Initial Review
Detailed photography, serial numbers, stamps, packaging and paperwork are reviewed before an item arrives.
We warn sellers that if they send in a counterfeit item, they will be responsible for all costs of shipping (and duties).
Expert Physical Evaluation
Once an item comes in for review, it is physically evaluated and authenticated. Our specialists examine craftsmanship, materials, hardware, markings, gemstones and construction.
Advanced Testing
When appropriate, specialized technology is used to evaluate metal composition, diamond fluorescence and other characteristics.
How We Authenticate
We follow rigorous, brand-specific authentication practices when evaluating every piece. Our specialists examine the details, materials and construction specific to each category and brand.
- Craftsmanship: Stitching, finishing, construction and brand-specific details.
- Materials: Leather, precious metals, gemstones and other materials are evaluated against brand standards.
- Markings & Serial Numbers: We inspect stamps, engravings, serial numbers and other identifying details.
- Hardware: Hardware, clasps, zippers and other components are examined for consistency with the brand.
- Documentation: When available, we review original brand certificates, receipts, boxes and accompanying documentation as part of our authentication process.
- Condition & Alterations: We assess whether an item has been modified, repaired or altered in ways inconsistent with its original construction.
Expertise Meets Technology
Precious Metal Analysis
Our Thermo Scientific Precious Metals Analyzer helps us verify metal composition against brand standards.
UV Inspection
We use UV technology to examine diamonds and identify signs of fluorescence, alteration or third-party modification.
Authentication Is Brand-Specific
A Cartier Love bracelet isn't authenticated the same way as a Chanel handbag or a Van Cleef & Arpels necklace. Our specialists evaluate each piece against the details, materials, construction and characteristics specific to its brand and category.
