1. View logo: BVLGARIlogo will be on the genuine Bulgari ring, and whether this LOGO is laser engraved or cast engraved needs to be distinguished. Bulgari used casting engraving in the position of lobster clasp. The characteristics of casting engraving are deep engraving and smooth bottom. The most obvious point of laser engraving is shallow engraving, and the bottom of engraving font has rashness.
2. Specific gravity test: put the ring on your hand and weigh it. If it feels lighter than silver, copper, iron and other items of the same size, it is likely to be fake.
3. Test the lipophilicity: dip a small amount of cooking oil with a cotton swab and smear it on the ring. If there is obvious black oil stain on the surface of the ring, it is likely to be fake.
4. Look at the professional certificate: If you buy something from a specialty store, you can ask the store to show your professional certificate.
5. Fog test: put your finger on white paper, and then put the ring on your finger. If you can see the fog between your finger and the ring on the paper, it is probably fake.
6. Magnifier observation: Use a magnifying glass to observe whether there are tiny scratches or oxidation marks on the surface of the ring.
7. Price inquiry: If the price is too low, it is likely to be fake.
