What is the primary coloring agent for Tsavorite garnet?

The primary coloring agent for Tsavorite garnet is chromium. This element is responsible for the vivid green hues that characterize Tsavorite, enhancing its saturation and overall brilliance. Chromium is a well-known chromophore in many gemstones, and in the case of Tsavorite, it creates that distinctive emerald-like appearance. The presence of chromium can also contribute to the depth of color, making Tsavorite one of the most sought-after varieties of garnet.

While other elements, such as iron and manganese, can affect the color of garnets in general, they do not provide the same intense green coloration found in Tsavorite. Therefore, the specific role of chromium in imparting color to this garnet type makes it the correct choice for identifying its primary coloring agent.
