Raw Gold-Bearing Quartz Ore Specimen
Raw Gold (Geological Specimen/Ore Sample) · Natural Yellow Gold in Host Rock (Native Gold)
Purity: Unknown but likely high-fineness native gold (approx. 20K-24K or 83-99% gold) relative to the metallic inclusions; overall piece purity is very low as it is mostly rock matrix.
Type
Raw Gold (Geological Specimen/Ore Sample)
Purity
Unknown but likely high-fineness native gold (approx. 20K-24K or 83-99% gold) relative to the metallic inclusions; overall piece purity is very low as it is mostly rock matrix.
Gold Type
Natural Yellow Gold in Host Rock (Native Gold)
Weight
15 to 30 grams (Estimated for a specimen of this size and visible density)
Description
A raw, unrefined gold-bearing ore specimen featuring visible wire-like or crystalline gold disseminated through a matrix of quartz and darker sulfide minerals. The specimen shows the 'in-situ' relationship between the metal and its host rock, characteristic of lode gold mining. It has a jagged, fractured surface showing the interior mineralization.
Key Features
Visible 'Free Gold' on the surface, presence of quartz and probable iron sulfides (pyrite/arsenopyrite), unique geological fracture pattern.
Color & Finish
Naturally vibrant buttery yellow to brassy gold veins; finish is raw, jagged, and unrefined with a dull grey and white quartz matrix.
Hallmarks & Stamps
None. Natural geological specimens do not carry hallmarks or purity stamps.
Dimensions Estimate
35mm x 25mm x 10mm (Handheld specimen size)
Gemstones & Inlays
None. The gold is naturally occurring within a milky quartz and sulfide-rich host rock.
Clasp & Closure
Not applicable; natural rock specimen.
Chain & Links
Not applicable; raw mineral form.
Craftsmanship Details
Natural 'craftsmanship' by tectonic and hydrothermal activity. No human modification aside from extraction/breaking the stone.
Authentication Indicators
Color depth (gold vs. pyrite), irregular morphology (gold is malleable, pyrite is brittle/cubic), and lack of 'green' oxidation common in brass fakes. Requires XRF or specific gravity test for precise metal content.
Origin & Maker
Origin unknown (likely from a lode deposit mine); created by geological hydrothermal processes.
Era & Period
Contemporary/Geological (Natural formation likely millions of years old; recently extracted)
Age Estimate
Millions of years (Geological age); extracted within the last decade.
Cultural Significance
Represents the primary source of wealth throughout human history; pieces like this drove the famous Gold Rushes of the 19th century.
Condition Notes
Raw/Unprocessed. The specimen is in its natural state post-extraction. High risk of 'brittle' gold flakes shedding if not handled carefully.
Value Estimate
Primarily collector/specimen value (typically $50 - $150 depending on total gold weight and aesthetic appeal). Melt value is difficult to determine without destroying the specimen.
Care & Maintenance
Do not clean with harsh chemicals. Use only mild distilled water. Store in a padded gem jar or display box to prevent loss of gold flakes through friction.
Similar Items
Iron Pyrite ('Fool's Gold'), Chalcopyrite, or gold-plated rock. Real gold remains bright in shadow, whereas pyrite requires direct light to shine.
Interesting Facts
Most gold found in quartz vein deposits was deposited by super-heated water miles underground, which then cooled and crystallized over hundreds of thousands of years.
