Raw Gold (Specimen in Quartz/Host Rock Matrix) · Yellow Gold (Natural Native Alloy)
Purity: Geological Native Gold (Typically 18K to 23K / 75% to 98%)
Type
Raw Gold (Specimen in Quartz/Host Rock Matrix)
Purity
Geological Native Gold (Typically 18K to 23K / 75% to 98%)
Gold Type
Yellow Gold (Natural Native Alloy)
Weight
Indeterminate (Gold content hidden within matrix; total specimen weight potentially several kilograms)
Description
A raw, unrefined mineral specimen featuring flecks and small veins of native gold embedded within a complex host rock matrix. The image displays a rugged, dark, and iron-rich stone with visible crystalline textures and metallic inclusions characteristic of lode gold deposits. These pieces are highly sought after by mineral collectors who value the 'as-found' presentation of the metal before it is processed or smelted into bullion.
Key Features
Randomized crystalline structure, irregular metallic distribution, and absence of human-made tool marks
Color & Finish
Deep brassy yellow inclusions against dark basaltic/siliceous matrix with heavy iron-staining (patina)
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
Macro view suggests a specimen approximately 10-20cm in width
Gemstones & Inlays
Natural mineral inclusions; likely quartz, pyrite, and iron oxides
Clasp & Closure
None (Natural raw state)
Chain & Links
N/A (Crystalline matrix structure)
Craftsmanship Details
Natural mineralization; interlocking crystal boundaries and hydrothermal deposition patterns.
Authentication Indicators
Irregular crystalline shapes, characteristic yellow luster under light, and lack of 'brassy' flaking typical of pyrite (Fools Gold)
Origin & Maker
Natural geological formation; Mother Nature
Era & Period
Geological (Pre-human; likely Cenozoic or Mesozoic formation)
Age Estimate
Millions of years old
Cultural Significance
Represents the 'Gold Rush' heritage and the primary form of wealth extraction throughout human history.
Condition Notes
Unrefined/Raw. Surface shows oxidation (rusting) from environmental exposure and mechanical impact from extraction.
Value Estimate
Specimen value: $500 - $2,500 depending on actual gold volume; Melt value depends on destructive assay processing.
Care & Maintenance
Keep dry to prevent further iron oxidation; do not use chemicals. Clean only with distilled water and a soft brush.
Similar Items
Chalcopyrite or Pyrite (Fools Gold) - distinguished by brittle texture and greenish-black streak; Gold-bearing quartz - typically white rather than dark matrix.
Interesting Facts
Most of the world's gold was delivered to Earth's surface via asteroid impacts billions of years ago; less than 1% of the gold ever mined is still in this specimen form.
