Millerite is a metallic nickel sulfide mineral that forms as cylindrical, prismatic crystals and granular masses with a bright to metallic luster. Its color ranges from brassy to steel-gray, and it often occurs in dense aggregates or as clean, reflective crystals embedded in mafic rocks and sulfide-bearing veins. The mineral can display a lustrous surface and a relatively high refractive quality that catches the eye in hand specimens or cabinet-sized samples.

About Millerite
Notable specimens come from classic localities in the United States and Europe, where Millerite has been described in sulfide-rich environments and hydrothermal settings. It commonly occurs with other nickel sulfides and associated minerals in ultramafic rocks and metamorphosed sulfide deposits, giving collectors material that is both historically significant and scientifically interesting. Its compact habit and bright metallic finish make it prized for display as a representative nickel sulfide, often cut or carved for study and appreciation.
