MAC Certified

MAC Certified is our mark of a piece that has passed our authentication process. Every item is physically inspected by our expert in-house specialists, guided by a 100-point checklist informed by years of experience with the brands we offer.

For bags priced at $10,000 or more, we include an additional review by an independent authentication specialist. For bags below $10,000 and for jewelry, this service is available upon request for a fee.

Every MAC Certified piece receives our MAC Certificate of Authenticity. Pieces that also pass independent authentication receive the independent authenticator's certificate.

The Path to Certification

Authenticating a luxury piece requires more than recognizing a signature stamp or familiar silhouette. It requires an understanding of materials, craftsmanship, and design, and of how those details evolve across collections and decades.

Our specialists examine the individual features and consider how they come together to form the complete piece.

How It Works

The MAC Authentication Process

The Initial Examination

Our in-house team begins with a close examination of the item's condition, construction, materials, and visible details. This establishes an overall picture of the piece and identifies features that warrant closer attention.

Condition and authenticity are assessed separately. Our specialists document signs of age and wear as part of the condition review, while evaluating authenticity through a brand-specific examination.
During the physical inspection, we photograph the piece's key features to support our review and maintain a reference record for future evaluation.

A Detailed Assessment

Guided by our 100-point checklist, our specialists examine the details relevant to the piece. These may include materials, workmanship, stitching, hardware, stamps, markings, interior construction, lining, zippers and closures, and date or serial information where applicable. No single feature establishes authenticity. Our specialists assess whether the details, considered together, are consistent with the relevant house, model, materials, and period. Original receipts, packaging, and accompanying documentation can provide valuable context, but they never replace examination of the item itself.

Independent Review and Certification

For bags priced at $10,000 or more, we submit photographs and supporting information to an independent authentication specialist for an additional expert assessment. This review is also available upon request, for a fee, for bags below $10,000 and for jewelry. Our independent authentication providers are Bababebi and Authenticate First for Hermès, Zekos Authentication for Chanel, and LegitGrails for Van Cleef & Appels, Hermès and other branded jewelry.

A piece receives MAC Certified status only after completing all applicable stages of our authentication process. We then issue its MAC Certificate of Authenticity, together with the independent authenticator's certificate when that additional review has been completed. MAC certification is issued by Madison Avenue Couture. It does not represent inspection, approval, or endorsement by the original luxury house.
