Our Roots in
East Africa.
Mzizi Gems (Swahili for 'Root') bridges the gap between East Africa’s richest mineral deposits and the global luxury market. Founded by direct sourcing partners Colin Stuart and Sanaa Khalid, we work directly with artisanal miners across the Mozambique Orogenic Belt—ensuring mine-to-market transparency, ethical integrity, and unmatched gemstone quality.
Mission Statement: Responsible Sourcing
We prioritize direct engagement with small-scale miners in regions like Taita-Taveta and Kitui, Kenya, alongside Merelani, Tanzania. Every gem carries a commitment to economic empowerment and environmental dignity.
Fair Deal for Miners
Guaranteeing premium pricing for our ASM partners to foster long-term community financial independence.
Mine-to-Market Traceability
Detailed documentation authenticating origins, guaranteeing 100% conflict-free and authentic regional origin.
Community Investment
Directly funding educational initiatives and clean water projects in our mining host communities.
Low Eco-Impact
Encouraging low-impact artisanal mining methods that safeguard natural landscapes and biodiversity.
Our East African Treasures
Extracted directly from the Mozambique Orogenic Belt. Available in both exceptional rough crystals and precision-cut faceted stones.
Rubies & Sapphires: Rift Corundum
Formed deep within Kenya's metamorphic rocks along the Great Rift. These vibrant corundum stones range from glowing pigeon-blood rubies to captivating deep blue sapphires.
Tanzanite: The National Treasure
Exclusively mined in a tiny 4km strip at the foot of Mount Kilimanjaro. World-renowned for its hypnotic trichroic shifting between royal velvet blue, deep violet, and subtle red flashes.
Tourmaline: The Prism Spectrum
Showcasing a spectrum of color—from bi-color watermelon crystals to intense forest greens and sunset pinks. Excellent hardness and crystalline fire make it a masterpiece stone.
Tsavorite: The Green Fire
Named after the wild expanse of Tsavo National Park. Tsavorite is a rare green grossular garnet possessing high refractive brilliance and intense natural color clarity requiring zero enhancement.
Spinel: The Undiscovered Royal
Legendary Mahenge Spinels display electric neon-pink and fiery scarlet shades. Naturally clean and untreated, they stand among the most sought-after collector gems globally.
