Welcome to SuchenGems!

Tsavorite is a rare, vibrant green gemstone from the grossular garnet family, prized for its intense color, which ranges from green to blue-green. Colored by trace amounts of chromium or vanadium, it is often compared to emerald for its beauty, but it is generally more durable and has a high refractive index that gives it great brilliance. Tsavorite is 100% natural and typically only requires cutting and polishing, unlike many other colored stones that are treated to enhance their color.
