Authentication, Process and Pricing
Precision Lies in the Details
Every luxury item has a story — but not every story is authentic.
That’s why we’ve built our process around one guiding principle: integrity at every step. At The Closet, each piece is verified using the newest AI technologies and reviewed by trained authenticators to ensure accuracy, trust, and transparency — every time.Thousands of items pass through our authentication process each month. The scale and consistency of our work reflect what’s possible when expert knowledge meets advanced technology — backed by over a decade of data and experience.
It starts with
The Right People
The items we sell come from collectors, fashion lovers, and people with great taste. They’ve taken care of these pieces and are ready to pass them on. We’re here to help find each one a new home — and let its story continue.
Inside the Authentication Lab
Our Experts and Tools
Authenticated by luxury experts
With over 15 years of experience, our in-house authenticators specialize in categories like jewelry, watches, bags, and vintage. Every item is carefully inspected in person — combining deep expertise with hands-on evaluation to ensure authenticity with confidence.
Entropy Verification
We use advanced AI technology called Entrupy to support our authentication process. Trained on millions of data points, it helps verify each item's materials, craftsmanship, and microscopic details—adding an extra layer of precision to our expert-led review.
Diamond Testers and Microscopes
We use diamond testers to verify precious stones and microscopes to examine fine details like engravings, serial numbers, and hallmarks. These tools allow us to confirm what the eye alone can’t see—ensuring every piece meets the highest standards before it reaches you.
How We Price
Our goal is simple: to get you the best possible return on your item.
With years of expertise and a deep understanding of the resale market, our team uses real data and insight to determine fair,
competitive prices that reflect both demand and value.
Rarity & Demand
We know which pieces are hard to find, which collections sold out in seconds, and which vintage items rarely resurface. Limited-edition and one-time releases often land in our store — making it a go-to destination for collectors
Current Market Insights
Our team monitors what’s trending, what’s moving quickly, and what collectors are looking for next, using live data to guide pricing decisions.
Item Condition
We consider the full condition of each piece — from good to brand new. The better the condition, the more value it holds, and our pricing reflects that fairly.
