A magnesium iron silicate and the primary component of Earth's upper mantle, common in the subsurface but quick to weather at the surface. Its clear green gem variety is peridot, and it also serves industrial uses such as metalworking processes.

Facts
Formation ClassNesosilicate, crystallizing early and at high temperature from mafic and ultramafic magma; the dominant mineral of the Earth's upper mantle. 1 Chemical Formula Hardness (Mohs)Commonly cited range is 6.5 to 7.0 on the Mohs scale; 6.5 is used here. Classification

Dunite is composed of at least 90 percent olivine by definition, the most olivine-rich common rock.
Komatiite is defined by its high magnesium content, expressed as abundant olivine, often in spinifex texture.
Olivine is the defining, essential mineral of peridotite.

Classified As
Entity-backed identity for the material classification this material already carries as an enum fact, pointing at the class subcategory of the same name. The enum fact itself stays on the entity unchanged.
Crystallizes In System
Entity-backed identity for the crystal-system enum value this material already carries, resolved to an earth concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The crystal-system fact itself stays on the material unchanged.
