Gold Type
Native Gold within Matrix (likely associated with Iron Sulfides)
Weight
3 to 8 grams (estimated based on visual size relative to fingertips)
Description
This is a raw mineral specimen containing metallic sulfides often associated with gold. The piece displays a rugged, angular morphology with a characteristic metallic luster. Note the iridescent purples and greens which suggest the presence of Chalcopyrite. While visually 'gold-colored,' such specimens are frequently 'Fool's Gold' (Pyrite) or gold-bearing ore rather than a solid nugget of native gold.
Key Features
Angular crystal structure, iridescent surface oxidation (tarnish), metallic micro-fractures, and lacks the malleability of high-purity native gold.
Color & Finish
Brass-yellow to pale bronze with iridescent tarnish. Surface is rough, crystalline, and fractured with a metallic luster.
Hallmarks & Stamps
None. As a raw geological specimen, it lacks man-made hallmarks or purity stamps.
Dimensions Estimate
Approximately 15mm x 10mm x 8mm
Gemstones & Inlays
None. Contains natural mineral inclusions of Pyrite (Fool's Gold) and likely Chalcopyrite, indicated by the iridescent 'peacock' tarnish.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; raw mineral specimen with jagged structural fractures.
Craftsmanship Details
Natural crystalline growth. No human craftsmanship present; edges are defined by geological cleavage and fracture planes.
Authentication Indicators
Red flags for pure gold: Visible brittle fractures and iridescence common in sulfides. Native gold is typically more rounded (if alluvial) or soft/malleable. This appears to be a mineral compound like Arsenopyrite or Pyrite.
Origin & Maker
Unknown geographic origin; likely from a hydrothermal quartz vein or volcanic deposit. Maker is Earth/Nature.
Era & Period
Geological (Pre-human). This is a natural geological formation, not a manufactured piece.
Age Estimate
Millions of years old, based on typical geological formation cycles for gold-bearing sulfides.
Cultural Significance
Represents the 'Gold Rush' era of prospecting where miners sought 'lode' deposits in hard rock. Historically significant as the primary source of wealth for many civilizations.
Condition Notes
Natural raw state. Surface shows 'shattering' and oxidation typical of extracted ore. Grade: Mineral Specimen.
Value Estimate
Nominal collector value ($5–$25) as a mineral specimen. Melt value is likely negligible as it is ore-grade rather than a pure metal nugget.
Care & Maintenance
Keep dry to prevent further oxidation of sulfide minerals. Clean only with distilled water and a soft brush; avoid acids which may dissolve the matrix.
Similar Items

Interesting Facts
The majority of the world's gold is actually extracted from ore that looks exactly like this, where the gold is invisible to the naked eye and requires chemical leaching to recover.
