Natural Gold-Bearing High-Grade Quartz Specimen
Raw Gold (nugget, flake, and lode gold in matrix) · Native Yellow Gold. This is a natural geological formation as opposed to a refined alloy.
Purity: Approximately 20K-23K (83% - 96% native purity). Native gold in quartz usually exists as a high-purity alloy of gold and silver (electrum).

Purity
Approximately 20K-23K (83% - 96% native purity). Native gold in quartz usually exists as a high-purity alloy of gold and silver (electrum).
Gold Type
Native Yellow Gold. This is a natural geological formation as opposed to a refined alloy.
Weight
Indeterminate from image. Typical specimens of this appearance range from 50g to 500g, with gold content representing a fraction of the total weight.
Description
A striking example of lode gold or 'gold in quartz.' This specimen features visible threads and crystalline clusters of metallic gold embedded within a host rock of milky white quartz. The presence of dark, oxidized iron indicates a typical hydrothermal vein environment. Unlike smooth river-worn nuggets, this gold retains its sharp, dendritic, and jagged character, indicating it has not been moved far from its primary source.
Key Features
Crystalline gold clusters, contrasting white quartz matrix, iron oxide 'rust' staining typical of high-grade ore, and a lack of mechanical wear or rounding.
Color & Finish
Rich buttery yellow metallic inclusions within a white milky quartz and reddish-brown limonite/iron oxide matrix. Natural crystalline and jagged surface texture.
Hallmarks & Stamps
None. Natural geological specimens do not carry hallmarks as they are unrefined and not minted or manufactured.
Dimensions Estimate
Macro view suggests a specimen approximately 2 to 4 inches in length; specific dimensions are impossible to verify without scale.
Gemstones & Inlays
Natural Quartz (matrix). Visible iron oxide staining (limonite) providing a secondary reddish-brown decorative element.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; raw mineral specimen.
Craftsmanship Details
Naturally formed through hydrothermal deposition. No human craftsmanship involved; the value lies in the natural rarity and the quality of the extraction process to keep the specimen intact.
Authentication Indicators
Metallic luster consistent with native gold, hackly fracture, and distinct association with quartz. Lack of cubic crystal structure (which would indicate pyrite/Fools Gold) or mica-like cleavage (which would indicate weathered biotite/mica).
Origin & Maker
Natural geological origin. Likely from a hard-rock mining district such as the California Mother Lode, Alaska, or Western Australia.
Era & Period
Geological/Cenozoic to Precambrian depending on locality. Collected in the contemporary era (late 20th - early 21st century).
Age Estimate
The gold was deposited millions of years ago; the specimen appears to have been recently extracted or unearthed within the last few decades.
Cultural Significance
Specimens like this fueled the 19th-century Gold Rushes (California, Klondike, Victoria). Today, they are prized by mineral collectors and often used in high-end 'Gold Quartz' jewelry, particularly in Alaska and Australia.
Condition Notes
Fair to Good. The specimen appears raw and uncleaned; significant host rock remains. Gold is visible but somewhat obscured by iron staining and dirt. Structural integrity of the quartz appears fractured.
Value Estimate
Primarily determined by 'specimen value' which exceeds melt value. If cleaned, such pieces can sell for 1.5x to 3x the contained gold spot price depending on the visual aesthetics of the gold distribution.
Care & Maintenance
Do not use harsh chemicals or mechanical polishers. Clean with mild soapy water. Use a soft ultrasonic cleaner only if the quartz is stable. Avoid dropping, as quartz is brittle and gold is soft.
Similar Items
Gold-bearing Pyrite (lighter and brittle), Chalcopyrite (softer and iridescent), or placer gold nuggets (rounded and water-worn).
Interesting Facts
Quartz and gold are often found together because they both precipitate from hot, mineral-rich water moving through cracks in the Earth's crust. It takes roughly 20 to 100 tons of rock to produce one ounce of gold in many commercial mines, making visible 'jewelry-grade' gold-in-quartz quite rare.
