Our Authentication Process

Two methods. Zero compromise.

Step 1 - Entrupy AI Scan

Entrupy uses a proprietary microscopic imaging device combined with machine learning trained on millions of luxury item data points.

The device captures microscopic images of the bag's material, including stitching, leather grain, canvas weave, and hardware coating, then compares them against a verified database to determine authenticity.

Every Hermes, Chanel, Louis Vuitton, and Dior bag we receive undergoes an Entrupy scan as the first line of authentication.

Step 2 - Check Check Expert Review

Following the Entrupy scan, every bag is reviewed by a Check Check certified specialist who examines date codes, hardware stamps, stitching, alignment, interior labels, and brand-specific authentication markers.

Authentication Certificate

Every bag sold at The Crest Vault ships with a digital authentication certificate containing:

• Entrupy scan result and reference number
• Check Check verification ID
• Bag condition assessment
• Photo documentation
• QR code for instant verification

If a bag cannot pass both authentication steps, we do not list it. Period.
