We accept all major cryptocurrencies supported by Coinbase Commerce. Payments can be made directly through Coinbase accounts (including fiat payments connected to Coinbase) or via external crypto wallets such as MetaMask. You do not need a Coinbase account to complete a purchase. The minimum purchase amount corresponds to the value of the most affordable diamond available on our platform.

You can mint one NFT per transaction. However, there is no limit on the total number of NFTs you can mint overall—feel free to mint as many as you like, one at a time.

Our diamond prices are pegged to a fixed USD/EUR value and do not fluctuate with cryptocurrency market changes. However, since payments are made in crypto, the amount of cryptocurrency required to complete a purchase may vary to match the fixed USD/EUR price.

Each diamond we offer is GIA-certified and uniquely tied to a single NFT, ensuring both physical and digital authenticity. Our NFTs are deployed on Base, Coinbase’s official Layer-2 solution, offering security and scalability. Unlike many other digital assets, our diamonds are physically redeemable—holders can burn the NFT to claim the underlying diamond.

Every diamond is GIA-certified and linked directly to its NFT via metadata that stores the original GIA certificate, creating a secure digital twin. Our smart contracts are audited by leading firms to ensure maximum security. This guarantees the authenticity and traceability of both the physical diamond and its digital counterpart.

All diamonds are stored in insured and audited warehouses. When a customer redeems a diamond by burning the associated NFT, the diamond is securely shipped and fully insured by the luxury logistics provider Ferrari Group.
