Description
A raw, unrefined gold nugget specimen showing typical lode characteristics. The item exhibits a jagged, crystalline structure with significant host rock or mineral inclusions, suggesting it was found near the primary source rather than water-worn in a riverbed. Its surface presents a mix of dark oxidation and bright native gold metallic luster.
Key Features
Crystalline structure, heavy specific gravity, uneven surface with vugs (cavities), and lack of synthetic tool marks.
Color & Finish
Dull metallic luster with localized bright yellow glints; natural weathered and encrusted finish
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
Approximately 12mm x 15mm x 8mm

Possible quartz or iron-oxide inclusions; no faceted stones
Clasp & Closure
Not applicable (Natural nugget)
Chain & Links
Not applicable (Solid geological formation)
Craftsmanship Details
Natural geological formation; no human craftsmanship present.
Authentication Indicators
Characteristic uneven luster, high density (implied), and lack of crystalline 'flaking' seen in Pyrite. Note: Streak test or XRF recommended to rule out Chalcopyrite.
Origin & Maker
Natural alluvial or lode deposit; Maker: Nature
Era & Period
Geological formation (Holocene or older)
Age Estimate
Formed millions of years ago; recently recovered
Cultural Significance
Represents the 'Gold Rush' heritage and the primary form of wealth that drove global exploration.
Condition Notes
Grade: Raw Specimen. Features natural surface abrasions and mineral encrustations typical of raw gold ore.
Value Estimate
$200 - $550 USD (Based on gold spot price plus a 10-30% premium for specimen rarity)
Care & Maintenance
Clean with soft brush and distilled water; avoid harsh chemicals that may react with mineral inclusions; store in a padded specimen box.
