Natural Gold-in-Quartz Raw Mineral Specimen
Raw Gold (nugget/flake in host matrix) · Natural Yellow Gold in crystalline quartz matrix
Purity: Estimated 20K to 24K (83%-99.9%)
Type
Raw Gold (nugget/flake in host matrix)
Purity
Estimated 20K to 24K (83%-99.9%)
Gold Type
Natural Yellow Gold in crystalline quartz matrix
Weight
Total specimen estimate 2.0 to 3.5 grams; gold content likely <0.2 grams
Description
A raw, unrefined specimen of 'Gold Quartz' consisting of a milky-to-translucent quartz host rock containing thin veins or 'stringers' of native gold. This item represents gold in its primary geological state, where mineral-rich hot water once deposited gold within fractured quartz veins deep underground.
Key Features
Intergrowth of native gold within silicate minerals; irregular, jagged surface typical of untreated lode gold.
Color & Finish
Vivid buttery yellow gold with a dull/milky white quartz finish and dark iron/sulfide inclusions
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
Approximately 15mm x 10mm x 8mm
Gemstones & Inlays
Crystalline Milky Quartz (SiO2) acts as the host matrix
Clasp & Closure
None (Naturally occurring mineral)
Chain & Links
N/A (Jagged crystalline structure with irregular fractures)
Craftsmanship Details
Natural geological formation; no human craftsmanship or refinement visible.
Authentication Indicators
Sectility (gold can be poked with a needle without shattering, unlike pyrite); distinctive rich color depth; lack of cleavage in the yellow material.
Origin & Maker
Naturally occurring; common to hydrothermal vein deposits (e.g., California, Alaska, or Australia)
Era & Period
Geological formation (Millions of years old)
Age Estimate
Formation age: Paleozoic to Cenozoic era; recently mined/found
Cultural Significance
Gold-in-Quartz has been used in jewelry since the California Gold Rush (1849) as a symbol of the rugged frontier and mineral wealth.
Condition Notes
Natural/Rough condition; features sharp edges and some iron-oxide staining (brown/grey areas) on the host rock surface.
Value Estimate
Primarily specimen value ($20-$50) rather than melt value, as the gold content is physically minimal but aesthetically pleasing.
Care & Maintenance
Avoid harsh acids that might dissolve the matrix; clean with a soft brush and distilled water; store in a padded specimen box to prevent quartz chipping.

Interesting Facts
Most gold found by hobbyists is 'placer' gold (smooth nuggets), but this is 'lode' gold, found directly in the rock where it formed.
