Responsibly sourced gemstones from the female miners of Tanzania

Welcome

Moyo Gemstones is an ethical gemstone collaboration born in Tanzania. We are working with female artisanal gem miners of the Umba Valley to assure rubies, sapphires, tourmaline, garnets, citrines, and amethysts, from mine to market.

We work to empower women miners to work safely, mine better, improve financial security, and create stable, equitable markets for fair trade.

What's behind a name?

Moyo means 'heart' in Swahili (the dominant language in Tanzania) and in a few other languages around the African continent. We call Moyo Gems truly beautiful 'gems from the heart'.

How do I buy the gems?
