Raw Natural Gold Specimen in Quartz Matrix
Raw Gold (Nugget/Specimen) · Natural Yellow Gold with Host Rock (Matrix)
Purity: Estimated 18K to 22K (75-92% pure). Natural gold is rarely 24K and typically contains silver or copper alloys.
Type
Raw Gold (Nugget/Specimen)
Purity
Estimated 18K to 22K (75-92% pure). Natural gold is rarely 24K and typically contains silver or copper alloys.
Gold Type
Natural Yellow Gold with Host Rock (Matrix)
Weight
Estimated 2 to 5 grams total mass. Gold content varies significantly based on density compared to the matrix rock.
Description
A rugged, natural gold specimen featuring bright gold grains embedded within a dark, weathered quartz matrix. This piece showcases the organic way gold forms in hydrothermal veins, appearing as irregular 'flecks' or 'stringers' rather than a smooth nugget. The contrast between the metallic luster of the gold and the earthy, oxidized surface of the host rock makes it a compelling piece for mineral collectors or those interested in raw geology.
Key Features
Heterogeneous distribution of gold; jagged, unrefined edges; presence of orange-brown iron staining common in gold-bearing ore.
Color & Finish
Deep buttery yellow gold inclusions. The surface is raw, crystalline, and unpolished, with a dull grey and rust-colored quartz/limonite matrix.
Hallmarks & Stamps
None. As a raw geological specimen, it lacks man-made purity stamps or maker's marks.
Dimensions Estimate
Approximately 15mm x 10mm (Micro-specimen size). Small enough to be held between two fingertips.
Gemstones & Inlays
None. Natural mineral inclusions of quartz and iron oxides (limonite/hematite) are present.
Clasp & Closure
Not applicable; raw specimen.
Chain & Links
Not applicable; raw specimen. Note the striated, jagged texture of the host rock edge.
Craftsmanship Details
Naturally formed through hydrothermal deposition. No human craftsmanship; solely geological formation.
Authentication Indicators
Sectility (gold is malleable under a probe), high luster compared to 'fool's gold' (pyrite), and the specific mustard-yellow hue consistent with high purity natural alloys.
Origin & Maker
Produced by nature. Common origins for such specimens include California (USA), Australia, or Canada.
Era & Period
Contemporary Geological Sample (Holocene/Modern Discovery). Stylistically it represents a 'raw/organic' aesthetic.
Age Estimate
Geological age of millions of years; recently extracted/unearthed within the last 1-5 years.
Cultural Significance
Represents the 'Gold Rush' era aesthetic and the primary source of human wealth since antiquity.
Condition Notes
Raw/Natural condition. Features heavy surface abrasion and fracturing consistent with extraction from a larger rock body (crushed ore).
Value Estimate
Estimated $150 - $400 USD. Value is based on 'Specimen Value' (rarity and aesthetics) rather than just the weight of the gold (melt value).
Care & Maintenance
Do not use ultrasonic cleaners as they can shatter the quartz matrix. Clean with a soft brush and water only. Store in a padded gem jar.
Similar Items
Iron Pyrite (Fool's Gold), Chalcopyrite, or Gold-plated Quartz. Distinguished by gold's superior density and lack of crystal cleavage.
Interesting Facts
Most gold used in jewelry is melted down from ore like this. Only about 2% of the world's gold is found in nugget or specimen form, making these raw pieces rarer than processed bars.
