Raw Gold-Bearing Quartz Ore Specimen
Raw Gold Ore / Mineral Specimen · Native Yellow Gold within a Quartz matrix.
Purity: Estimated trace to moderate based on bulk. Naturally occurring gold in quartz is typically 22K-24K purity (92-99% gold), but the total specimen purity is dependent on the host rock-to-metal ratio.

Purity
Estimated trace to moderate based on bulk. Naturally occurring gold in quartz is typically 22K-24K purity (92-99% gold), but the total specimen purity is dependent on the host rock-to-metal ratio.
Gold Type
Native Yellow Gold within a Quartz matrix.
Weight
7.96 lbs (Gross weight of the specimen as shown on the scale).
Description
A large, heavy specimen of gold-bearing quartz ore. The host rock appears to be a mix of milky and smoky quartz with heavy mineralization and iron-rich staining. Such specimens are characteristic of lode deposits where hydrothermal fluids deposited gold within quartz veins.
Key Features
Large bulk weight, jagged crystalline structure, and trace metallic inclusions. High density compared to non-mineralized quartz.
Color & Finish
Dull off-white to grey quartz matrix with possible brownish iron staining. Potential gold visible as metallic yellow specks or veins with a characteristic buttery yellow luster.
Hallmarks & Stamps
None (Natural geological specimen).
Dimensions Estimate
Approximately 8 to 10 inches in length and 6 inches in height based on scale footprint.
Gemstones & Inlays
Milky quartz matrix; possible associated sulfide minerals like pyrite or arsenopyrite.
Clasp & Closure
Not applicable (Natural rock).
Chain & Links
Not applicable (Natural rock).
Craftsmanship Details
Natural geological formation created via hydrothermal deposition; no human craftsmanship involved.
Authentication Indicators
Weight/density of the specimen (7.96 lbs) is consistent with highly mineralized rock. True gold will maintain its yellow hue in shade, whereas pyrite (fools gold) will lose its shimmer. Requires a crush test or XRF scan for exact content.
Origin & Maker
Natural geological formation; commonly found in hard rock mining districts in Western USA, Australia, or Canada.
Era & Period
Geological formation; millions of years old.
Age Estimate
Pre-Cambrian to Cenozoic depending on the specific mining district.
Cultural Significance
Represents the 'Gold Rush' eras of the 19th century and the foundation of hard-rock mining industries.
Condition Notes
Raw, unrefined mineral state. Grade: Natural Ore Specimen. Structure is solid but prone to micro-fractures common in quartz.
Value Estimate
Primarily industrial/specimen value until assayed. If visible gold is high, value could exceed spot gold price as a collector's mineral. Otherwise, value is based on the extractable gold content minus refining costs.
Care & Maintenance
Keep dry and avoid acidic cleaners which may react with associated sulfide minerals. Brush with a soft dry cloth.

Interesting Facts
Most of the world's gold was originally found in quartz veins like this. Miners used to call high-grade ore like this 'jewelry grade' if the gold was visible to the naked eye.
