Natural Alluvial Gold Flake

Raw Gold (Flake/Placer Gold) · Natural Placer Gold; contains natural silver and copper trace alloys.

Purity: Approximately 20K-23K (83% - 96% purity). Natural gold is never 24K pure as it naturally alloys with silver, copper, and iron.

Type

Raw Gold (Flake/Placer Gold)

Purity

Approximately 20K-23K (83% - 96% purity). Natural gold is never 24K pure as it naturally alloys with silver, copper, and iron.

Gold Type

Natural Placer Gold; contains natural silver and copper trace alloys.

Weight

Estimated 0.05 - 0.15 grams (well under 0.1 pennyweight).

Description

An organic, flat alluvial gold flake resting in the palm of a hand. This specimen exhibits the characteristic 'placer' shape, appearing beaten flat by the movement of water and rocks in a stream or river. It has a rich, high-karat yellow color and reflects light with the distinct greasy-metallic luster unique to native gold.

Key Features

Planar geometry, irregular 'jagged' edges smoothed by erosion, and high-density appearance relative to common yellow minerals like pyrite.

Color & Finish

High-luster buttery yellow with a natural metallic sheen. The surface is flattened and water-worn with a micro-pitted texture typical of alluvial deposit items.

Hallmarks & Stamps

None. As a raw geological specimen, it lacks man-made stamps or hallmarks.

Dimensions Estimate

Approximately 4mm x 6mm; extremely thin (sub-millimeter thickness).

Gemstones & Inlays

None; purely metallic mineral specimen.

Clasp & Closure

Not applicable; raw specimen.

Chain & Links

Not applicable; however, the edges show irregular mechanical wear from river travel (tumbling).

Craftsmanship Details

Nature-made; sculpted by hydraulic action and geological pressure.

Authentication Indicators

The lack of cleavage planes, the specific deep yellow hue, and the way the light glints off the irregular surface. Unlike 'Fool's Gold' (Pyrite), it does not show cubic crystalline structures and remains bright in shadow.

Origin & Maker

Natural origin; typically recovered from riverbeds or glacial till. No human maker.

Era & Period

Geological/Contemporary; recently recovered from a secondary placer deposit.

Age Estimate

Geologically millions of years old; recently extracted from the earth.

Cultural Significance

Represents the 'Gold Rush' archetype; the fundamental form of gold that inspired global migrations to California, the Yukon, and Australia.

Condition Notes

Natural state. Grade: Fine Flake. No signs of chemical cleaning or mercury contamination (amalgamation).

Value Estimate

Primarily valued by spot price per gram plus a small 'specimen premium' (shocker/collector value). Likely worth $5-$15 USD depending on current market spot prices.

Care & Maintenance

Store in a small glass 'gem jar' or vial. Avoid vigorous rubbing which can bend the thin edges. Do not use harsh chemicals.

Similar Items

Gold-colored Mica (flakes easily with a fingernail) or Chalcopyrite (more brittle and darker).

Interesting Facts

Most gold flakes have survived a journey of miles from their original 'lode' or vein source, being tumbled in rivers for centuries to reach this flat, thin state.
