It should be S925, which is 925 silver. When used as a jewelry, it is prone to oxidation. Therefore, the highest purity is 92.5%. Themo, whether it refers to 18K gold or platinum, the unified logo in the industry is: 18K gold is AU750, G18K, G750
If it is Platinum, it should be the PT logo. PT990, PT950, PT900. If it is the S logo, it should be silver jewelry, S990, S925, etc. I guess your one should be S925, you take a closer look.
It should be S25 S25 is a domestic high -quality carbon steel 25#steel. The earliest and most dosage of carbon steel in modern industries. While industrial countries in the world, while working hard to increase the output of low -alloy high -strength steel and alloy steel, they also pay great attention to improving the quality of carbon steel and expanding varieties and use. At present, the proportion of carbon steel production in the total steel output of various countries is maintained at about 80%. It is not only widely used in construction, bridges, railways, vehicles, ships, and various mechanical manufacturing industries, but also in modern petrochemical industry in modern times. In terms of ocean development and other aspects, it is also used in large quantities.

Probably S925, it's silver
There are M15 in the diamond ring, and the S25 logo. Is this ring real?
