Short Answer
A fake Hermès Constance 24 is a counterfeit copy of the 24 cm Constance shoulder bag. No single detail proves a bag is genuine. Authentication depends on a group of features that must all agree: the blind stamp, the saddle stitching, the rotating H clasp, the leather grain, and the original paperwork. One flaw is enough to raise doubt, and one correct detail is never enough to confirm a bag is real.
Prerequisites
- A 10x jeweler's loupe or a phone with a macro lens
- A soft measuring tape or ruler
- Bright, indirect daylight
- Reference photos of a known authentic Constance 24 for side by side comparison
What the Constance 24 Is
The Constance is a flap bag with a long shoulder strap, a removable strap option on some versions, and a large rotating H clasp on the front. The 24 cm size is the larger of the two classic sizes, with the 18 cm version sitting below it. Hermès introduced the model in 1959, and it is named after the daughter of its designer, Catherine Chaillet. Common leathers for the Constance include Epsom, Swift, and Togo, plus exotic skins on limited runs.
Step 1: Read the Blind Stamp
Locate the blind stamp on the interior leather, in most cases on the back wall behind the flap. It is heat pressed with no ink, so it should look like a shallow impression in the leather itself. A genuine stamp reads HERMÈS PARIS with MADE IN FRANCE beneath it, plus a letter that indicates the production year and a small artisan or atelier code. Counterfeits show a stamp that sits too deep, letters with uneven spacing, or a year letter that does not match the style of the bag it is on.
Step 2: Examine the Stitching
Look at the flap edge, the strap, and the interior seams under a loupe. Hermès leather goods use saddle stitching, which means two needles pass through each hole from opposite sides. The result is a tight, angled line with consistent tension and no loose tails. Machine stitching on a counterfeit runs flat and straight, with a uniform look and thread that sits on top of the leather instead of sinking into it.
Step 3: Inspect the H Clasp and Hardware
Turn the H clasp and feel the resistance. It should rotate with firm tension and lock into the closed position with a clean snap. Check the engraving on the hardware, which should be crisp and shallow. Fake Constance bags have clasps that wobble, plating that flakes at the corners, and hardware that feels light for its size.
Step 4: Check the Leather Grain and Shape
Compare the grain across the front flap and the back panel. On Epsom the embossed grain is fine and even, while Swift and Togo show a softer, natural pattern. Counterfeit leathers show the same repeating grain pattern across the whole bag, a plastic sheen under direct light, and a flap that curls at the edges after light use.
Step 5: Review the Documentation
Match the receipt, dust bag, box, and rain cover to the era of the bag. Hermès sells leather goods through its own boutiques and its official site, not through wholesale or factory direct channels. Any seller advertising bulk wholesale pricing on a Constance 24 is selling counterfeit goods.
Step 6: Get a Professional Opinion
Send clear photos of the stamp, hardware, stitching, and interior to a third party authentication service before you buy or resell. A boutique can refuse to service a counterfeit item, but that is not the same as a formal authentication report.
Legal Note for US Buyers
