Raw High-Grade Gold Quartz Ore Specimen
Raw Gold (ore specimen) · Natural Yellow Gold native to a host rock matrix, likely containing trace silver (electrum) or iron.
Purity: Natural gold in quartz typically ranges from 20K to 23K (83% to 96% purity). This is a geological specimen, not a refined alloy.

Purity
Natural gold in quartz typically ranges from 20K to 23K (83% to 96% purity). This is a geological specimen, not a refined alloy.
Gold Type
Natural Yellow Gold native to a host rock matrix, likely containing trace silver (electrum) or iron.
Weight
Based on hand-scale, specimen appears to be approximately 300 to 500 grams total weight. The actual gold content (melt weight) is likely a small percentage of total mass.
Description
A rugged and visually striking raw gold ore specimen. Tiny clusters of native gold are visible throughout a host matrix of fractured quartz and dark host rock. This piece represents gold in its primary geological state before refining, showing the intricate way precious metal precipitates in rock veins. It possesses a raw, earthy aesthetic highly valued by mineral collectors.
Key Features
Metallic luster of gold flecks, non-reactive surface, association with quartz (the primary host for lode gold), and high density relative to standard rocks.
Color & Finish
Naturally occurring buttery yellow metallic flecks against a backdrop of greyish-white quartz and dark mineral inclusions. Surface is raw, jagged, and unpolished.
Hallmarks & Stamps
None. As a raw geological specimen, there are no stamps. Authenticity is determined by mineral structure and specific gravity.
Dimensions Estimate
Estimated 10 cm x 7 cm x 4 cm; fits comfortably in the palm of a hand.
Gemstones & Inlays
None. The gold is naturally embedded within a crystalline quartz and sulfide mineral matrix.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; rugged, fractured rock texture with crystalline structure.
Craftsmanship Details
Nature-formed. Characteristics include crystalline growth patterns of the gold and the hydrothermal crystallization of the surrounding quartz.
Authentication Indicators
Sectility (gold is soft and can be poked, unlike brittle pyrite), metallic streak, and the heavy 'heft' of the specimen. Red flag check: Pyrite (Fool's Gold) is brittle and would crush to powder.
Origin & Maker
Natural origin. Likely from a lode deposit in regions like the Sierra Nevada (USA), Western Australia, or the Canadian Shield.
Era & Period
Contemporary Geologic (Modern Discovery); The specimen itself was formed millions of years ago during hydrothermal mineralization.
Age Estimate
Geological age is millions of years; recovery date is likely within the last 5-10 years.
Cultural Significance
Represents the fundamental human drive for prospecting and mining that fueled historical Gold Rushes and built entire nations.
Condition Notes
Raw/Natural. The specimen shows natural fracture planes and typical oxidation of secondary minerals (iron/pyrite). Structural integrity is solid rock.
Value Estimate
Primary value is as a mineral specimen. If gold content is high, it carries a premium over spot price for its 'decorative' value to collectors, often 1.5x to 3x the melt value.
Care & Maintenance
Keep dry to prevent oxidation of host minerals; clean only with distilled water and a soft brush; store in a padded display case.
Similar Items
Pyrite (Fool's Gold), Chalcopyrite, or Arsenopyrite specimens. These lack the softness and deep yellow hue of true native gold.
Interesting Facts
The 'Gold-Quartz' relationship occurs when hot, mineral-rich fluids are forced into rock fissures deep underground. Most gold jewelry begins in this raw state.
