Moyo Gemstones is an ethical gemstone program with female artisanal gem miners in Tanzania’s Umba Valley and beyond. The effort is building the first scalable, artisanal and small-scale mined colored stone sourcing program, to assure responsibly produced, ASM-mined rubies, sapphires, garnets and tourmaline, from mine to market. The program empowers women miners to work safely, mine better, improve financial security and create stable, equitable markets for fair trade. In addition to Pact, the program’s partners include the Tanzanian Women Miners Association (TAWOMA), Nineteen48, ANZA Gems and blockchain provider Everledger. Moyo means "heart" in Swahili.
