This igneous rock has olivine, pyroxine, feldspar, and possibly diamond. The rock’s surface is a light green because of the olivine but leaves a white streak because of the feldspar. It has a Mohs-6-7 rating which means it scratches glass but doesn’t scratch steel or anything harder than that. If this rock were to be compressed some of the minerals in it would create emeralds.
