# Carats Redemption Any owner of enough Carats can redeem a Diamond Standard Coin or Bar token without asking for permission (subject to KYC). A user who owns a BCC or BCB token can take delivery of a Diamond Standard Coin or Bar on demand, subject only to shipping fees. Holders of 10 BCC tokens can exchange them for 1 BCB token, or vice versa. Using the Token Exchanger ([app.diamondstandard.co](http://app.diamondstandard.co)), Carats on any supported blockchain are converted into BCC or BCB tokens, which users self-custody in a digital wallet. There are currently no fees, other than gas. BCC or BCB token holders can trade them for USDC on the Diamond Standard Marketplace ([spot.diamondstandard.co](http://spot.diamondstandard.co)), which also charges no fees. Users must complete a KYC and AML review to register on the Diamond Standard Token Exchanger and Diamond Standard Marketplace. There may be a KYC processing fee. The exact amount of Carats needed to redeem a Diamond Standard Coin or Bar depends on whether you select delivery or custody. To custody a Coin or Bar in an approved vault (required to enable digital trading or conversion to Carats), users need to remit extra Carats to pay for 1 year of custody (currently $36 per Coin and $240 per Bar). To have the custodian ship a commodity to you (currently USA, Canada, EU, and Switzerland only), extra Carats are required to pay for shipping. Vault pickup is not offered. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
