Natural Crystalline Gold Specimen in Quartz Matrix
Raw Gold (nugget / specimen) · Natural Yellow Gold within a Quartz and Iron Oxide matrix. The color is a rich, saturated butter-yellow typical of high-purity lode gold.
Purity: High purity natural gold, typically ranging from 20K to 22K (83% to 92% fineness). Unlike refined gold, natural specimens contain trace amounts of silver and copper directly from the source.
Type
Raw Gold (nugget / specimen)
Purity
High purity natural gold, typically ranging from 20K to 22K (83% to 92% fineness). Unlike refined gold, natural specimens contain trace amounts of silver and copper directly from the source.
Gold Type
Natural Yellow Gold within a Quartz and Iron Oxide matrix. The color is a rich, saturated butter-yellow typical of high-purity lode gold.
Weight
Total specimen weight estimated at 1.5 to 3.0 grams. The actual gold content (specific gravity) appears to be approximately 0.5 to 1.2 grams of contained gold, with the remainder being host rock.
Description
A striking example of lode gold, this specimen features bright, metallic gold crystals emerging from a weathered quartz matrix. The contrast between the rich yellow gold and the iron-stained host rock makes it a desirable piece for both investors and mineral collectors. Unlike rounded river nuggets, this specimen retains its original sharp, crystalline structure, indicating it was recovered close to its primary source.
Key Features
Sharp crystalline gold formations; distinct iron oxide 'rust' staining indicating a gossan or vein origin; visible quartz attachment; high luster.
Color & Finish
Rich, deep yellow metallic luster for the gold portions; the matrix displays rusty orange (iron oxide staining) and translucent white (quartz). The gold features a natural crystalline finish with sub-hedral faces and a bright, sectile surface.
Hallmarks & Stamps
None. Natural geological specimens do not carry hallmarks or stamps as they are not manufactured items. Authenticity is determined via mineralogical characteristics.
Dimensions Estimate
Approximately 12mm x 15mm x 8mm. This is considered a 'thumbnail' sized specimen in mineral collecting.
Gemstones & Inlays
None. However, the gold is naturally embedded in crystalline Quartz (SiO2) which serves as the host mineral.
Clasp & Closure
Not applicable. This is a raw mineral specimen.
Chain & Links
Not applicable. The structure consists of interlocking metallic gold crystals and silicate minerals.
Craftsmanship Details
Natural hydrothermal crystallization. The gold was deposited molecule-by-molecule from superheated mineral-rich water cooling in crustal fractures.
Authentication Indicators
Characteristic uneven metallic luster (unlike the uniform glitter of pyrite); sectility (malleability) indicated by the way edges catch light; specific gravity appearing higher than the surrounding rock; lack of striations common in fool's gold.
Origin & Maker
Natural geological formation. Likely sourced from a lode deposit in regions such as California (Mother Lode), Alaska, or Australia (Victoria). Nature is the 'maker.'
Era & Period
Geological (Cenozoic to Precambrian depending on origin). These specimens are formed over millions of years through hydrothermal processes.
Age Estimate
Formed millions of years ago; recently extracted. The sharp edges of the gold suggest it was mined from a hard-rock vein rather than being water-worn in a river.
Cultural Significance
Raw gold specimens have sparked historical gold rushes (1849 California) and symbolize the 'raw' wealth of the earth. In many cultures, natural gold is believed to possess the pure energy of the sun.
Condition Notes
Natural/Unrefined. Grade: High-quality specimen. The gold is well-exposed and the matrix is stable. No signs of chemical cleaning or artificial enhancement are visible.
Value Estimate
$150 - $350 USD. The value carries a significant 'specimen premium' (30-50% above the spot gold price) because the gold is still attached to its host rock in an aesthetically pleasing way.
Care & Maintenance
Clean only with distilled water and a soft brush if dusty. Avoid harsh chemicals or ultrasonic cleaners which might shatter the quartz matrix. Store in a padded 'perky' box to prevent the soft gold from flattening.
Similar Items
Pyrite (Fool's Gold) which is more brittle and brassy; Chalcopyrite which has a greenish tint; or Placer Nuggets which are smooth and rounded from water erosion.
Interesting Facts
Gold is almost always found with quartz because both are deposited by the same hydrothermal fluids deep in the Earth's crust. Only about 2% of the world's gold is found in specimen form; most is crushed to dust during industrial mining.
