Breyite is a high pressure calcium silicate mineral (CaSiO3) found in diamond inclusions.[3][4] It is the second most abundant inclusion after ferropericlase, for diamonds with a deep Earth origin.[5][4] Its occurrence can also indicate the host diamond's super-deep origin. This mineral is named after German mineralogist, petrologist and geochemist Gerhard P. Brey.
