Cartier jewellery is among the most counterfeited on the market. The Love, Juste un Clou, and Trinity are particularly targeted.
Every 18-karat gold piece has a precise weight, regulatory hallmarks, and a unique serial number. Our gemologists at HAUTANE verify these first.
This guide covers the 8 essential criteria for all Cartier jewellery: bracelets, rings, necklaces, earrings.
If in doubt, authentication is free at HAUTANE and completed within 4 hours by our gemologists.
750 hallmark (18K gold). In France: mandatory eagle's head. Struck, not engraved.
Tip : 10x magnifying glass: the hallmark must be crisp and deep.
Unique, 3 letters + 3 digits (e.g. ABC123). Laser-engraved on recent models.
Tip : Usually engraved inside, near the hallmark. Legible but discreet.
Specific typography with a characteristic capital C. Fine, crisp, uniform depth.
Tip : Compare with official photos: the C and r have very specific shapes.
18K gold: density 15.58 g/cm3. Classic yellow gold Love size 17: approximately 33-34g.
Tip : Precision scale (0.1g) and compare with official specifications.
Perfectly polished and rounded. No sharp edges. Uniform mirror polish.
Tip : Run your finger along the edges: absolute smoothness, no snagging.
Love: special screws with Cartier screwdriver. Post-2017: captive screws. Juste un Clou: hinged clasp.
Tip : Post-2017 Love: screws turn but do not come out.
Red leather box, cream suede interior. Certificate with serial number and hologram.
Tip : The box alone proves nothing, but its absence affects resale value.
Hallmarks vary by country: eagle's head (France), owl (EU import). Struck by official bodies.
Tip : Jewellery purchased in France without an eagle's head: parallel import to verify.
Weight (approximately 33-34g yellow gold size 17), 750 hallmark, serial number, Cartier engraving, and screw system. HAUTANE authenticates free of charge.
No. Authenticity is verified on the piece itself (hallmarks, weight, engravings).
Yes, it is one of the most reliable criteria. 18K gold has a density that counterfeits cannot replicate.
