STEINBRILL provides the Diamond Passport and Diamond Platform, services designed to give customers access to a personalized diamond passport. The website explains how to use a compatible mobile phone to read a passport card: connect to the internet, enable NFC, and hold the card near the phone to display a password and direct access link. Customers can then open their passport either by entering the password on the checker page or following the link.

Once logged in, they can personalize the passport by adding the owner’s first and last name and a message for a loved one. The site describes the Diamond Passport as time-limited for 12 months, with an additional charge applying to any extension. STEINBRILL states that the Diamond Passport and Diamond Platform are protected by intellectual property rights in 179 countries and that it intends to protect those rights under applicable laws.

Its messaging presents the service as a way to connect a diamond with a named owner and a personal dedication
