Brand-Specific Expertise

Every ultra-luxury handbag or accessory we receive undergoes a meticulous multi-step authentication process by a brand expert.

Counterfeit Detection

We ensure every item meets the manufacturers’ quality standards in craftsmanship, stamping, stitching, engravings, hardware, date codes, materials, and serial numbers, where applicable.

Our Expert Process

Recognizing Key Indicators of Authenticity

Authenticity lies in the details only designers get right. Each luxury brand carries its own signature markers, and our expert authenticators—trained by brand—can identify them instantly by sight and feel.

Hallmarks and Stamping

Our authentication team inspects key hallmarks—like stamping, embossing, and engraving—under microscopic scrutiny. Each element is photographed and compared against our proprietary database of high-resolution images, built from over a decade in the luxury resale industry. This data-driven process allows us to flag even the slightest deviation for further review, ensuring every piece meets our exacting standards.

Stitching

Our experts verify the authenticity of designer bags by inspecting the stitching for uniformity, consistency, and precision. They ensure even spacing, straight lines, and high-quality thread, matching original manufacturer standards.

Dimensions

Exact measurements are central to our authentication process. We meticulously record dimensions—from bag to accessory—and compare them against our proprietary database of verified specs. This allows us to detect even the smallest discrepancies and ensure every piece meets our uncompromising standards. It’s precision that reflects our commitment to authenticity, quality, and trust.

Hardware & Materials

Our authentication experts inspect the hardware and materials of designer bags to ensure authenticity. They check the quality, weight, and engravings of the hardware, and examine the material for texture, color, and durability, comparing them to original manufacturer standards. This thorough inspection verifies the genuineness of each bag.

Weight tracking

Weight is a key indicator in our authentication process. We carefully measure each bag and accessory—down to locks, keys, and hardware—and compare those specs against our proprietary database. This meticulous tracking helps us verify authenticity with exceptional accuracy, ensuring every item meets our uncompromising standards.

Serial number

Our authentication experts verify the authenticity of designer bags by examining the serial number and date code. They check the format, placement, and consistency with the original manufacturer's standards. This ensures each bag's genuine origin and production date.

Ownership History

In the secondary market, an item’s provenance matters. We verify ownership history through a straightforward process. Seasoned sellers must attest that they are the rightful owners of their items, and new sellers presenting new merchandise must provide proof of purchase.

Original Packaging

When an item includes its original box, dustbag, or case, we preserve it for the next owner to enjoy. If it arrives without accessories, we provide our own dustbag to protect your investment. For full details, refer to the “Includes” section in the product description.

Certificate of Authenticity

Every ultra-luxury piece that passes our authentication process receives a REBAGLUXE Certificate of Authenticity. This certification seals your ultra-luxury deal, guaranteeing it for life.

Our Lifetime Guarantee

Your trust is paramount to us. We guarantee the authenticity of every ultra-luxury item we sell or 100% of your money back.
