Raw Gold Bearing Quartz in Basalt Matrix Specimen
Raw Gold · Native Gold Vein in Dark Host Rock
Purity: Natural Native Gold (Estimated Variable Purity 20K to 24K)
Type
Raw Gold
Purity
Natural Native Gold (Estimated Variable Purity 20K to 24K)
Gold Type
Native Gold Vein in Dark Host Rock
Weight
Cannot be precisely determined from visual inspection alone, estimated moderate hand sample weight
Description
This specimen features a dark, fine-grained host rock split or exposed to reveal a striking, thin mineral vein running across its face, accompanied by warm, oxidized golden staining throughout the matrix. It represents a classic prospector's hand sample showing hydrothermal vein formation where gold-bearing fluids filled fractures in the surrounding country rock.
Key Features
Distinct linear vein structure, contrasting dark host rock, and natural weathering oxidation spots indicating potential gold mineralization
Color & Finish
Dark grey to black host rock with naturally occurring golden-brown oxidation patches and a visible thin native gold or quartz-gold vein running horizontally
Hallmarks & Stamps
None present, as this is a natural geological specimen directly from the earth
Dimensions Estimate
Hand-sized specimen, roughly 3 to 4 inches across
Gemstones & Inlays
Natural quartz vein mineralisation containing native gold traces embedded in a dark mafic or metamorphic host rock matrix
Clasp & Closure
Not applicable
Chain & Links
Not applicable
Craftsmanship Details
Purely natural geological processes including hydrothermal activity, mineral deposition, and tectonic fracturing
Authentication Indicators
Natural matrix structure, irregular fracture lines, and absence of human-made hallmarks or tool finishes; professional assaying or specific gravity testing required to confirm gold content
Origin & Maker
Natural Geological Origin, Earth Formed
Era & Period
Geological Formation (Prehistoric / Natural)
Age Estimate
Geological age, hundreds of thousands to millions of years old
Cultural Significance
Raw gold ore specimens are the tangible beginning of all human monetary history, jewelry, and luxury artifacts, representing the ultimate source of wealth generation and exploration
Condition Notes
Rough, unworked geological condition with natural fracture surfaces and weathered mineral oxidation
Value Estimate
Valued primarily as a mineral specimen and educational or decorative display piece; actual precious metal melt value is negligible until refined or verified by assay
Care & Maintenance
Keep dry and store carefully in a cushioned display case to prevent flaking of delicate matrix material or loss of loose mineral grains

Interesting Facts
Most gold on Earth is found locked away in quartz veins within bedrock rather than as loose nuggets in streams. Prospectors historically searched for float samples like this to trace back to primary vein deposits.
