Natural Gold-Bearing Quartz Ore Specimen
Raw Gold (nugget/ore specimen) · Native Yellow Gold within a host matrix.
Purity: High-purity native gold, typically ranging from 20K to 23K (83% - 96%). In its raw form, it is unrefined and contains naturally occurring silver or copper alloys.
Type
Raw Gold (nugget/ore specimen)
Purity
High-purity native gold, typically ranging from 20K to 23K (83% - 96%). In its raw form, it is unrefined and contains naturally occurring silver or copper alloys.
Gold Type
Native Yellow Gold within a host matrix.
Weight
Estimated 0.5 to 2.0 grams total specimen weight. The visible gold content likely accounts for less than 0.1 grams of the total mass.
Description
A raw, unrefined gold ore specimen featuring visible wire or flake gold embedded within a quartz matrix. The gold exhibits the classic deep yellow saturation characteristic of high-purity native metal. This is a classic 'lode gold' sample, representing how gold is found in situ before it is eroded into placer deposits or processed by mills.
Key Features
Metallic gold luster that remains bright in shadow (unlike pyrite), jagged quartz edges, and lack of planar cleavage in the gold flakes.
Color & Finish
Rich buttery yellow with high metallic luster. The host rock is a mix of milky to translucence white quartz and greyish host rock with a rough, crystalline fracture.
Hallmarks & Stamps
None. As a natural geological specimen, it lacks man-made stamps. Authenticity is determined by crystalline structure and density.
Dimensions Estimate
Approximately 12mm x 15mm (Small thumbnail-sized specimen).
Gemstones & Inlays
No gemstones, but features milky quartz and possible minor sulfides (pyrite or arsenopyrite) within the host matrix.
Clasp & Closure
Not applicable/No closure.
Chain & Links
Not applicable; features a jagged, natural crystalline fracture surface.
Craftsmanship Details
Natural geological formation; no human craftsmanship present. The specimen shows natural fracture lines consistent with being hammered or broken from a larger vein.
Authentication Indicators
The 'sectoral' appearance of the gold, its malleability (if tested), and the fact that the color does not change when viewed from different angles. Pyrite (fool's gold) would appear more brassy and show cubic crystal structures.
Origin & Maker
Produced by nature; potentially from a lode deposit in regions like California (USA), Australia, or Canada where ‘gold-in-quartz’ is common.
Era & Period
Contemporary Geological Find (formed millions of years ago, recently extracted).
Age Estimate
Geologically millions of years old; recently recovered from a mining or prospecting site.
Cultural Significance
Represents the 'Gold Rush' heritage and the primary source of wealth for many civilizations throughout history.
Condition Notes
All-natural condition. Structure is stable but brittle due to the quartz matrix. Grade: Cabinet-grade specimen (Good).
Value Estimate
Primarily specimen value. As gold content is minimal, value sits between $20 and $50 USD for its aesthetic and geological interest rather than its melt value.
Care & Maintenance
Keep in a display case; do not clean with harsh chemicals. Avoid ultrasonic cleaners as they can shatter the quartz matrix. Dust with a soft brush only.
Similar Items
Iron Pyrite (Fool's Gold), Chalcopyrite, or Gold-Vermeil rock (man-made). Pyrite is harder and more brittle, while chalcopyrite often has an iridescent 'peacock' tarnish.
Interesting Facts
Most gold is found in quartz veins because hot, mineral-rich fluids circulate through crustal cracks, depositing quartz and gold together as they cool.
