Type
Raw Gold (Nugget/Specimen in Matrix)
Purity
Indeterminate; Natural gold nuggets usually range from 20K to 23K (83% to 97% fineness).
Gold Type
Natural Yellow Gold native alloy (typically contains trace silver and copper).
Weight
25 to 45 grams total (combined weight of quartz matrix and gold inclusions).
Description
A raw geological specimen featuring metallic gold veins embedded within a translucent quartz matrix. The piece shows a rugged, unpolished surface typical of lode gold, where the gold is still bonded to its primary host mineral. The quartz displays a slight vitreous luster with internal fractures, while the gold provides high-contrast metallic flashes.
Key Features
In-situ gold mineralization, crystalline quartz structure, iron-rich dirt adhering to crevices, and irregular natural shape.
Color & Finish
Pale to buttery yellow metallic inclusions within a translucent milky white to peach-toned quartz.
Hallmarks & Stamps
None; Natural specimens do not feature man-made stamps or hallmarks.
Dimensions Estimate
Approximately 40mm x 35mm x 15mm.
Gemstones & Inlays
Host rock consists of crystalline Quartz (SiO2) with possible iron oxide staining (limonite).
Clasp & Closure
Not applicable; Raw geological specimen.
Chain & Links
Not applicable; Features irregular, jagged geological fracturing and quartz crystal faces.
Craftsmanship Details
Forged by geological hydrothermal processes; features natural crystal growth and tectonic fracturing.
Authentication Indicators
Sectility (gold will dent rather than shatter), high luster in shade, and specific gravity relative to size. Warning: Pyrite or Mica can mimic this appearance; hardness test recommended.
Origin & Maker
Natural geological formation; Likely sourced from an eluvial or lode deposit.
Era & Period
Contemporary discovery; Geological formation likely millions of years old (Precambrian to Cenozoic).
Age Estimate
Natural geological age; recently extracted from the earth.
Cultural Significance
Representative of high-grade ore; signifies the 'Gold Rush' heritage and the primary form of wealth extraction throughout history.
Condition Notes
All-natural condition; raw surface with visible dirt and mineral inclusions. Grade: Raw Specimen.
Value Estimate
Highly dependent on the actual gold volume; specimen value often carries a 20-50% premium over melt value for collectors.
Care & Maintenance
Keep dry; clean only with soft brush and distilled water. Avoid acids that may dissolve the matrix or iron staining if the 'rusty' look is desired for provenance.

Interesting Facts
Gold is often found in quartz veins because both were transported by the same hydrothermal fluids deep in the Earth's crust.
