How can I authenticate a fake Bvlgari B.Zero1 ring?

Key features to look for in a genuine Bvlgari B.Zero1 ring include the materials and stamped lettering on the ring. All genuine B.Zero1 rings from Bvlgari are made of 18K white, yellow, or rose gold. White gold can become less brilliant over time, but fakes made of cheaper silver will show obvious discoloration. The logo and lettering of BVLGARI should be clearly and evenly stamped twice around its band. Bvlgari rings have inspired fakes over the years, so it’s important to purchase from a certified seller.
