Natural Alluvial Gold Nuggets and Fines
Raw Gold (nuggets, pickers, and flour gold) · Natural Yellow Gold with varying iron staining and silver-alloy electrum characteristics.
Purity: Approximately 20K to 23K (83% to 97% purity). Natural gold is never 24K; it typically contains silver, copper, and iron impurities based on the local geology.

Type
Raw Gold (nuggets, pickers, and flour gold)
Purity
Approximately 20K to 23K (83% to 97% purity). Natural gold is never 24K; it typically contains silver, copper, and iron impurities based on the local geology.
Gold Type
Natural Yellow Gold with varying iron staining and silver-alloy electrum characteristics.
Weight
Estimated 2 to 5 grams total. The larger nuggets appear to be 0.5g to 1g each, while the fine dust accounts for a fraction of a gram.
Description
A collection of natural alluvial gold specimens ranging from fine 'flour' gold to substantial 'picker' nuggets. These items exhibit the classic rounded edges of water-travelled gold, having been tumbled by river currents and gravity over millennia. The specimens show a rich, high-karat saturation and are resting in a black plastic panning bowl used for gravity separation.
Key Features
Raw crystalline structures, water-worn 'placer' texture, high density relative to the black sand (magnetite/hematite) residue.
Color & Finish
Vivid buttery yellow to dark bronze. Surface finish is raw, water-worn, and pitted with a natural metallic luster and occasional iron-oxide patina.
Hallmarks & Stamps
None. As a raw geological specimen, there are no stamps or maker marks.
Dimensions Estimate
Nuggets range from 3mm to 10mm in length. Fine gold (flour gold) is sub-millimeter in size.
Gemstones & Inlays
None, though some nuggets may have quartz or host rock inclusions typical of lode-source erosion.
Clasp & Closure
Not applicable. Raw minerals/nuggets.
Chain & Links
Not applicable. Raw minerals/nuggets.
Craftsmanship Details
Naturally forged by hydrothermal pressure and eroded by fluvial processes. No human craftsmanship involved.
Authentication Indicators
Sectility (gold can be dented with a needle, unlike pyrite which shatters), extreme density in water, unique irregular organic shapes that are difficult to cast convincingly.
Origin & Maker
Natural origin, likely from a river or stream bed (placer deposit). Maker is 'Mother Nature'.
Era & Period
Contemporary Recovery. Geologically ancient (millions of years old), but recently extracted via placer mining.
Age Estimate
Geological age: 50 million+ years; Recovery age: Modern (21st Century).
Cultural Significance
Gold nuggets drove the global migrations of the 19th century (California, Klondike, and Australian Gold Rushes), fundamentally shaping modern borders and economies.
Condition Notes
Natural/Raw. Grade: Specimen Quality. Minor iron staining and sand adherence typical of uncleaned placer gold.
Value Estimate
Approximately $150 to $350 USD total, predicated on a 'specimen premium' (collector value) which typically sits 10-30% above the current spot gold melt price.
Care & Maintenance
Clean with a soft brush and mild soap. Store in a glass vial or display case. Avoid harsh chemicals that could reacts with trace silver/copper impurities.

Interesting Facts
Over 90% of the world's gold has already been mined. Natural nuggets are actually rarer than high-quality diamonds, as most gold is found as microscopic particles in rock.
