Read the code
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.
Don't stop at the code
A correct-looking code on a poorly-made item still means fake — and fakers copy valid codes. Cross-check the code against the physical tells below.
| 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. |
