Natural Native Gold in Quartz Matrix with Oxidized Sulfides
Raw Gold (Nugget/Ore/Specimen) · Natural Native Gold Yellow
Purity: Likely 20K to 23K (83% - 96% fine gold content) based on native specimen color
Type
Raw Gold (Nugget/Ore/Specimen)
Purity
Likely 20K to 23K (83% - 96% fine gold content) based on native specimen color
Gold Type
Natural Native Gold Yellow
Weight
Indeterminate based on visual; high specific gravity indicates gold presence in matrix
Description
A stunning macro view of a high-grade gold ore specimen. The piece features vibrant ribbons of native gold embedded within a fractured milky quartz matrix, accompanied by secondary mineralization that suggests a complex hydrothermal origin. The interplay of the metallic yellow gold against the greens of copper oxidation and the whites of quartz creates a dramatic aesthetic appeal for mineral collectors.
Key Features
Crystalline structure of native gold, visible malachite staining, hydrothermal quartz fractures
Color & Finish
Deep, rich buttery yellow metallic luster for gold; milky white quartz and green/red oxidation
Hallmarks & Stamps
None; natural geological specimen
Dimensions Estimate
Macro close-up; specimen likely 1-3 inches based on crystal texture
Gemstones & Inlays
Host matrix of crystalline Quartz with secondary Malachite (green) and Iron oxides (red/brown)
Clasp & Closure
Not applicable; raw mineral specimen
Chain & Links
Not applicable; irregular natural crystalline boundaries
Craftsmanship Details
Natural geological formation via hydrothermal deposition in fault zones
Authentication Indicators
Metallic luster consistent with gold; lack of cleavage in yellow sections distinguishes it from pyrite
Origin & Maker
Likely Western United States, Australia, or Canada (Natural Mother Lode origin)
Era & Period
Contemporary Geological Discovery (Natural mineral formation)
Age Estimate
Millions of years (Geological formation); recently extracted
Cultural Significance
Gold-bearing quartz specimens fueled the historic Gold Rush eras in California and the Klondike.
Condition Notes
Natural raw state; surface presents characteristic oxidization of associated sulfides (pyrite/chalcopyrite)
Value Estimate
Collector value exceeds melt value; depends on 'gold-to-matrix' visual ratio and provenance.
Care & Maintenance
Keep dry; clean only with distilled water and a soft brush; avoid acids that may dissolve secondary minerals.

Interesting Facts
Most gold is mined as microscopic particles; specimens with visible 'leaf' or 'wire' gold like this are rare and kept for display rather than smelting.
