Weight
15-25 grams total specimen weight (gold content significantly lower)
Description
A raw, unrefined gold specimen featuring visible flecks and small veins of native gold embedded within a dark, dense matrix of host rock. The gold exhibits a distinct, high-luster metallic sheen and a heavy saturation of color compared to the earthy, textured background of the stone.
Key Features
Heterogeneous distribution of gold; jagged, irregular edges; visible crystalline structure in gold particles
Color & Finish
Brilliant buttery yellow metallic inclusions within a dark, weathered grey-green host rock
Hallmarks & Stamps
None; natural geological specimen
Dimensions Estimate
35mm length x 15mm width x 8mm thickness
Gemstones & Inlays
None; natural quartz or sulfide mineralization visible in host matrix
Clasp & Closure
Not applicable; raw specimen
Chain & Links
Not applicable; rough geological structure
Craftsmanship Details
Natural geological formation through hydrothermal or alluvial processes; no human craftsmanship present
Authentication Indicators
Sectile nature of yellow particles (gold can be cut or dented, while pyrite shatters); lack of cleavage in metallic parts; density relative to size
Origin & Maker
Unknown; likely an alluvial or hard-rock mining prospect
Era & Period
Geological Formation (Millions of years old)
Age Estimate
Natural formation; hundreds of millions of years
Cultural Significance
Represents the 'Gold Rush' heritage and the primary form of wealth extraction throughout human history
Condition Notes
Natural raw state; surface presents environmental weathering and typical abrasive wear from water or soil
Value Estimate
Collector value $50-$150 USD based on visible gold; melt value is negligible until refined
Care & Maintenance
Clean only with distilled water and a soft brush; avoid harsh chemicals that could dissolve the host stone; store in a padded specimen box

Interesting Facts
Most gold is found as microscopic particles; visible specimens of this size in host rock are relatively rare and prized by mineral collectors
