Diamond Standard creates a novel, investable, and tradeable asset class through the tokenization of real, investment-grade IGI (International Gemological Institute) and GIA (Gemological Institute of America) certified diamonds.
These commodities are investment products combining real diamonds with digital blockchain technology. They offer investors a standardized unit of diamonds in the form of “Coins” and “Bars.” These can be traded for liquidity or held as investments secured by both the physical commodity and the immutable Hedera blockchain.
Each Coin and Bar contain an equivalent, optimized set of natural diamonds that add up to the same geological scarcity of carat weight, color, and clarity. Every sample and every commodity are public, and are designed to trade in lockstep market price.
Inside each asset is a military-grade wireless (NFC) encryption chip, enabling authentication, instant transactions, and remote audit.
Diamond Standard seeks to provide investors with a secure and accessible way to invest in diamonds at convenient, lower entry point via digital tokens called “Carats” issued from physical commodities.
