What does, 925 and what looks like two circles side by side then a cz, mean on the inside of my ring? It's a silver looking ring with one big green jewel in the center and three small diamond looking jewels on each side of it.

2. Check the Setting - Real diamonds are normally set in yellow gold, white gold or platinum settings. Check the stamps inside the setting. If you see: 10K, 14K, 18K, 585, 750, 900, 950, PT, or Plat, the setting is gold or platinum, that is a good indicator that the stone set in it may be a diamond. However, if you see the letters GF, RGP, or GP, these indicate the setting is gold plated or gold filled. If you see: sterling, 925, 9.25 or .925, the setting is sterling silver. If the setting is not gold or platinum, the stone is most likely not a diamond. However, several popular jewelry designers, such as David Yurman, Judith Jack, John Hardy and others are setting semi-precious stones and diamonds in sterling silver and/or gold settings so while this is an indicator, the stamp in the setting is not a definitive way to determine if the stones in the setting are or are not real diamonds. Likewise, if you see a stamp that says C.Z., this indicates the center stone is a cubic zirconia (regardless of what metal the setting is), although not all settings with cubic zirconias are marked that way.
