Mineral & Geological Classification – Galena
Galena is a lead sulfide mineral with the chemical formula PbS. It is the principal ore of lead and belongs to the sulfide mineral group. Galena crystallises in the isometric (cubic) crystal system, forming some of the most recognisable cubic crystals in mineralogy.
Mineral Name: Galena
Chemical Formula: PbS
Mineral Group: Sulfide
Crystal System: Isometric (Cubic)
Hardness: 2.5–2.75 on the Mohs scale
Lustre: Metallic
Colour: Lead-grey to silver-grey
Cleavage: Perfect cubic cleavage in three directions
Galena is known for its bright metallic sheen and sharply defined cubic crystals. Even when broken, the mineral often reveals smaller cubes due to its perfect cleavage along three perpendicular planes.
Geological Formation & UK Occurrence
In the United Kingdom, galena is commonly found in hydrothermal vein deposits associated with historic mining regions such as Cornwall, Derbyshire, Cumbria and the Pennine Orefield. These mineral veins formed when metal-rich hydrothermal fluids migrated through fractures and fissures in the host rock.
As temperatures and pressures changed, dissolved lead and sulfur combined to precipitate lead sulfide within open cavities. Over time, well-formed cubic crystals developed where space allowed free growth.
Galena frequently occurs alongside:
-
Quartz
-
Fluorite
-
Calcite
-
Sphalerite
-
Chalcopyrite
-
Baryte
The association of these minerals reflects multi-stage hydrothermal activity linked to tectonic movements and, in some regions, granite intrusions.
Crystal Characteristics & Notable Traits
This Galena specimen may display:
-
Well-defined cubic crystal structure
-
Bright reflective metallic surfaces
-
Stepped cubic growth patterns
-
Natural matrix attachment
The mineral’s high specific gravity gives it a noticeable weight relative to its size. Fresh crystal faces show a silver-grey metallic shine, while minor natural oxidation may create subtle surface variations.
The cubic symmetry and mirror-like surfaces make galena one of the most visually striking metallic minerals.
Geological Importance & Collectibility
Galena has played a major role in British mining history as the primary source of lead. Specimens from UK localities carry both geological and historical significance, representing centuries of mineral extraction and industrial development.
Collectors value galena for:
-
Its textbook cubic crystal habit
-
Strong metallic lustre
-
High density
-
Association with classic British ore fields
This specimen is suitable for mineral cabinets, educational collections and collectors of metallic sulfide minerals.
As a genuine natural specimen, it displays unique crystal arrangements and surface characteristics shaped by its formation environment. The photograph shows the exact specimen you will receive.
Authenticity & Presentation
This Galena crystal from the UK has been carefully chosen for quality, crystal definition and presentation. Included with your purchase is a Certificate of Authenticity lifetime guarantee generic card confirming its genuine mineral status.
Combining classic cubic crystal geometry with historic British mineralisation, this Galena specimen offers mineral authenticity, geological interest and strong collector appeal in one carefully selected piece.
