Gold-Bearing Quartz Ore Specimen (Raw Gold)
Raw Gold / Gold Ore · Native Yellow Gold (unrefined) embedded in host rock (Quartz/Iron-stained matrix).
Purity: Variable; typically 75% to 95% (18K to 23K) within the native gold inclusions, though the overall rock mass has a much lower total gold yield per ton.
Type
Raw Gold / Gold Ore
Purity
Variable; typically 75% to 95% (18K to 23K) within the native gold inclusions, though the overall rock mass has a much lower total gold yield per ton.
Gold Type
Native Yellow Gold (unrefined) embedded in host rock (Quartz/Iron-stained matrix).
Weight
15 to 25 grams for the total specimen; gold content is likely measured in grains or milligrams unless the interior is highly concentrated.
Description
A rugged and authentic piece of gold-bearing ore. This specimen features visible native gold flecks peppered throughout a dark, iron-stained quartz matrix. Unlike refined bullion, this piece showcases gold in its original geological context, offering a raw and visceral connection to the earth's mineral wealth. Its jagged edges and varied mineral composition make it a unique collector's piece or a physical reminder of the 'Gold Rush' era.
Key Features
Visible native gold luster, heavy density relative to size, iron-oxide staining (indicating gold-friendly mineralization), and lack of geometric crystal habit common in pyrite.
Color & Finish
Naturally weathered earth tones (ochre, brown, and grey) with brilliant, metallic yellow flakes or micro-nuggets; rough, crystalline, and unpolished surface.
Hallmarks & Stamps
None; natural raw specimens lack hallmarks. Identification depends on geological characteristics.
Dimensions Estimate
Approximately 2.5 cm x 1.5 cm x 1.2 cm; fits within the fingertip area of a standard adult hand.
Gemstones & Inlays
None; however, the gold is naturally 'inlaid' into a matrix of crystalline quartz and possibly pyrite or iron oxides.
Clasp & Closure
None; raw mineral specimen.
Chain & Links
Not applicable; the structure consists of natural geological bonding between the gold and the silicate matrix.
Craftsmanship Details
Forged by nature through hydrothermal deposition; the gold was deposited by superheated, mineral-rich water in quartz veins deep within the crust.
Authentication Indicators
Visual luster remains constant in shade/sunlight; jagged, malleable appearance of metal flecks; high density; 'Fool's Gold' (pyrite) would appear more brassy and cubic.
Origin & Maker
Natural origin; likely a placer or lode find from a gold-bearing region like California (Sierras), Australia, or Alaska. 'Made' by geological pressure.
Era & Period
Modern Discovery; the gold itself formed over millions of years through hydrothermal processes.
Age Estimate
Geological age: 50 million to 200 million years; Discovery date: Contemporary.
Cultural Significance
Represents the primary source of human wealth and the driving force behind the global migration movements of the 19th century.
Condition Notes
Natural Raw Condition; displays typical field-find characteristics including dirt residue and minor surface abrasion. No signs of chemical leaching.
Value Estimate
Primarily valued as a mineral specimen. Market value: $40 to $100 depending on total gold weight and aesthetic appeal. Melt value is negligible.
Care & Maintenance
Keep dry; clean only with water and a soft brush; avoid acids which may dissolve the host rock or oxidize the minerals; store in a padded gem jar.

Interesting Facts
Most gold is found in tiny particles invisible to the naked eye; a 'specimen' piece like this with visible gold is actually rarer than refined gold bars.
