Type
Raw Gold Ore (Matrix Specimen)
Purity
Approximately 75% - 95% (18K to 23K equivalent) for the native gold inclusions
Gold Type
Natural Native Yellow Gold
Weight
Variable; gold content represents a small fraction of total specimen weight
Description
An authentic specimen of native gold embedded within its host quartz matrix. This piece displays 'free-milling' gold, where the precious metal is visible to the naked eye as wires or irregular grains. The surrounding rock shows oxidized staining, typical of gold-bearing hydrothermal veins.
Key Features
Crystalline structure of gold grains, distinct metallic yellow color against dull host rock, irregular leaf-like growth
Color & Finish
Rich buttery yellow with a natural metallic luster; unrefined and jagged
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
Macro view; estimated specimen size 3cm to 8cm
Gemstones & Inlays
None; host rock consists of crystalline quartz and iron-stained silicates
Clasp & Closure
Not applicable
Chain & Links
Not applicable; rough rock fracture edges
Craftsmanship Details
Natural mineralization; no human intervention other than extraction and cleaning.
Authentication Indicators
Sectile (malleable) nature of gold vs. brittle fool's gold; color remains constant under different lighting angles
Origin & Maker
Natural geological formation; possibly Western USA, Australia, or Canada
Era & Period
Modern Geological Discovery (Cenozoic or older formation)
Age Estimate
Geologically millions of years old; recently extracted
Cultural Significance
Represents the 'Gold Rush' heritage and the primary source of human wealth for millennia.
Condition Notes
Natural raw state; includes surface dust and iron oxide (rust) staining
Value Estimate
Specimen value exceeds melt value; priced based on 'visible gold' aesthetic for collectors.
Care & Maintenance
Keep dry; clean with distilled water and a soft brush; avoid acids that may react with host minerals.
Similar Items
Iron Pyrite (Fool's Gold), Chalcopyrite, or Mica; distinguished by the lack of brittleness and rich yellow-orange hue.
Interesting Facts
Most of the world's gold was originally formed in hydrothermal veins like this one, deposited by superheated water deep in the Earth's crust.
