Certificate of Authenticity
Your Jewelry Certificate
Every piece of jewelry has its own certificate: a unique document with an identification number and a description of the metal and stones. You receive it on a card with an NFC chip: hold it near your phone to open and download it.
How It Works
One Card, Your Certificate
- Receive the card with your jewelry. It has an NFC chip, the same technology used for contactless payments.
- Hold it near your phone. Your jewelry's certificate page will open. No app installation is required.
- View and download it. You can read it on your phone and save it as a PDF.
Where to Tap the Card
- iPhone XS and later. With the screen on, hold the card near the top of the back and tap the notification that appears.
- iPhone 7, 8, and X. Open the Control Center and tap "NFC Tag Reader." If it's not there, add it via Settings > Control Center.
- Android. Search for "NFC" in Settings and enable it, then place the card against the center of the back.
- With a case. A thick or metallic case may shield the chip: if the card won't read, remove the case.

Card Not Reading?
