Inside the Authentication Process: How ESG Luxury Ensures Every Piece Is Genuine
In the world of pre-owned luxury, trust is everything. From the stitching on a Chanel flap to the hardware on a Louis Vuitton Keepall, every detail tells a story. For shoppers, that story needs to be accurate. For a luxury resale brand, accuracy cannot be optional. It must be guaranteed.
This is why ESG Luxury built a thorough and meticulous authentication process that supports every item sold through Reunited Luxury. Our approach combines expert knowledge, trusted sourcing, hands-on inspection, and technology backed verification. Together, these layers form one of the most comprehensive authentication models in the industry.
1. It Begins With Trusted Sourcing
Before a piece ever reaches our authentication team, it begins with where it comes from. ESG Luxury sources exclusively from vetted suppliers who have established reputations within the luxury resale ecosystem. These relationships are built on transparency, consistency, and years of proven trust. Our suppliers understand the standards required to work with us, and each piece they provide must meet those expectations from the start.
Even with this level of trust, our process does not end at sourcing. It is only the beginning.
2. Verifying the DNA of Every Brand
Every luxury house has its own unique craftsmanship, signature details, and production methods. Chanel follows precise quilting alignment rules. Hermès relies on hand stitched techniques passed down through master artisans. Louis Vuitton uses materials and hardware finishes that shift subtly from one production era to another.
Authentication starts with understanding the history and construction of the piece. Our team studies brand lineage, design evolution, and manufacturing standards to identify the authentic characteristics that define each item.
3. Material and Craftsmanship Analysis
Once pieces arrive in our hands, our experts begin a detailed physical examination. Leather grain, thread thickness, hardware weight, zipper movement, and interior lining all provide critical information.
Luxury materials have a distinct feel, sheen, and behavior. They age differently and react differently to wear. This allows our experts to confirm whether the materials match the brand’s known standards and production era.
4. Construction Details Tell the Truth
Stitch counts, seam alignment, pocket depth, stamping style, embossing clarity, hardware engraving, and even the shape of screws serve as authentication clues. These details are compared against verified references and documented authentic archives.
Construction never lies. If even one detail feels inconsistent, the item does not move forward.
5. Reviewing Serial Numbers, Date Codes, and Production Marks
Date codes and serial numbers are essential, but they must be interpreted correctly. Some brands change their systems over time, while others discontinue them entirely. Our team cross references these elements with historical production data to ensure alignment with the correct model, year, and material.
Authenticity requires both accuracy and context.
6. Studying Wear Patterns
Authentic luxury pieces age in recognizable ways. Natural leather patina, hardware softening, and edge wear appear differently on genuine materials compared to counterfeit ones. Understanding these patterns helps verify a piece’s lifespan and use history.
Wear is part of the story. And the story must make sense.
7. Entrupy Secondary Verification
As an additional layer of protection, ESG Luxury uses Entrupy technology on qualifying items to perform a secondary digital scan. This AI driven analysis examines microscopic material patterns and construction signatures to provide an added level of verification. While our authentication experts lead the process, Entrupy supports it by offering a technological confirmation that strengthens accuracy.
Human expertise and technology work together to provide the highest standard of confidence.
8. Final Review and Customer Transparency
Once a piece passes all internal checks and Entrupy verification, it undergoes a final comparative review for accuracy. After approval, the bag moves into photography, description, and listing. We clearly document condition, features, measurements, and any wear so customers feel informed and confident before purchasing.
The authentication process does not end when the bag is approved. It ends when the customer feels trust.
Final Thoughts
Authentication is not a single step. It is a layered system built on expertise, vetted sourcing, advanced technology, and a commitment to accuracy at every stage. ESG Luxury designed this process to protect the customer, honor the craftsmanship of each piece, and elevate the entire resale experience.
Reunited Luxury reflects that commitment. Each item we list is the result of careful inspection, trusted relationships, and a standard that never compromises. In a market where trust matters more than anything, our authentication process is the foundation that makes every purchase meaningful.
Luxury deserves integrity. Authentication ensures it.
