The Cartier Love bracelet is one of the most iconic pieces of jewellery ever made. Designed by Italian-born jeweller Aldo Cipullo for Cartier's New York boutique in 1969, it has been worn by royalty, celebrities, and anyone who understands that some things are worth buying once and keeping forever. Before you invest in a pre-owned Cartier Love bracelet, there is one question you need to answer first: what size do you actually need?
Getting the size wrong is not a minor inconvenience. The bracelet screws shut — it is designed to stay on. Buy too small and it will be uncomfortably tight. Buy too large and it will slide and risk damage. This guide covers everything you need to know before you shop.

How Cartier Love Bracelet sizing works
Cartier Love bracelets are sized by internal circumference in centimetres, ranging from size 15 to size 21. The number refers to the inner circumference of the bracelet — so a size 16 fits a wrist measuring approximately 14–15cm. Both the Classic Model and the Small Model use the same size numbering system across all metal and diamond variations.
The most commonly worn sizes are 16, 17, and 18. Size 16 suits slimmer wrists, size 17 fits the average wrist, and size 18 works well for those with a larger wrist or who prefer the bracelet to sit lower on the arm. Browse all Cartier Love bracelet sizes currently available on HEWI — from Size 16 to Size 18 in yellow, white, and rose gold.
Classic Model vs Small Model: what is the difference?
Cartier produces the Love bracelet in three widths — Classic, Medium, and Small. The Classic Model measures 6.2mm wide and is the original, bolder silhouette. The Small Model is 3.65mm wide — slimmer, more delicate, and ideal for stacking. Both models share the same size numbering, so the difference is purely aesthetic.
If you are new to the Love bracelet or planning to wear it with other pieces, the Small Model is a versatile starting point. HEWI's pre-owned selection includes Small Model pieces across yellow, white, and rose gold — all authenticated in-house.
How to measure your wrist at home
The most reliable way to find your size before buying pre-owned is to measure your wrist at home:
Step 1: Wrap a strip of paper or a soft measuring tape around your wrist, just below the wrist bone — this is where the bracelet will naturally sit.
Step 2: Mark where the paper meets and measure the length in centimetres. This is your wrist circumference.
Step 3: Add 1 to 1.5cm to your measurement to find your ideal size. If your wrist measures 15cm, a size 16 will give a snug, comfortable fit. Add 2cm for a looser, lower-arm fit.
If you are between sizes, size up. Once you know your size, browse HEWI's full Cartier Love bracelet selection — filtered by size in the product listings.

What to look for when buying pre-owned
Buying through a trusted platform like HEWI removes much of the risk — every pre-owned Cartier piece on HEWI has been pre-screened for authenticity by HEWI's in-house specialists. A few details are still worth checking:
The screwdriver: Every authentic Love bracelet comes with a proprietary screwdriver. Its presence is a sign of careful previous ownership and essential for wearing and removing the bracelet.
The box and papers: Original Cartier packaging and certificates of authenticity add both value and peace of mind. Always check whether the listing includes original box.
Condition grade: HEWI rates condition clearly on every listing. Light surface scratches on gold are normal and can be polished. Check the condition grade before purchasing.
Hallmarks: An authentic Love bracelet carries Cartier hallmarks on the inside: brand name, metal purity (750 for 18k gold), and a serial number. Confirm from listing photos.
Is it worth buying a Cartier Love bracelet pre-owned?
Absolutely — and for more than just the price saving. The Love bracelet is built to last generations. A pre-owned bracelet authenticated by HEWI's team carries the same quality as a boutique purchase, with a smaller environmental footprint and immediate availability — no boutique waitlist, no appointment required.
