3Ex - Decentralized Diamond Trading Exchange

3Ex aimed to revolutionize the traditional diamond industry by addressing its core issues of opacity, illiquidity, and high transaction costs. The company's mission was to create a transparent and efficient marketplace by tokenizing physical diamonds, allowing them to be traded freely on a decentralized exchange built on a private blockchain. This model was intended to provide a standardized pricing mechanism and open up diamond trading to a wider audience, including traders, jewelry retailers, and individual consumers, thereby increasing liquidity and market accessibility. The project appears to have been active primarily between 2018 and 2019 before becoming dormant.
