What does it mean when my silver ring has 925 stamped with a star stamp too?
The mark “925” applied to any white metal item claims it to be made of the silver alloy that is more commonly called or known as “Sterling Silver”.
Marks applied by other than recognized government assay offices only claim verses prove the metal content of an item. Mis-marking is unfortunately quite common both in the past and present times..
Sterling Silver originally dates to the reign of English King Edward I and was originally by fractional recipe 926 parts pure silver of 1000 total parts, with the remaining 74 parts being copper.
However the Goldsmith’s Company Hall in London would allow a negative tolerance of 1 part per thousand and still apply the Lion walking hallmark for Sterling. Thus, Sterling became a minimum Silver purity of 925/1000.
Meanwhile most of Germanic Europe was on the base 16 Lothige system for silver marking. 15 Loth is 15/16 = 0.9375, which is usually rounded to 935 for millennial marking purposes. Such items are legal to sell as Sterling.
Finally a simple 5 pointed star has no generally defined or accepted meaning within the jewelry industry, that I am aware of.
What is a 925 ring with letters CN a d with a square around it and several rubies?
Hi. Mike in Houston, Texas. The answer to your question is it is a sterling silver ring. When you see the 925, it means sterling silver, but if it was 950, it would be platinum. 925 means it’s 92.5% pure silver. The CN a d is the manufacturer of the ring. The company is based out of India. That’s why you have the rubies in the ring. It’s a decent company that sells sterling silver and 22K jewelry. 22K jewelry is marked with 916. It means it’s 91.6% pure gold. The vast majority of the Indian and Pakistani population wear 22K jewelry. The Asian people wear either 18K or 24K jewelry. The European’s normally wear 18K jewelry. Then, the Americans like 18K or 14K as their jewelry. The Mexican population likes 10K jewelry. It’s marked 417, meaning 41.7% pure gold. Remember, the higher the KT weight, the heavier the jewelry will be. Gold is heavy. Thanks. Respectfully, Mike
