I have a ring marked 925 c on the outside with a large center diamond and two smaller stones on each side I tried fogging it but it does not fog and I am curious as to how I can tell if it is real?

Answer 1

The 925 means that the ring is suppose to be made out of a a solid cast 92.5% pure Sterling Silver. Some rings can be faked though by plating a cheap ring with Silver to make it appear as though it's solid Silver. The easiest way to see if the ring is plated is to rub something slightly abrasive on an out of sight spot on the ring and see if their is a difference in color or material between the two areas. As for the diamonds, the fog test usually works because diamonds are great at dispersing heat, which is why they don't fog like glass or Cubic Zirconium. If you want to try some other tests you can sine a light into to the stone to see if the light passes through or not. If the light passes straight through than it is not a real diamond. Each facet or cut in a diamond is meant to act much like a mirror to bounce light around inside the diamond, which is why high quality diamonds have a brilliant rainbow or spectrum effect inside the stone. Also is you have a magnifying glass you can look at the the stone for tiny black specs inside the stone. These are known as carbon deposits, and are much Earth's little fingerprints verifying that the stone formed in the ground. Even the most pristine diamonds have tiny flaws in them. Another test you could try is placing the diamond on some sort of paper with small font print. Because diamonds are crystals and form in the ground, their molecular structure does not allow them to be transparent or easy to see straight through, so any kind of writing or print on a paper would be extremely difficult to read. There are several other tests you can do, but these are the most common and easiest to perform. I hope this helps some and if all else fails there is always the sure fire way of getting it tested by a trusted local jeweler. Good luck.
