Diamond Cards

Upgrade Any Credit Card Into a Diamond Metal Card

Metal was the upgrade. This is what comes after the upgrade.

Lion Card converts your plastic credit, debit, or prepaid card into a hand-finished metal card set with genuine VS1 diamonds, via our patented EMV chip transplant, U.S. Patent No. 11,562,194, trusted since 2015.

Still your card. Same account, same number, same bank. Now it carries stones.

Why the Diamond Collection Stands Apart

Every Lion Card is engineered. These are the ones that cross into jewelry.

• Genuine VS1 diamonds: Real stones, hand set into the card face, not printed sparkle or crystal imitation.
• Hand-finished builds: Each card is finished individually by hand, with detail work our standard line does not carry.
• Up to 29 grams: The heaviest builds we make, nearly five times the roughly 6 grams of a plastic card.
• Jewelry you pay with: A stone that usually sits in a case comes out at every checkout.
• Built on the same patent: The diamonds change nothing underneath; your chip and stripe transfer intact.

How It Works

Your card gets re-engineered, not recreated. We transplant your real EMV chip into a metal body, so your account number and bank never change. Simple on your end, precise on ours.

• Order: Pick a design and get a prepaid, tracked label by email.
• Ship: Send your card, or freeze it first. We never ask for your PIN.
• Approve: Sign off on the emailed mockup before anything is made.
• Receive: Both cards come back together with tracking.

Do the diamonds change how the card works?

No. Chip insert and swipe work anywhere your original card worked, and you can tap through Apple Pay or Google Pay. Just avoid ATMs that pull the card fully in.

Are the diamonds real?

Yes, genuine VS1 diamonds, hand set into the metal. They are stones, not printed sparkle or crystal. The mockup and your pre-shipment photo show exactly what is set.

Will the diamonds stay secure with daily use?

They are hand set for everyday carry, and a dedicated wallet slot away from keys and coins protects the setting best. Treat it as any fine piece. A 30-day return applies if you are not satisfied.

Is a diamond card heavier or thicker in the wallet?

The heaviest builds reach up to 29 grams, but dimensions stay standard at 85.60 by 53.98mm and 0.8mm thick. It fits every wallet slot and reader like any card. Only the hand notices the difference.

Can I choose where the stones sit?

Placement follows the design you select, and the mockup shows every stone position before production. For a layout of your own, our custom team can build it. Nothing is set until you approve what you see.

Is a diamond card a good gift?

It is one of our most gifted builds, since it reads as jewelry and works as a card. The recipient ships their own card in after unboxing the order. Contact us at metal@lioncard.com to arrange gifting details.

Is it safe to mail you my card?

Yes. Lion Card is PCI compliant and BBB A+ accredited, and we guarantee a safe process or your money back. Freeze your card before mailing, and we never ask for your PIN or passwords.
