Raw Natural Gold-Bearing Specimen in Gossan/Ironstone Host Rock
Raw Gold (Nugget in Matrix / Ore) · Natural Native Gold; rich yellow hue typical of alluvial or lode deposits with high silver/copper trace purity.
Purity: Estimated 20K-23K (83%-96%) for the visible gold flakes; the specimen as a whole is mineral ore.
Type
Raw Gold (Nugget in Matrix / Ore)
Purity
Estimated 20K-23K (83%-96%) for the visible gold flakes; the specimen as a whole is mineral ore.
Gold Type
Natural Native Gold; rich yellow hue typical of alluvial or lode deposits with high silver/copper trace purity.
Weight
Estimated 15-40 grams for the total specimen; total gold content requires specific gravity testing to determine.
Description
This is a rugged, raw geological specimen featuring visible 'leaf' or 'wire' gold embedded within a secondary iron oxide matrix known as gossan. The contrast between the brilliant yellow precious metal and the dark, earthy tones of the ironstone makes for a compelling collector's piece. Unlike processed bullion, this item retains its natural crystalline or amorphous form as it was extracted from the earth.
Key Features
High-contrast color zones; visible native gold wires or flakes; iron-rich 'gossan' host rock which is a classic indicator of deep-seated mineral veins.
Color & Finish
Vivid buttery yellow gold inclusions against a dark reddish-brown, ochre, and hematite-crusted ironstone surface.
Hallmarks & Stamps
None. As a raw geological specimen, it lacks man-made stamps or hallmarks.
Dimensions Estimate
Approx. 30mm x 25mm x 15mm; roughly the size of a large grape or small walnut.
Gemstones & Inlays
Natural mineral inclusions; potentially Quartz, Hematite, Limonite, and Goethite.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; jagged, natural fracture surfaces on host rock.
Craftsmanship Details
Natural geological crystallization; no human craftsmanship; the 'finish' is a result of natural erosion and mechanical extraction from a mine or creek bed.
Authentication Indicators
Sectility (gold will dent, not shatter); high luster even in shade; uneven, non-repetitive natural crystalline structure; absence of 'fool's gold' (pyrite) cubic symmetry.
Origin & Maker
Natural Earth formation; likely from an orogenic gold deposit (e.g., Australia, Nevada, or Western Africa).
Era & Period
Modern Discovery; geological age of formation likely millions of years (Archean or Proterozoic).
Age Estimate
Geological formation: millions of years; Recovery date: Contemporary.
Cultural Significance
Represents the 'Gold Rush' archetype; symbolizing the raw wealth and prospecting heritage of the 19th-century mining booms.
Condition Notes
Grade: Raw/Field Recovered. Shows natural weathering, fracture lines from extraction, and minor dirt/soil accumulation in crevices.
Value Estimate
Specimen Value: $150 - $500 depending on total gold weight vs. rock weight. Primarily valued for its aesthetics as a mineral specimen rather than pure melt value.
Care & Maintenance
Clean only with distilled water and a soft brush; avoid acids (unless removing iron); store in a padded gem jar to prevent 'shedding' of gold flakes.

Interesting Facts
Most gold found in the world is microscopic; finding 'visible gold' in host rock like this occurs in less than 1% of gold-bearing ore samples.
