Men。Lab Diamonds & 4x\'s Gold Plated Waterproof, No Tarnish Stainless Steel w/Shine Protection Warranty \"Look like Money without Overspending\" Yes, Real Diamonds, but they\'re LAB DIAMONDS. They do Pass some diamond testers, but definitely NOT ALL, because these are only Lab Diamonds. Some testers are only setup to read Natural Earth Diamonds. Therefore, you will not be able to trick a Pawn Shop or Jeweler that specializes in Natural Earth Diamonds. *Clean with Jewelry Rag or Mild Soap & never use harsh chemicals. Thank you for shopping with Queenie
