Raw Gold Ore Specimen with Quartz Veining
Raw Gold (nugget/specimen) · Natural Yellow Gold in Host Rock (typically quartz or iron-rich matrix).
Purity: Likely 20K to 22K (83% - 92% purity) for the visible gold inclusions, typical of natural placer or lode gold.
Type
Raw Gold (nugget/specimen)
Purity
Likely 20K to 22K (83% - 92% purity) for the visible gold inclusions, typical of natural placer or lode gold.
Gold Type
Natural Yellow Gold in Host Rock (typically quartz or iron-rich matrix).
Weight
Estimated 5 to 10 grams total mass including host rock; actual gold content likely 1-2 grams.
Description
A raw mineral specimen consisting of native gold disseminated through a host matrix. The piece shows characteristic jagged, metallic gold flakes embedded in quartz, showing the 'lode' style of gold formation before it is weathered into river nuggets.
Key Features
Natural crystalline gold leafing, presence of white quartz veining, and uneven metallic luster that does not tarnish.
Color & Finish
Brassy, semi-lustrous yellow inclusions set against a matte gray and off-white mineral matrix.
Hallmarks & Stamps
None. Natural raw gold does not feature man-made hallmarks.
Dimensions Estimate
Approximately 25mm x 15mm; specimen size fits within a thumb/finger grip.
Gemstones & Inlays
Natural crystalline quartz and iron oxides; no faceted gemstones.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; rugged, uneven natural fracture surface.
Craftsmanship Details
None; natural geological formation shaped by hydrothermal pressure and mineral crystallization.
Authentication Indicators
Sectile nature (gold is soft and doesn't shatter), high density relative to size, and streak test results (gold leaves a golden yellow streak). Red flag check: Pyrite (Fool's Gold) would be more brittle and cubic in structure.
Origin & Maker
Geological origin; appearance is consistent with lode gold from regions like California (USA), Australia, or West Africa.
Era & Period
Geological contemporary; likely recently extracted or prospected.
Age Estimate
Geologically millions of years old; recently mined within the last 10 years.
Cultural Significance
Represents the primary state of the 'Gold Rush' era across the globe, symbolizing raw wealth and geological fortune.
Condition Notes
Natural raw state; fragile matrix. The gold is partially exposed and hasn't been chemically cleaned or 'roasted'. Grade: Natural Specimen.
Value Estimate
Primarily valued as a mineral specimen. If 1-2g of gold is present, 'melt' value is ~$65-$130, but collector value may reach $150-$200 based on aesthetics.
Care & Maintenance
Keep dry; do not clean with acids or ultrasonic cleaners which could dissolve the host rock or dislodge the gold flakes.

Interesting Facts
Most gold is found in tiny particles invisible to the naked eye; a specimen where the gold is clearly visible like this is rare and sought after by mineral collectors.
