An emerald-green variety of grossular garnet, tsavorite is one of the most popular and expensive varieties of garnet. Suitable for any type of jewelry, tsavorites can be faceted into many designs.
Tsavorite Garnet Value
Clean, quality tsavorite, rough or faceted, isn’t difficult to find. Stones up to one carat are common. However, pieces over two carats are rare, and the price per carat jumps dramatically at that size. Stones with deep green, emerald-like color will command the highest prices.
Usually none in ultraviolet light (UV). Some specimens may fluoresce weakly golden yellow under shortwave (SW) or longwave (LW) UV, yellowish green or pink under SW UV, or orangish under LW UV. All massive material glows orange in X-rays, as do many faceted gems.
A trace of almandine garnet may produce a faint iron spectrum. A trace of Cr may produce a chrome spectrum in green grossular varieties. Massive grossular may show a weak line at 4610 or a band at 6300. Green, massive grossular from Pakistan shows a line at 6970 (weak) with weak lines in the orange, plus a strong band at 6300 and diffuse lines at 6050 and 5050.
Although named after the Tsavo East National Park in Kenya, tsavorite (sometimes called tsavolite) was first discovered in Tanzania in 1967. This gemstone became popular via a marketing campaign by Tiffany & Co. in the 1970s.
Clean tsavorites over one carat are rare. However, in 2006, a crystal weighing 925 cts (185 g) was discovered in Tanzania. It yielded an oval, brilliant step-cut 325-ct gem, likely the largest clean specimen ever discovered.
Although generally clean, some tsavorites do contain inclusions. Gems with fluid inclusions shouldn’t be cleaned with mechanical systems or exposed to extreme heat. Instead, use warm water, detergent, and a soft brush. (This advice applies to garnets in general). Consult our gem care guide and jewelry cleaning guide for more information.
