Mineral & Geological Classification – Cinnabar

Cinnabar is a mercury sulfide mineral with the chemical formula HgS. It is the primary ore of mercury and crystallises in the trigonal crystal system.

Mineral Name: Cinnabar
Chemical Formula: HgS
Mineral Group: Sulfide
Crystal System: Trigonal
Hardness: 2–2.5 on the Mohs scale
Lustre: Adamantine to dull
Colour: Scarlet red to deep crimson

Cinnabar is instantly recognisable due to its vivid red colour, which can range from bright scarlet to darker red tones depending on crystal form and surface condition. Crystals may occur as well-formed rhombohedral shapes, granular aggregates or massive coatings within host rock.

The high refractive index of cinnabar can produce a bright, almost glowing surface under strong light. Its colour is natural and derives from the mercury-sulfur chemical composition.

Geological Setting – Lone Pine Mine, Republic Mining District

The Republic Mining District in Ferry County, Washington, is historically known for gold and associated hydrothermal mineralisation. Cinnabar from the Lone Pine Mine formed in low-temperature hydrothermal vein systems where mercury-rich fluids circulated through fractures in host rocks.

Cinnabar commonly develops in epithermal environments, often associated with quartz veins and other sulfide minerals. In such settings, mineralising fluids rise toward the surface and deposit mercury sulfide as temperatures and pressures decrease.

Associated minerals in similar deposits may include quartz, calcite, pyrite and other sulfides depending on local geochemical conditions. The Republic District’s complex structural geology provided pathways for mineral-bearing fluids, allowing cinnabar to crystallise within open fractures and cavities.

Crystal Characteristics & Notable Traits

Cinnabar from this locality may display:

• Bright red to crimson colouration

• Crystalline or granular surface texture

• Adamantine sheen on crystal faces

• Occurrence on contrasting pale matrix

In some specimens, cinnabar forms small, sharply defined crystals, while in others it appears as fine-grained coatings or masses within quartz veins. The intense natural red colour contrasts strongly with light-coloured host rock, enhancing display appeal.

Because cinnabar is relatively soft, crystal edges may show minor natural wear. Surface features and matrix attachment are part of the mineral’s geological formation and authenticity.

Geological Importance & Collectibility

Cinnabar is significant as the principal ore of mercury and as an indicator of epithermal hydrothermal systems. Specimens from documented localities such as the Lone Pine Mine are valued for both scientific and collector interest.

The Republic Mining District holds historical importance within Washington State mining history. Mineral specimens from this area represent classic American hydrothermal mineralisation.

This piece is suitable for mineral cabinets, educational collections or collectors specialising in sulfide minerals and United States localities. As a genuine natural specimen, it displays unique characteristics shaped by its formation environment. The photograph shows the exact specimen you will receive.
