Vad betyder det när min silverring har 925 stämplade med en stjärnstämpel också?
Märket "925" som appliceras på någon vit metallföremål hävdar att den är gjord av silverlegeringen som mer allmänt kallas eller kallas "Sterling Silver".
Märken som applicerats av andra än erkända statliga analyskontor hävdar endast verser som bevisar metallinnehållet i ett föremål. Felmarkering är tyvärr ganska vanligt både i förr och nu..
Sterling Silver dateras ursprungligen till den engelske kungen Edward I:s regeringstid och var ursprungligen av fraktionerad recept 926 delar rent silver av 1000 totala delar, med resterande 74 delar är koppar.
Men Goldsmith's Company Hall i London skulle tillåta en negativ tolerans för 1 part per thousand and still apply the Lion walking hallmark for Sterling. Således, 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?
Hej. 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% rent 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% rent guld. 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. Sedan, the Americans like 18K or 14K as their jewelry. The Mexican population likes 10K jewelry. It’s marked 417, menande 41.7% rent guld. Komma ihåg, the higher the KT weight, the heavier the jewelry will be. Gold is heavy. Tack. Respectfully, Mike
