Authentication Checklist Buying pre-loved luxury? Run through these eight universal checks before you commit. They apply to bags, watches and jewellery from any house — tick each as you verify it.
✓ Serial / date code Look for a serial number, date code or microchip in the expected place. Cross-check the format against the house's era — fonts, spacing and heat-stamp depth should be crisp and consistent, never wobbly. ✓ Hardware weight & engraving Real hardware feels substantial and cold. Engraving of the logo, zip pulls and feet should be deep, even and correctly spelled — flimsy, light or shallow-stamped hardware is a red flag. ✓ Stitching Stitching should be straight, even, and consistent in count and angle. Luxury houses use a specific stitch density — loose, crooked or uneven stitches signal a fake. ✓ Logo & monogram alignment On patterned canvas, the monogram should be symmetrical and mirror correctly across seams. Misaligned, cut-off or upside-down logos are a classic tell. ✓ Leather & materials Genuine leather has a natural grain and smell; the lining should match the house's known materials for that era. Plasticky smell or the wrong lining is suspicious. ✓ Interior stamps & tags Blind stamps, 'made in' tags and font should match the period. Compare against verified reference photos of the same model and year. ✓ Dust bag, box & receipt Accessories should look correct for the era (the wrong logo or a too-new dust bag on a vintage piece is a warning). But note: authentic pieces are often sold without them — absence alone isn't proof of a fake. ✓ Seller & guarantee Buy from sellers with strong reviews and, ideally, a third-party authentication guarantee or returns policy. A price far below market is the biggest red flag of all. Nuvinty is a discovery platform — we curate and link to sellers, we don't authenticate items ourselves. This checklist is general guidance; for high-value pieces, use a professional authentication service or a seller that provides an authenticity guarantee.
