Natural Alluvial Gold Flakes and Flour Gold in Black Sand Concentrate
Raw Gold (dust, flakes, and flour gold) · Natural Yellow Gold. The color is a deep, rich buttery yellow, which is characteristic of high-purity native gold that has had surface impurities leached away by water.
Purity: Likely 20K to 23K (83% - 96% purity). Natural gold found in alluvial deposits is rarely 24K pure as it is naturally alloyed with silver and copper during formation.

Type
Raw Gold (dust, flakes, and flour gold)
Purity
Likely 20K to 23K (83% - 96% purity). Natural gold found in alluvial deposits is rarely 24K pure as it is naturally alloyed with silver and copper during formation.
Gold Type
Natural Yellow Gold. The color is a deep, rich buttery yellow, which is characteristic of high-purity native gold that has had surface impurities leached away by water.
Weight
Estimated 0.5 to 2.0 grams based on visible surface area. In a gold pan, a 'strong showing' of flour gold like this often represents a small fraction of a troy ounce.
Description
A stunning 'tail' of fine alluvial gold resting in the crease of a blue plastic gold pan. The gold is accompanied by heavy black sand concentrates (magnetite), which indicate a successful 'clean up' phase of prospecting. The visual shows a high concentration of fine particles, often referred to as 'color' in the bottom of the pan.
Key Features
High density settling, 'tailing' effect in the pan, distinct yellow contrast against blue plastic and black magnetite sand.
Color & Finish
Vivid high-luster yellow with a natural metallic sheen. The 'finish' is naturally water-worn, showing rounded edges on larger flakes and a microscopic granular texture on the 'gold flour'.
Hallmarks & Stamps
None. As raw, unrefined mineral specimens, there are no government assay marks or maker stamps.
Dimensions Estimate
Flakes range from 0.5mm to 1.5mm (sub-millimeter 'flour' gold). The concentrate strip shown in the pan is approximately 4-6 inches in length.
Gemstones & Inlays
None, though naturally occurring heavy minerals like magnetite, hematite (black sands), and potentially garnets are present in the matrix.
Clasp & Closure
Not applicable. Raw minerals.
Chain & Links
Not applicable. Individual distinct particles.
Craftsmanship Details
Natural water-erosion craftsmanship. The particles are smoothed and flattened by the hydraulic action of river currents and tumbling rocks over centuries.
Authentication Indicators
The way the gold 'hangs' in the corner of the pan despite the water flow indicates its high specific gravity (approx. 19.3). Pyrite or mica (fool's gold) would wash away more easily.
Origin & Maker
Natural origin; typically found in placer deposits in regions like California, Alaska, the Klondike, or Australia. The 'maker' is geological erosion.
Era & Period
Geological/Contemporary Recovery. This represents gold recently extracted from a stream or river bed through artisanal or recreational prospecting.
Age Estimate
The gold itself is millions of years old; the recovery is modern (21st century).
Cultural Significance
Represents the 'Gold Rush' heritage and the enduring human drive for prospecting and mineral discovery.
Condition Notes
Placer gold in raw, uncleaned state. Includes associated mineral sands. Grade: Raw Mineral Specimen.
Value Estimate
Mainly 'spot price' melt value minus refining costs, approximately $50 - $150 USD depending on the total dry weight and current market rates for 22K raw gold.
Care & Maintenance
Store in a glass 'sniffer' bottle or vial. Can be cleaned with a mild solution of dish soap to remove natural oils or dirt; avoid harsh chemicals that might dissolve associated minerals if kept as a specimen.

Interesting Facts
Gold flour is so fine that it can actually float on the surface tension of water if it becomes dry, requiring 'wetting agents' or 'Jet Dry' to keep it submerged during panning.
