Tanzanite is a truly extraordinary gemstone, found in just one place on Earth—northern Tanzania, at the base of Mount Kilimanjaro. Its unique geological origins and mesmerizing color have made it a sensation in the world of fine gemstones.
In 1967, a Maasai herdsman stumbled upon striking blue-violet crystals among the rocky terrain. Initially mistaken for sapphires, these gems were later identified as a rare variety of zoisite, never before seen in such vibrant hues.
Recognizing its immense potential, Henry Platt, then-president of Tiffany & Co., named the stone Tanzanite in honor of its country of origin. With Tiffany’s backing, a major marketing campaign introduced this dazzling gemstone to the world. Platt is famously called tanzanite the most beautiful blue gemstone discovered in the past 2,000 years. By the late 1990s, it had become one of the most sought-after colored gemstones, admired by jewelers and collectors alike.
Tanzanite is prized for its deep blue-violet hue and exceptional pleochroism—a unique optical effect that causes the stone to shift colors depending on the viewing angle. As it moves, tanzanite reveals shades of rich blue, vibrant violet, and even subtle hints of green.
To enhance its signature color, most tanzanites undergo low-temperature heat treatment (450–600°C) to remove brownish undertones. This treatment is widely accepted and does not affect the stone’s value.
Tanzanites are most commonly cut into oval and cushion shapes, which best display their dynamic play of color. Large, high-quality tanzanites over 8–10 carats are still available, but with the world’s only known deposit becoming increasingly scarce, the stone’s value is expected to rise significantly in the future.
Ksenia Podnebesnaya frequently incorporates tanzanites into SORA’s jewelry designs. You can find stunning rings and earrings featuring this exceptional gemstone in the Daily Gems, Metropolis, and Colorful Dew collections.
