Hi that sounds like an interesting way to test for genuine diamonds. Have you tried this test yourself? is it very reliable? Thank you! Naomi

Gold With Diamonds by: Anonymous
375 is the amount of gold. if you go to a jeweler he will tell you if the stones are real diamonds & if you have a magnifying glass or Jewelers Loupe, look closely at the stones & if you can see through them they are not real diamonds & if you can't see through them, they are real diamonds. good luck & have fun

Hi Laura
thank you for sending in the following hallmark question:
"I have a 9ct gold bracelet with what I believe is cubic zirconia stones all the way round. On the back of the clasp where the hallmark is stamped 375 you can also see a panther? Does this ring any bells to anyone?"
Laura, first up - the stones that go all the way around the bracelet - like a tennis bracelet could be glass, zircons, natural or synthetic zircons , colorless zircons can be mistaken for diamonds and diamonds mistaken for zircons.
