choice for setting diamonds.
This type of label often represents the nature of the ring material metal, 18K metal in gold is the alloy of gold and other metals; 24K is the real pure gold, 18K gold is suitable for making jewelry, so we call the 18K white gold, 18K pure gold in the market is wrong, this is a statement that merchants mislead consumers. The state stipulates that only platinum can be called platinum. 18K white gold can only be a popular saying. The written expression can only be called 18K white gold. The name of 18K white gold can be misunderstood as impure platinum.
Platinum can only be marked with the beginning of PT, generally there are several specifications of PT900, PT950, PT990.
Palladium is a member of the platinum group, a noble group of platinum group metals, and palladium and platinum are widely associated with each other. Palladium and platinum have similar appearance and hardness, and have a silvery white color and a metallic luster, chemically stable. Platinum and palladium are the two minerals with the smallest reserves in the platinum group, which are also rare. However, it is strictly different from platinum: one is that the palladium component is “pd”; the second is that the price of palladium is less than half of that of platinum; the third is that the palladium is lighter than platinum, and it will be grayed out when exposed in the air for a long time.
In addition, some begin with D, followed by some numbers. D is the first letter of the English word "diamond". For example, D050 refers to a diamond of 50 points (0.5 CT). D131 d0075, referring to the main stone 1.31 carats, the side stone 7.5 points (0.0075 carats).
The diamond ring has some other symbols besides the above common symbols, some are the company's abbreviation, production place, manufacturer, brand label, etc., some will also mark the cut, clarity, and color grade, etc.
