How to Authenticate Bulgari (BVLGARI)
The Roman house founded in 1884 is heavily targeted by counterfeiters — especially the Serpenti coil bracelet and B.zero1 ring. Six checks to protect Bangkok buyers.
BVLGARI Engraving — V not U
✓ Authentic
All authentic Bulgari uses the ancient Latin "BVLGARI" — U written as V, referencing Roman stone inscriptions.
✗ Fake indicator
"BULGARI" with a U is always a fake. This single check eliminates most counterfeits immediately.
Hallmark & Gold Purity Stamp
✓ Authentic
Authentic: 750 (18k gold) or 585 (14k). Italian pieces carry a government assay mark (star in oval). Location consistent per piece type.
✗ Fake indicator
Missing or illegible hallmarks. Incorrect purity. Counterfeit stamps are usually shallow and poorly defined.
Serpenti Spring Mechanism
✓ Authentic
Each coil segment individually articulated, smooth movement, substantial spring tension. Head: crisp scale texture, cleanly set stones.
✗ Fake indicator
Stiff or mis-aligned segments. Visible mold seams on head. Flat or glued stone settings. Flimsy spring tension.
B.zero1 Spiral Weight & Finish
✓ Authentic
Heavy for its size (solid gold). Logo cleanly engraved on barrel. Spiral wings flush and uniformly spaced. No wobble between barrel and wings.
✗ Fake indicator
Lightweight = hollow plated base metal. Blurry or stamped (not engraved) logo. Barrel wobbles. Sharp or uneven spiral edges.
Gemstone Setting Quality
✓ Authentic
Pave and bezel settings precise. Stones flat and evenly spaced, no glue residue. Colored stones show natural variation under light.
✗ Fake indicator
Uneven stone heights, visible glue, rocking stones. Fakes use glass or low-grade synthetics — uniform color with no depth.
Interior Markings & Serial
✓ Authentic
Post-2000 fine jewelry includes model number or serial inside (B.zero1 barrel, Serpenti clasp). "BVLGARI ROMA" engraving on higher pieces.
✗ Fake indicator
No interior marking, or wrong position. Counterfeit serials repeated across multiple pieces or wrong format.
The single fastest check
Look for "BVLGARI" with V — not "BULGARI" with U. Every authentic piece uses the Roman spelling. This test alone eliminates 90% of counterfeits within 30 seconds.
