Qu'est-ce que 925 HN stand for on my 14k white gold bangle bracelet?
925 stands for Sterling Silver and HN stands for Heng Ngai who is a jewelry maker and designer in Hong Kong. He obtained a patent in 2014 to use the image you see on your bracelet as his brand. So more than likely part of your bracelet is sterling silver or someone stamped 14k on it to fool a potential buyer.
J'ai une bague en argent qui a obtenu un 925 là. Qu'est-ce que ça veut dire?
L'argent sterling est un alliage métallique composé de 92.5% argent et 7.5% métaux de base comme le cuivre ou le zinc. La marque sur votre anneau signifie cette composition, Plutôt que de l'argent fin, qui est 99.9% argent ou argent, qui est 90% argent.
What does it mean if a gold colored ring has the words Canada and GAA 925 on the inside?
If the GAA is on the inside it is likely a makers mark. On the outside of the ring this could be related to the Canadian Gaelic sporting association. In your case it sounds like a makers mark. 925 identifies the ring as possibly Sterling Silver (Fake marks are often applied to cheap jewellery). If it is Sterling then the gold colouring could be gilt (Thin application of gold foil or paint).
