Authenticity

Our Process

Initial Evaluation

We begin with a comprehensive physical review of each item, examining:

• Materials and construction

• Stitching, hardware, and finishing

• Date codes, serial numbers, and brand markings

• Overall condition and consistency

We assess whether the craftsmanship and design align with the standards of the original house.

Independent Technology Verification

For eligible brands and categories, we utilize advanced authentication technology from Entrupy, an industry-recognized AI-based verification system trained on extensive luxury product data.

This provides an additional, data-backed layer of validation beyond visual inspection alone.

Final Review & Documentation

Only items that pass our internal review and verification standards are accepted.
Pieces that do not meet our criteria — whether due to authenticity concerns or condition — are declined.

We do not list items that we cannot confidently stand behind.

Our Guarantee

We guarantee the authenticity of every item sold through Second Author.

If any item purchased from us is ever proven inauthentic by a reputable, recognized authentication authority, we will provide a full refund in accordance with our policy.
