Diopside is named after Greek word for "double appearance" because of its crystal shape. Although Diopside occurs in a variety of colors, the green color is the most common form. A purple type known as Violane is occasionally used as a gemstone, and Star Diopside is very dark green to black. But the form of this stone that puts this gemstone on the map is the deep green Chrome Diopside form. Chrome Diopside in limited quantity is known from several localities, first discovered in Siberia in 1988 and then, Pakistan has also become a significant producer of Chrome Diopside. Deep green colour combined with transparency give a stone more value. Except in lighter coloured stones, the faceting of larger cuts is generally avoided because the deep green color tends to make its tone too black. Careful cutting is also necessary in larger stones to improve brilliance.

VirtuesDiopside is said to open up the feminine side of one's being. It is also called ‘the logic stone', as it is believed to help with analysis and logic, as an assistant to learning.
SpecificationsDiopside is a mineral found in igneous rock formations and meteorites. Diopside's rich, vibrant greens rival the beauty of emerald. Its colour variations range from a vivid, bright green to a dark green that can appear almost black. It also possesses excellent ‘pleochroism', which means it can be viewed from many different angles and appear to have a variety of colours.
HistoryDiopside is one of the rare gemstones whose history has truly just begun. The world first heard about it in 1988, when rumours of a stunning green gem emerged out of northern Siberia.
Due to restrictions caused by the Cold War, access to the area was very limited. Other very minor deposits have since been discovered, but the mines in the Republic of Sakha in Siberia are the only commercially viable. The supplies of the crystal have thus remained very narrow, because of the risky weather conditions surrounding these mines, where production is sporadic due to extreme winters that last more than eight months.
