Diopside is most often bottle-green in color, though it can be found colorless, brown, black, violet-green, and blue colors. The two most well-known varieties of Diopside are the emerald-green like Chrome Diopside and the Black Star Diopside. Chrome Diopside offers a beautiful rich green color at low cost, in fact, it is the most affordable of the pure rich-green colored gemstones. It is most readily available in small sizes as the color becomes too dark in larger sizes. Black Star Diopside is black in color with occasional shades of green, and exhibits a star like phenomenon known as Asterism. These stones contain inclusions in the form of needles that align to produce a white 4-rayed star. It is unique in this sense because it is the only gemstone to exhibit a 4-rayed star. There is also a rare blue variety of Diopside, known as Violane that is found in some localities in Italy.

The value of Diopside will depend on the variety chosen. Eye-clean Chrome Diopsides exhibiting a rich, even green color will be at the higher end of the value spectrum. The value of Black Star Diopside is judged primarily by taking into account the sharpness of the displayed star.

Chrome Diopside is the variety most often seen faceted, whereas Violane is generally used for beads and inlay work. Black Star Diopside are cut into Cabochons, the only shape that allows the stone to display the beautiful asterism, or star.
