Purity: Estimated 75% to 92% (18K to 22K) natural purity
Type
Raw Gold (Nugget)
Purity
Estimated 75% to 92% (18K to 22K) natural purity
Gold Type
Natural Yellow Gold with iron/quartz host rock matrix
Weight
Estimated 3 to 7 grams (0.1 to 0.22 troy ounces)
Description
A raw, water-worn natural gold nugget recovered from a placer deposit. The specimen exhibits a characteristic 'rough' texture common in finds close to the lode source. It features a visible mixture of high-purity gold interwoven with its original host matrix, giving it a bi-color appearance of metallic yellow and dark earthen tones. Its rounded edges suggest significant time spent tumbling in water, yet it retains enough craggy detail to be highly desirable for mineral collectors.
Key Features
Organic crystalline structure, high density-to-volume ratio, and unique host-rock inclusions
Color & Finish
Deep buttery yellow with dark brown-black iron oxide staining and quartz inclusions
Hallmarks & Stamps
None (natural unrefined specimen)
Dimensions Estimate
Approximately 12mm x 8mm x 5mm
Gemstones & Inlays
Natural mineral inclusions (likely Iron Stone or Quartz)
Clasp & Closure
Not Applicable
Chain & Links
Not Applicable (Solid mineral formation)
Craftsmanship Details
Natural geological crystallization and fluvial erosion (nature-formed).
Authentication Indicators
Specific gravity (feels heavy for its size), lack of repetitive tool marks, characteristic color of high-karat natural alloy, non-magnetic properties.
Origin & Maker
Placer deposit (likely stream or riverbed), Maker: Mother Nature
Era & Period
Geological Formation (Pleistocene to Holocene deposit)
Age Estimate
Formed millions of years ago; recently unearthed or recovered
Cultural Significance
Gold nuggets represent the 'Gold Rush' eras of California and the Klondike, symbolizing rugged individualism and the potential for instant wealth.
Condition Notes
Natural condition, uncleaned; exhibits minor oxidation and surface sediment consistent with recent recovery.
Value Estimate
$250 - $600 USD (Value carries a 'nugget premium' of 10-30% over the raw spot price of gold)
Care & Maintenance
Clean with mild soap and water only; avoid harsh chemicals that could dissolve the matrix. Store in a soft-lined container.

Interesting Facts
Less than 2% of the world's gold is found in nugget form; the rest is microscopic or mined as ore. Findings this large are significantly rarer than smaller 'flour gold'.
