Diopside is a calcium magnesium silicate belonging to the pyroxene group of minerals. It is a major rock formation in volcanic rocks and is also found in meteorites. Diopside is derived from the Greek words "dis" (double) and "opus" (face). This means the double form, which refers to the prism-oriented method of the crystal. The dioxide may appear as a colorless crystal, but there are Diopside crystals of brown, yellowish-brown, blue-green, greenish-black, gray, green, white, or lavender.
It usually comes in two forms.
- Chrome Diopside:- Also Known As Siberian Emerald or Green Dioxide
- Star Diopside:- The black type of diopside is known as the black star diode because it displays a star in the crystal.
