Natural Gold-Bearing High-Grade Quartz Ore
Raw Gold (ore/specimen) · Native Yellow Gold within a white/grey quartz and sulfide mineral matrix.
Purity: 24K Fine Gold particles embedded in host matrix; purity of individual gold flakes is typically 85-97% (approx. 20K-23K) in nature.
Type
Raw Gold (ore/specimen)
Purity
24K Fine Gold particles embedded in host matrix; purity of individual gold flakes is typically 85-97% (approx. 20K-23K) in nature.
Gold Type
Native Yellow Gold within a white/grey quartz and sulfide mineral matrix.
Weight
Indeterminate from image; specimen appears to be hand-held, likely 20-100 grams total specimen weight with milligrams of visible gold.
Description
A high-grade gold-in-quartz specimen featuring visible 'free-milling' gold scattered across a fractured mineral surface. This represents gold in its primary source state before being eroded into placer deposits or refined into bullion. The gold presents as irregular, jagged grains and thin leaf-like structures nestled between quartz crystals, displaying the classic hackly fracture and metallic sheen characteristic of high-purity native gold.
Key Features
Visible 'leaf gold' habit, lack of crystalline symmetry (unlike pyrite), and high-contrast color against the dark host matrix.
Color & Finish
Deep buttery yellow gold against a dull, matte grey-white crystalline host rock. The gold exhibits a natural, rough, unpolished metallic luster.
Hallmarks & Stamps
None; natural geological formation. No man-made markings present.
Dimensions Estimate
Specimen appears to be approximately 3cm x 4cm based on finger scale.
Gemstones & Inlays
None; however, the gold is naturally 'inlaid' into quartz (silica) and possibly associated with pyrite or arsenopyrite crystals.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; raw mineral specimen.
Craftsmanship Details
Nature-formed; showing natural hydrothermal deposition patterns where gold was carried by hot fluids into quartz veins.
Authentication Indicators
Sectile nature (gold would dent/cut rather than shatter like pyrite), deep yellow color (pyrite is brassy/pale), and lack of tarnish (unlike mica).
Origin & Maker
Natural geological origin; commonly found in orogenic gold deposits (e.g., California, Australia, or Yukon).
Era & Period
Geological/Prehistoric formation; contemporary 'as-found' status.
Age Estimate
Geological age likely millions of years; recently extracted or discovered.
Cultural Significance
Represents the 'Gold Rush' archetype; symbolizing the raw material that fueled global migrations and economic development in the 19th century.
Condition Notes
Raw/Natural condition. The specimen shows fresh fracture surfaces, likely from manual crushing or prospecting extraction. No chemical cleaning or 'shining' appears present.
Value Estimate
Valued primarily as a collector's specimen rather than by melt weight. Specimen value likely ranges from $50 - $250+ depending on the total 'show' of gold.
Care & Maintenance
Keep in a display case; handle with care as gold is soft and can be rubbed off or scratched. Do not use harsh chemicals which may dissolve the host matrix.
Similar Items
Iron Pyrite (Fool's Gold), Chalcopyrite, or Gold-plated rock. Real gold remains yellow even in shadow, whereas pyrite requires direct light to shine.
Interesting Facts
The 'Gold-in-Quartz' look is highly sought after for high-end lapidary work where the rock is sliced and polished into 'natural gold' jewelry cabochons.
