Unrefined Natural Placer Gold Flakes and Dust
Raw Gold (nugget, dust, and flake) · Natural Yellow Gold with native silver and copper alloys.
Purity: Estimated 85% to 92% (approx. 20K to 22K purity). Natural gold is never 24K and typically contains silver and copper impurities.

Purity
Estimated 85% to 92% (approx. 20K to 22K purity). Natural gold is never 24K and typically contains silver and copper impurities.
Gold Type
Natural Yellow Gold with native silver and copper alloys.
Weight
Indeterminate from image; visually appears to be a small concentrate of fine particulates (sub-gram to several grams possible depending on depth).
Description
A collection of natural unrefined gold particulates, commonly referred to as flour gold and small flakes. These specimens represent gold in its native state, likely recovered through panning or sluicing. The material displays the characteristic irregular geometry and high-refractive yellow luster that distinguishes native gold from pyrite or mica.
Key Features
Heterogeneous particle sizes, irregular jagged morphology, and high-density settling within earthy matrix.
Color & Finish
Deep buttery yellow with natural metallic luster; textured, granular, and porous surfaces typical of alluvial deposits.
Hallmarks & Stamps
None; raw gold has no hallmarks. Authentication relies on specific gravity and metallurgical testing.
Dimensions Estimate
Particles range from micron-sized dust to 1-2mm small flakes.
Gemstones & Inlays
None; presence of earthy host rock or quartz matrix likely mixed with particulates.
Clasp & Closure
None (raw specimen).
Chain & Links
N/A - Non-structural raw material.
Craftsmanship Details
Natural geological formation; shaped by water erosion and hydraulic transport in stream beds.
Authentication Indicators
Color consistency under varying light, lack of crystal cleavage (suggesting ductility), and high contrast against darker host material.
Origin & Maker
Unknown geographic origin; nature-sourced via alluvial or eluvial weathering.
Era & Period
Geological (Contemporary recovery of ancient deposits).
Age Estimate
Geological age: Millions of years; Recovery date: Contemporary (21st Century).
Cultural Significance
Historical basis for currency and the 'Gold Rush' eras of the 19th century; represents the raw wealth of the earth.
Condition Notes
Raw/Unprocessed; contains significant amounts of sediment, sand, and non-auriferous mineral matter.
Value Estimate
Valued at current spot price minus roughly 10-20% for refining costs and impurities, unless sold as a geological specimen with a 'provenance' premium.
Care & Maintenance
Keep in a sealed glass vial or assay jar to prevent loss of fine particles; do not use chemical cleaners as they may react with impurities.

Interesting Facts
Most gold used in jewelry was once in this form. Approximately 80% of the world's accessible gold has already been mined.
