How do I authenticate my jewelry?

Submit clear photos of your jewelry through our order form. Our specialists examine every detail against known authentic examples and email you a verdict — authentic or counterfeit — within 24 hours, along with a Certificate of Authenticity.

Do I need to ship my item?

No shipping needed. Authentication is entirely photo-based. Upload images from the required angles and our team does the rest — from anywhere in the world.

How much does jewelry authentication cost?

Pricing depends on the category and turnaround you choose. See the pricing section on this page for exact amounts. Express options (12h and 2h) are available at checkout.

What if the result says counterfeit?

You still receive your certificate clearly stating the verdict. This protects you legally when returning the item to a seller or disputing a transaction.

Which brands do you authenticate?

We authenticate all major luxury brands in the jewelry category — including Cartier, Tiffany & Co., Van Cleef & Arpels, Bulgari, and hundreds more. If your brand is not listed, add it at checkout and our team will confirm availability.

About Jewelry authentication

Authenticating luxury jewelry requires a trained eye for hallmarks, metalwork quality, stone setting, and brand-specific details that counterfeiters consistently get wrong. Our jewelry authentication guides cover Cartier Love bracelets and Trinity rings, Tiffany and Co. sterling and gold pieces, Van Cleef and Arpels Alhambra necklaces, and more. We walk through the exact markers — from hallmark placement and font consistency to clasp mechanics and weight — that experts use to separate genuine pieces from high-quality fakes.
