Diopside is a monoclinic pyroxene mineral. Chrome diopside includes chromium, giving it a rich green color. Due to the deep forest-green color, it is sometimes referred to as Siberian emerald. Chrome Diopside in limited quantity can be found in several localities, but a large commercial quality deposit discovered in Siberia in 1988 made this gemstone readily available to the market. Since then, Pakistan has also become a significant producer of Chrome Diopside. Chrome Diopside is an affordable gemstone with an intense green color, rivaling the more expensive Tsavorite and Green Chrome Tourmaline. It is a relatively soft stone, with a Mohs hardness of 5.5–6.5, so should be treated with care. Clean with warm soapy water and a soft cloth. Chrome Diopside is associated with the heart chakra, and mystics say that it helps you open your heart to love, and be more connected to Gaia.
