The Chaumet Joséphine collection, with its iconic pear-shaped diamond and bee motif, is a prime target for counterfeiters. As 2026 approaches, new generations of fakes attempt to mimic the intricate setting and hallmarks. This checklist gives you the quick verification steps to separate genuine Joséphine pieces from clever impostors.

Hallmarks and Stamps
Authentic Chaumet Joséphine pieces carry clear, deep hallmarks: the eagle's head for 18k gold, the 750 stamp, and the maker's mark. On white gold or platinum, look for “950” and the Chaumet logo in an oval. Counterfeits often have shallow, blurry stamps or incorrect fonts. Use a loupe to examine the stamp area; genuine engravings have sharp edges and consistent depth.
The Pear-Shaped Diamond Setting
The Joséphine’s signature pear-shaped diamond is set in a six-prong claw that allows maximum light. On fakes, the diamond may be too shallow, the prongs uneven, or the stone not perfectly centered. Genuine settings have a fine milgrain detail along the edge of the mounting. Run your fingernail over the setting – authentic milgrain feels like tiny beads, not a continuous line.
The Bee Motif Details
Most Joséphine pieces incorporate the Chaumet bee, symbolizing Napoleon’s emblem. On an authentic piece, the bee’s wings have distinct vein lines and the body is perfectly proportioned. Fakes often simplify the bee into a blob, lose the leg definition, or use a casting that leaves seams. The bee should be crisp and three-dimensional, with no rough edges.
Clasp and Chain Construction
On necklaces and bracelets, the clasp is a hidden spring-ring or a fold-over with double safety. The chain links are round and smooth, with no gaps. Counterfeit chains may feel tinny, have visible solder marks, or use a lobster clasp with a thin spring. A genuine Joséphine chain will have a satisfying weight and the clasp will snap shut with a clean sound.
Weight and Proportion
Weigh the piece if possible. An authentic Joséphine ring in size 6 typically weighs between 5 and 8 grams, depending on metal and diamond size. Necklaces are heavier. Counterfeits often use hollow gold or thinner metal to reduce cost, making them feel noticeably lighter. Compare the weight to known specifications from the brand.
Certificate and Packaging
Every new Joséphine piece comes with a Chaumet certificate of authenticity, a serial number, and a box with a specific interior shape. The box is leather-covered, not cardboard. The certificate has micro-printed text and a hologram. Fakes may include a generic card or a poorly printed booklet. If in doubt, reach out to us for a quick check.
