How do I authenticate a Cartier Love bracelet?

Check that the screws actually turn and stay captive, weigh it (solid 18k is heavy), and read the inside engraving — 'Cartier', '750'/'Au750', size, serial and hallmark, all crisp and even. For final confirmation, a Cartier boutique can verify the serial.

Does Cartier have an online serial number check?

No. Cartier has no public serial lookup. Only a Cartier boutique can confirm a serial against their records. Be wary of any third-party 'Cartier serial checker' site.

Should Cartier Love screws come all the way out?

On the modern Love design the screws are captive — they turn but stay attached to the bangle. Screws that fall out completely or are purely decorative point to a fake.

The tells

Genuine vs fake Cartier Love Bracelet, point by point

Work through every row. No single line is proof on its own — counterfeiters fix the famous tells first — but the more boxes that fail, the more confident you can be.

What to check	Genuine	Fake
The screws	The oval screwheads actually turn with the branded screwdriver and stay captive in the bangle (they don't fully fall out on the modern design). Screw motifs are evenly spaced and aligned.	Fake 'screws' are decorative/fixed, misaligned, or fall out; spacing between motifs is uneven.
Weight	Solid 18k gold gives real, dense heft (a size 17 sits around ~30g+ depending on width).	Noticeably light — hollow or plated base metal.
Hallmark engraving	'Cartier', '750'/'Au750', size, serial and poinçon are shallow, crisp and evenly spaced.	Deep, uneven, misspelled, or missing metal mark; font that's slightly off.
Gold color & finish	Consistent, warm 18k tone with a smooth polished surface; no discoloration at edges.	Brassy or pinkish off-tone, plating wear at high spots, or a too-yellow flash.
Acid/metal test	Tests as solid 18k (750) gold throughout.	Plated: a jeweler's test reveals base metal under a thin gold layer.

Serial / date code

The Cartier Love Bracelet engraved hallmark + serial

Engraved hallmark + serial

Format: A genuine Love bracelet is engraved on the inside with 'Cartier', the metal mark ('750' or 'Au750' for 18k gold / 'PT950' for platinum), the size number, a serial number, and a small hallmark/poinçon. The lettering is shallow, precise and evenly spaced.

Where to find it: Inside surface of the bangle, opposite the screw motifs.

How to verify (honest): Cartier does not run a public serial checker; only a Cartier boutique can confirm a piece (and authenticate via the serial in their records). The strongest physical tells are weight and the working screws — but for a four-figure item, in-boutique verification or a marketplace authentication service is worth it.
