Tsavorite: Africa’s Vibrant Green and One of the Rarest Gemstones on Earth
At Shimansky, we are passionate about sharing the beauty and wonder of Africa’s rarest treasures. Among them is Tsavorite, a striking green gemstone that rivals emerald in color but stands alone in clarity, brilliance, and rarity. Discovered within the ancient earth of East Africa in 1967 , tsavorite is over 200 times rarer than emerald, yet remains one of the best-kept secrets in the world of fine gemstones. Unlike many stones that are enhanced or treated to appear more beautiful, tsavorite is naturally brilliant requiring no heat, no oil, and no disguise. What you see is what nature created. Its vivid green hues, remarkable clarity, and impressive durability make it one of the most extraordinary gems we work with at Shimansky.

A Rare Discovery Born in Africa
The story of tsavorite begins in the rugged, mineral-rich terrains of East Africa in the late 1960s. Hidden within the earth for over 500 million years, the gemstone was uncovered in the border regions between Tanzania and Kenya, embedded within ancient geological formations that few had explored. What followed was one of Africa’s most significant gemstone discoveries. The vibrant green garnet caught the attention of gem experts due to its unrivalled color, durability, and brilliance. But tsavorite was not only beautiful - it was also rare. Its deposits are limited to very specific geological conditions found only in a few places on earth. Most commercial supply still comes from carefully mined deposits in Kenya and Tanzania, making each gem a true piece of the African continent.

Natural Brilliance, No Enhancements
Tsavorite is a member of the garnet group, specifically the green grossular garnet. Its stunning color comes from trace amounts of vanadium and chromium, and unlike other green stones, its brilliance comes naturally. No heat treatment, no oiling - just pure, untouched beauty straight from the earth. With a Mohs hardness of 7 to 7.5, tsavorite is perfectly suited for daily wear, offering both strength and beauty. Its optical properties including high refractive index and vibrant fire give it a radiance that holds its own next to diamonds and other precious stones. Perhaps most notably, tsavorite often forms with exceptional clarity, making visible inclusions a rarity rather than the norm. This makes it an ideal choice for connoisseurs who appreciate gemstones that shine without intervention.

A Future Rooted in Ethical Practices
At Shimansky, we understand that true luxury comes with responsibility. That’s why we are committed to ensuring our gemstones are ethically sourced, including tsavorite. Our direct relationships with trusted sources in East Africa ensure full traceability from mine to masterpiece. Because tsavorite is mined in relatively small-scale operations, it allows for more oversight and greater accountability. We take pride in working with partners who respect the environment, uplift local communities, and protect the integrity of the land. As global interest in tsavorite continues to grow, its scarcity remains ensuring that each stone retains its value, uniqueness, and mystique. It is a gem for those who appreciate authenticity, rarity, and the true story behind the sparkle.

A combination of nature’s most precious colours.
