Gold-Bearing Quartz Ore Specimen
Raw Gold / Mineral Specimen · Natural Native Gold in crystalline Quartz host rock.
Purity: Natural gold in quartz typically ranges between 18K and 22K (80-92% purity); however, this is an unrefined specimen with significant non-gold matrix.

Purity
Natural gold in quartz typically ranges between 18K and 22K (80-92% purity); however, this is an unrefined specimen with significant non-gold matrix.
Gold Type
Natural Native Gold in crystalline Quartz host rock.
Weight
Estimated total specimen weight 40-60 grams; visible gold content appears to be less than 0.5 gram based on surface exposure.
Description
A classic lode gold specimen featuring a dense white quartz matrix. Small, disseminated specks of native gold are visible within the crystalline structure. This is not a nugget, but rather 'gold-in-quartz' ore, representing the primary source from which placer gold is eroded.
Key Features
White crystalline quartz host; metallic yellow inclusions; irregular jagged morphology; lack of alluvial smoothing.
Color & Finish
White to grayish crystalline quartz matrix with minute flecks of metallic yellow gold. Raw, un-weathered mineral surface.
Hallmarks & Stamps
None; unrefined natural geological specimens do not carry hallmarks or purity stamps.
Dimensions Estimate
Approximately 35mm x 30mm x 25mm based on hand proportion.
Gemstones & Inlays
None. The item is a combination of host quartz and native metallic gold particles.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable. The texture is rough, crystalline, and irregular (lode gold formation).
Craftsmanship Details
Natural geological formation; no human craftsmanship involved other than extraction/cleaning.
Authentication Indicators
Sectility (gold is soft and can be poked with a pin unlike pyrite) and high luster. Red flag: The image lacks high-contrast metallic luster, which might suggest iron pyrite (Fool's Gold) or mica rather than precious gold.
Origin & Maker
Natural Geological Origin; common in regions like the Mother Lode (California), Australian Goldfields, or Canadian Shield.
Era & Period
Geological / Pre-human formation. Likely harvested via modern prospecting or mining.
Age Estimate
Geological age likely millions of years; recovery date unknown but surface suggests recent extraction.
Cultural Significance
Represents the 'Gold Rush' era of hard-rock mining; symbolic of industrial prospecting and the geological wealth of the earth.
Condition Notes
Raw mineral state. Quartz shows some fracturing; gold is localized. Grade: Mineral Specimen.
Value Estimate
Primarily specimen value. As ore, it is worth more to a collector ($20-$50) than as melt, as the gold extraction cost would exceed the value of the minute gold present.
Care & Maintenance
Keep away from harsh acids (though quartz is resistant); store in a padded display case to prevent the brittle quartz from chipping.
Similar Items
Gold nuggets (smooth, water-worn), Iron Pyrite (brittle, brassy cubes), Chalcopyrite (softer, more colorful tarnish).
Interesting Facts
Most of the world's gold is found in quartz veins; large nuggets are actually rarer than these small disseminated particles.
