Chrome diopside is a green gemstone that belongs to the pyroxene mineral group. It is primarily composed of magnesium, iron, and chromium, which gives it its vibrant green color. This gemstone is often found in metamorphic rocks and is mainly sourced from regions like Russia and Myanmar. Due to its striking appearance, chrome diopside is popular in jewelry, although it is less durable than other gemstones like emerald or sapphire. It has a hardness of 5.5 to 6 on the Mohs scale, making it suitable for use in earrings and pendants but less ideal for rings that experience daily wear.
