Raw Placer Gold Dust (Alluvial)
Raw Gold (dust, flour, or fine flake) · Natural Yellow Gold with varying concentrations of silver (electrum) and environmental iron staining.
Purity: Likely 20K to 23K (83% - 96% gold content); raw gold is never 24K pure in nature as it is naturally alloyed with silver, copper, and iron.
Type
Raw Gold (dust, flour, or fine flake)
Purity
Likely 20K to 23K (83% - 96% gold content); raw gold is never 24K pure in nature as it is naturally alloyed with silver, copper, and iron.
Gold Type
Natural Yellow Gold with varying concentrations of silver (electrum) and environmental iron staining.
Weight
Trace amount; likely less than 0.1 to 0.2 grams pictured on fingertips. Mass is insufficient for substantial valuation without larger volume.
Description
This is raw placer gold dust, the result of natural erosion where gold has been washed from a lode source into a riverbed or soil. It appears as extremely fine particles, often referred to as 'flour gold.' In this state, the gold is unrefined and mixed with local sediment.
Key Features
Extremely high density compared to surrounding minerals; lack of tarnish (though it may have 'iron frosting'); irregular, granular shapes visible under magnification.
Color & Finish
Dull, dark metallic yellow to brassy brown; raw gold dust lacks the luster of refined gold due to surface oxides and microscopic dirt.
Hallmarks & Stamps
None; raw geological material.
Dimensions Estimate
Particle size ranges from microscopic to 'flour' gold (under 0.5mm).
Gemstones & Inlays
None; likely contains mineral impurities such as magnetite (black sand) or quartz micro-fragments.
Clasp & Closure
None (raw material).
Chain & Links
None (raw material).
Craftsmanship Details
N/A; Mother Nature is the craftsman of these geological particles.
Authentication Indicators
Color consistency when rubbed; high weight-to-volume ratio (though hard to tell at this scale). Red flag: Many 'dust' samples sold on the street are actually brass filings or iron pyrite (fool's gold).
Origin & Maker
Naturally occurring; geographic origin typically artisanal or small-scale mining (ASM) sites, frequently in regions like West Africa or South America based on visual context.
Era & Period
Geological/Modern Extraction.
Age Estimate
Geologically ancient (millions of years); recently extracted from alluvial deposits.
Cultural Significance
Represents the primary source of income for millions of artisanal miners globally and is the foundational stage of the global gold supply chain.
Condition Notes
Raw, unrefined, and 'dirty' state. Contains significant environmental impurities that would be removed during the smelting process.
Value Estimate
Negligible in this quantity. Market value is calculated at Spot Price minus a 20-30% 'refinery spread' for unrefined material due to unknown purity and smelting costs.
Care & Maintenance
Store in a glass vial or sealed 'snuffer bottle.' Should be processed using a gold pan or mercury-free retort to consolidate into a button.

Interesting Facts
It takes approximately 31,103 milligrams of gold dust to make just one troy ounce. Much of the world's historic gold was first found in this humble dust form in riverbeds.
