Discovered in 1967 near the border of Kenya and Tanzania, tsavorite is a stunning, emerald-green variety of grossular garnet named after the Tsavo National Park by Tiffany & Co. Its captivating, forest-green body color is driven by trace amounts of chromium and vanadium, producing a saturation so intense that fine specimens can easily rival the finest emeralds. However, unlike emeralds, tsavorite boasts a significantly higher refractive index and dispersion, giving it superior brilliance and sparkle without the need for routine oil or fracture treatments. Highly resistant to everyday wear due to its solid hardness, this ultra-rare East African gem has become a modern favorite for collectors seeking a completely natural, deeply radiant, and ethically sourced green stone.
