Diopside is a mineral found in basic and ultrabasic rocks such as gabbro and peridotite. Diopside forms short to long prismatic crystals, but it is also found as columnar, lamellar, or granular mineral aggregates. Gemstone-quality diopsides are transformed into precious stones. Among these, Russian chrome diopside is the most notable. Today we are offering at auction a beautiful, large, intense green rough specimen. Backlit photos show the green color explosion!
