The compositions of peridotite nodules found in certain basalts are of special interest along with diamond pipes ( kimberlite ), because they provide samples of earth's mantle brought up from depths ranging from about 30 km to 200 km or more. Olivines (those from earth, not from outer space) form in the earth's mantle. Occasionally it's also been seen having formed in large mass structures. Peridotite is a rock type that is more representative of earth’s mantle than of the crust. The green colors of the gem depend on the structure of the iron contents. Web nevertheless, gemologists today no longer use this term. Its chemical composition includes iron and magnesium, and iron is the cause of its attractive yellowish green colors.
