Raw Gold (Nugget/Specimen in Matrix) · Native Yellow Gold (natural alloy, typically containing silver and trace copper)
Purity: Approximately 18K to 23K (75-97% pure) in its native state
Type
Raw Gold (Nugget/Specimen in Matrix)
Purity
Approximately 18K to 23K (75-97% pure) in its native state
Gold Type
Native Yellow Gold (natural alloy, typically containing silver and trace copper)
Weight
3 to 8 grams total specimen weight
Description
A high-quality specimen of native gold embedded within a silicate matrix, likely quartz. The gold displays a dendritic or leafy habit with a rich, buttery yellow saturation characteristic of high-purity natural gold. The contrast between the metallic gold and the duller, translucent host rock makes it a desirable mineralogical specimen.
Key Features
Crystalline structure, high metallic luster, and heterogeneous distribution within the host rock
Color & Finish
Deep brassy yellow with a high metallic luster and natural crystalline texture
Hallmarks & Stamps
None (Natural geological specimen; no man-made markings)
Dimensions Estimate
15mm x 12mm x 8mm (Roughly the size of a thumbnail)
Gemstones & Inlays
Natural Quartz and host rock inclusions; no faceted gemstones
Clasp & Closure
None (Natural rough specimen)
Chain & Links
N/A (Non-jewelry form; irregular natural crystalline structure)
Craftsmanship Details
N/A (Naturally occurring; detailed by geological pressure and hydrothermal fluid activity)
Authentication Indicators
Sectility (gold can be cut rather than shattered), lack of cleavage, and specific high-density luster
Origin & Maker
Unknown geographic origin; likely from a lode deposit/hard rock mine
Era & Period
Contemporary Geological Specimen (Natural formation over millions of years)
Age Estimate
Millions of years old (geological formation)
Cultural Significance
Represents the primary source of wealth and the target of 'gold rushes' throughout history.
Condition Notes
Natural raw state; exhibits rugged edges and expected host rock fragmentation (Raw Grade)
Value Estimate
Collector value of $150–$400, primarily based on specimen aesthetics rather than just melt weight
Care & Maintenance
Keep in a protective display jar; avoid harsh chemicals that could dissolve the matrix

Interesting Facts
Gold is one of the few elements found in its 'native' or pure form in nature, rather than as an oxide floor.
