Natural Gold-Bearing Ore Sample
Raw Gold (Lode/Rock-hosted Ore) · Natural Native Yellow Gold in Host Rock (likely Quartz or Sulfide matrix)
Purity: Approximately 20K to 24K for the visible native gold inclusions; the total rock purity varies by grade (ppm/opt)
Type
Raw Gold (Lode/Rock-hosted Ore)
Purity
Approximately 20K to 24K for the visible native gold inclusions; the total rock purity varies by grade (ppm/opt)
Gold Type
Natural Native Yellow Gold in Host Rock (likely Quartz or Sulfide matrix)
Weight
Cannot be determined without physical volume; host rock density varies significantly
Description
A high-grade geological specimen of gold-bearing ore. The piece features visible native gold embedded within a crystalline mineral matrix. The host rock shows signs of mineralization with dark, potentially argentiferous or sulfide-rich sections contrasting sharply with the bright yellow luster of the gold.
Key Features
Visible 'free gold', irregular crystalline structure, geological matrix contact, natural metallic luster
Color & Finish
Vivid metallic yellow gold flecks against a dark gray, gunmetal, and brownish-black mineralized matrix
Hallmarks & Stamps
None (Raw geological specimen)
Dimensions Estimate
Specimen appears to be 3-6 cm in width based on macro photography grain size
Gemstones & Inlays
No gemstones; visible minerals potentially include pyrite, arsenopyrite, or chalcopyrite
Clasp & Closure
Not applicable (Raw mineral specimen)
Chain & Links
Not applicable
Craftsmanship Details
N/A - Natural geological formation; however, the 'cleanliness' of the presentation depends on the method of extraction/breaking
Authentication Indicators
Sectile (soft/malleable) appearance of yellow inclusions; lack of crystal faces typical of pyrite; metallic luster remains under different lighting angles
Origin & Maker
Natural occurrence; likely sourced from a hard-rock mining operation or lode deposit
Era & Period
Geological (Formation billions or millions of years ago)
Age Estimate
Geological age varying from Archean to Recent; modern recovery/extraction timestamp unknown
Cultural Significance
Represents the primary source of wealth and the starting point of the gold supply chain throughout human history
Condition Notes
Unprocessed/Rough state. Natural fractures and sharp edges consistent with broken-face ore samples
Value Estimate
Collector value for 'specimen gold' often exceeds the melt value of the gold content; value depends on aesthetic appeal and rarity
Care & Maintenance
Keep dry to prevent oxidation of associated sulfides. Handle with gloves to avoid skin oils affecting the matrix. Store in a padded specimen box.

Interesting Facts
Most gold is recovered from ore where it is invisible to the naked eye; samples with visible gold like this are rare and often kept as 'specimen gold'
