Generally 20K to 23K (83%-96%)
Gold Type
Natural Native Gold Alloy (Silver/Copper traces)
Weight
3 to 8 grams (estimated by scale against finger ridges)
Description
A dense, rounded natural gold nugget exhibiting the characteristic smooth yet pitted texture of alluvial gold. This specimen shows a vibrant yellow luster typical of high-purity native gold, with dark mineral inclusions nestled in the crevices, indicating it was likely recovered from a riverbed or stream.
Key Features
High density, irregular water-worn shape, absence of crystal structure, characteristic buttery yellow color
Color & Finish
Deep buttery yellow with dark iron oxide and quartz inclusions; naturally water-worn and tumbled finish
Hallmarks & Stamps
None (Natural specimen)
Dimensions Estimate
Approximately 12mm x 10mm x 6mm (Sub-centimeter scale)
Gemstones & Inlays
None; natural quartz or ironstone host rock inclusions likely present
Clasp & Closure
None (Raw specimen)
Chain & Links
None (Solid irregular mass)
Craftsmanship Details
None (Natural geological formation; no human manipulation visible)
Authentication Indicators
Sectility (if tested), high density, lack of distinct cleavage, specific yellow hue that does not tarnish like pyrite (fools gold). Red flag: heavily iron-stained basalt rocks can sometimes mimic this appearance.
Origin & Maker
Natural placer deposit; Earth-formed via hydrothermal or alluvial processes
Era & Period
Geological / Holocene (Formed over millions of years)
Age Estimate
Geological age (Millions of years); Recovery date unknown
Cultural Significance
Nuggets have triggered global migrations and gold rushes, symbolizing the ultimate 'strike it rich' discovery in human history.
Condition Notes
Natural Raw state; weathered surface with significant mineral staining and minor abrasions consistent with stream transport.
Value Estimate
Spot gold value + 10-30% specimen premium (if verified authentic gold content)
Care & Maintenance
Clean with mild soapy water and a soft brush; avoid harsh chemicals that may react with host rock inclusions; store in a padded display case.

Interesting Facts
Most gold is found as microscopic flakes; nuggets large enough to be held represent less than 2% of the world's total gold production.
