2.1" Pyrope, Forsterite, Diopside & Omphacite Association - Norway

This is a gorgeous association of pyrope garnets, forsterite, diopside and omphacite that was collected from Gusdal, Norway (likely from the Gusdal Olivine Pit). The pyrope garnets are red-magenta in color and are peppered throughout a green matrix that's composed of forsterite, diopside and omphacite. This mineral association is also known as pyrope-olivine-websterite. This specimen has been left in its rough form and comes with an acrylic display case.

Diopside is a pyroxene mineral with the chemical formula MgCaSi₂O₆. It is often found as small green crystals within metamorphic and igneous rocks, though it can vary in color including yellow, brown, and black. It is an important indicator rock when searching for deep-source volcanic pipes that may or may not contain diamonds. Geologists searching for these pipes often look for diopside crystal fragments, since they form in nearly the same atmospheric conditions and locations as diamonds. Diopside with deep green coloration is known as chrome diopside.
