Which element is responsible for the green color in Tsavorite garnet?

The green color in Tsavorite garnet is primarily attributed to chromium. This element is known for its ability to impart a vibrant green hue to various gemstones, and in the case of Tsavorite, it enhances the stone's overall brilliance and saturation. Chromium's presence in the crystal lattice of the garnet results in strong absorption of certain wavelengths of light, which allows the intense green color to emerge.

For Tsavorite, it's especially important because color is one of the key quality factors that significantly affects its value. The finest examples of Tsavorite display a rich, deep green color largely due to the optimal amount of chromium, complemented by the garnet's inherent qualities that enhance its visual appeal. This makes it distinguishable and desirable among other green gemstones.

Other elements, such as vanadium, cobalt, and iron, play different roles in the coloration of various gemstones, but for Tsavorite garnet specifically, chromium is the critical element that defines its green color.
