Natural Alluvial Gold Nugget
Raw Gold Nugget · Natural Native Gold; deep yellow alloy with inherent silver (electrum) and iron staining.
Purity: Typically 20K to 22K (83%-92% pure); natural gold is never 24K as it contains trace silver and copper.

Gold Type
Natural Native Gold; deep yellow alloy with inherent silver (electrum) and iron staining.
Weight
Estimated 0.5 - 1.5 grams based on finger-tip scale for comparison.
Description
A raw, flattened alluvial gold nugget featuring a high-luster surface and characteristic 'dimpling' caused by stream tumble and geological pressure. The piece exhibits a rich, deep yellow color indicative of high purity, with dark iron-rich host material still visible in the pitted textures.
Key Features
Water-worn rounded edges, botryoidal-like surface textures, and characteristic high-density brilliance.
Color & Finish
Brilliant brassy-yellow with brownish-red iron oxide patination in deep recesses; natural water-worn/pitted finish.
Hallmarks & Stamps
None; as a raw geological specimen, it lacks man-made stamps or hallmarks.
Dimensions Estimate
Approx. 10mm x 8mm x 2mm; categorized as a small 'picker' nugget.
Gemstones & Inlays
None; however, the specimen shows possible quartz host rock inclusions in the crevices.
Clasp & Closure
Not applicable; raw specimen.
Chain & Links
Not applicable; raw specimen.
Craftsmanship Details
Nature-formed; the 'craftsmanship' is dictated by the distance the gold traveled in a river and the pressure of the earth.
Authentication Indicators
Irregular crystalline structure, metallic luster that does not flake (unlike pyrite), and heavy sectional density.
Origin & Maker
Natural origin; likely a placer deposit from regions like Alaska, Australia, or California.
Era & Period
Geological/Modern Discovery; specimens like this are found in contemporary placer mining.
Age Estimate
Natural formation occurs over millions of years; recovery likely within the last 10 years.
Cultural Significance
Symbol of the frontier and gold rushes; highly prized in 'raw' jewelry to signify luck and adventure.
Condition Notes
Very Good (Natural State); shows typical environmental abrasion from water transport with no signs of smelting or artificial alteration.
Value Estimate
Melt value + 10-30% specimen premium; natural nuggets trade above spot price due to rarity.
Care & Maintenance
Clean with a soft brush and warm soapy water; avoid harsh chemicals that could strip natural patination; store in a gem jar.
Similar Items
Iron Pyrite (Fool's Gold) which is brittle and cubic; Mica which is flaky; or gold-plated river rocks which lack density.
Interesting Facts
Over 95% of the world's gold has been melted down; finding natural nuggets is rare as they represent less than 2% of total gold found.
