Raw Natural Gold-Bearing Ore Nugget
Raw Gold / Gold-Bearing Quartz Specimen · Native Yellow Gold in Sulphide or Quartz Matrix
Purity: Estimated 18K to 23K (75-97% pure) for the native gold inclusions. Natural gold is rarely 24K and typically contains silver or copper alloys.

Purity
Estimated 18K to 23K (75-97% pure) for the native gold inclusions. Natural gold is rarely 24K and typically contains silver or copper alloys.
Gold Type
Native Yellow Gold in Sulphide or Quartz Matrix
Weight
3 to 7 grams (Estimated total mass of specimen)
Description
A raw, unrefined gold-bearing mineral specimen featuring visible flecks of native gold embedded in a dark, metallic-gray matrix. This 'specimen gold' represents the rawest form of the metal before it is smelted and refined for jewelry or bullion, showing the intense contrast between the precious metal and the surrounding ore.
Key Features
Crystalline gold clusters, irregular jagged edges, high density for size, and specific gravity consistent with precious metal content.
Color & Finish
Deep metallic yellow gold visible within a dark, gunmetal-grey to black host rock. Natural raw luster with mineralized patina.
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
Approximately 12mm x 15mm (Small specimen size)
Gemstones & Inlays
None; however, the host rock likely contains iron sulphides (pyrite/arsenopyrite) or dark quartz.
Clasp & Closure
Not applicable (Natural mineral specimen)
Chain & Links
Not applicable (Irregular geological structure)
Craftsmanship Details
N/A; purely nature-made geological formation.
Authentication Indicators
Sectility of the yellow metal (gold is soft and doesn't shatter like pyrite/fools gold), duller luster in shade vs. bright flash in sun, high density.
Origin & Maker
Natural occurrence; likely sourced from a hard-rock mine or alluvial deposit. No human maker.
Era & Period
Modern Geological Recovery (Holocene epoch formation)
Age Estimate
Formed millions of years ago; recently recovered from the earth.
Cultural Significance
Gold has been a primary driver of human migration and exploration (Gold Rushes) and serves as the universal standard of wealth across civilizations.
Condition Notes
Natural/Unprocessed. Surface presents raw geological textures without signs of tumbling or water-wear characteristic of river nuggets. Grade: High-grade specimen.
Value Estimate
Market value is based on 'Spot Price' x gold content, plus a specimen premium if the gold exposure is aesthetically pleasing (Estimated $150 - $400 USD).
Care & Maintenance
Keep dry to prevent oxidation of surrounding sulfide minerals; clean with softened water and a very soft brush if dusty; do not use chemicals.

Interesting Facts
Most gold is found as microscopic particles; finding 'free milling' gold large enough to see with the naked eye in its host rock makes it a specimen-grade find.
