Initial Review
The initial review of an item being offered to us for purchase is via detailed photos of the item, the paperwork and box that come with it, prior to receipt.
Many counterfeits are rejected at this step. Reasons for rejection at this initial stage can include, but are not limited to:
- incorrect serial numbers
- serial number not appropriate for that model
- missing stamps
- stitching not to brand standards
- brand logo mis-sized
Furthermore, 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.
Each product team runs their own authentication process. Each team has decades of experience in its respective category and follows the most stringent practices when evaluating and authenticating products.
Further reasons for rejection at this stage can include, but are not limited to:
- material not to brand standards
- diamonds not to brand standards
- quality control (finish) not to brand standards
- metal composition not to brand standards
Brand Paperwork
Part of our authentication process is to request any brand paperwork and receipts from the seller. As such, we typically get brand certificates and/or receipts for approximately half of the items we buy from Cartier and Van Cleef & Arpels (most other jewelry brands do not provide such certificates of authenticity).
Expertise Meets Technology
Precious Metal Analysis
Our Thermo Scientific Precious Metals Analyzer helps us verify metal composition against brand standards.
UV Inspection
UV technology checks diamonds for fluorescence and detects certain signs of alteration or third-party retouching.
Brand-Specific Expertise
Our specialists evaluate each piece according to the characteristics and standards relevant to its brand and category.
