Type
Raw Gold (Ore/Nugget/Specimen)
Purity
Variable; typically contains 20K-24K natural gold flakes (83%-99.9% fineness) within a non-precious mineral matrix.
Gold Type
Natural Gold within Host Rock (Yellow Gold highlights in Grey/White Quartz/Schist)
Weight
150g - 250g (estimated total weight of the specimen including host rock)
Description
A raw, unrefined gold ore specimen featuring visible metallic inclusions within a dense, multi-mineral host rock. The specimen exhibits a flat, disc-like shape with a weathered, rounded edge suggesting it may have been tumbled in a riverbed (alluvial) or heavily weathered near the surface. The surface displays a characteristic 'pay dirt' appearance with sparkling inclusions that require professional assay to distinguish between native gold and 'fool's gold' (pyrite).
Key Features
Visible metallic luster, high density common to auriferous rock, natural river-worn or weathered texture, and mixed mineral composition.
Color & Finish
Natural earthy tones with metallic yellow flecks; surface is rough, unpolished, and weathered (natural alluvial or outcropping patina).
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
80mm x 55mm x 20mm (Hand-sized specimen)
Gemstones & Inlays
Crystalline Quartz, Mica, and possible Sulfide minerals (Pyrite or Arsenopyrite) acting as the matrix.
Clasp & Closure
Not applicable (Natural stone)
Chain & Links
Not applicable (Natural monolithic structure)
Craftsmanship Details
Natural geological processes; no human craftsmanship present. The 'finish' is a result of tectonic pressure and environmental erosion.
Authentication Indicators
Metallic luster, non-uniform gold distribution, high specific gravity relative to size. Red flag: Visible crystal faces on yellow parts could indicate pyrite rather than malleable gold.
Origin & Maker
Natural geological formation; commonly found in 'Mother Lode' regions or alluvial deposits.
Era & Period
Geological formation (Archean to Cenozoic depending on origin region)
Age Estimate
Millions of years (Natural formation)
Cultural Significance
Represents the 'Gold Rush' era heritage and the fundamental source of wealth for human civilizations for millennia.
Condition Notes
Natural/Raw; exhibits environmental weathering, surface abrasions, and mineral oxidation consistent with geological specimens. Grade: Raw Specimen.
Value Estimate
$50 - $300 (Primarily as a collector specimen; 'melt value' is negligible unless high-grade gold content is proven via assay).
Care & Maintenance
Keep dry to prevent oxidation of sulfide minerals; clean only with distilled water and a soft brush; do not use harsh chemicals or ultrasonic cleaners which may break the rock matrix.
Similar Items
Gold-bearing Pyrite (Fool's Gold), Chalcopyrite, or gold-plated river stones. Differences include weight/density, malleability, and chemical reactivity.
Interesting Facts
Most 'gold nuggets' found by prospectors are actually part of a larger ore body like this; less than 2% of the world's gold is found in large, solid nugget form.
