Natural Gold-Bearing Ore with Exposed Crystalline Flakes

Raw Gold Ore (Lode Deposit Specimen) · Natural Native Gold; likely alloyed naturally with silver (Electrum) or trace copper.

Purity: Likely 70% to 92% (16K-22K) within the actual gold flakes; the specimen as a whole is mineral rock with trace gold content.

Natural Gold-Bearing Ore with Exposed Crystalline Flakes

Type

Raw Gold Ore (Lode Deposit Specimen)

Purity

Likely 70% to 92% (16K-22K) within the actual gold flakes; the specimen as a whole is mineral rock with trace gold content.

Gold Type

Natural Native Gold; likely alloyed naturally with silver (Electrum) or trace copper.

Weight

Total specimen weight unknown; visible gold content represents a minute fraction of a gram (milligrams).

Description

This is a raw geological specimen of lode gold. It features small, jagged, bright yellow flakes of native gold embedded within a host rock matrix. The rock shows signs of heavy mineralization, with dark red iron oxidation indicating the weathering of sulfide minerals where gold often precipitates. It is a classic 'hard rock' specimen prized by prospectors and mineral collectors for showing 'gold in situ.'

Key Features

Metallic luster that does not change with viewing angle; malleable appearance of the flakes; association with iron-stained quartz/sulfide matrix.

Color & Finish

Vivid buttery yellow metallic flakes contrasting against a dark, hematite-rich or gossanous iron oxide matrix with greyish metallic sulfides.

Hallmarks & Stamps

None; natural geological specimen. No man-made markings.

Dimensions Estimate

Macro view suggests the central gold flake is approximately 1-2mm; the rock fragment appears to be a hand-sized specimen.

Gemstones & Inlays

No gemstones. The matrix appears to consist of quartz, iron oxides (limonite/hematite), and potential sulfides like galena or arsenopyrite.

Clasp & Closure

Not applicable (Raw mineral specimen).

Chain & Links

Not applicable (Raw mineral specimen).

Craftsmanship Details

Natural geological formation via hydrothermal deposition; no human craftsmanship involved.

Authentication Indicators

Sectility (gold can be cut or deformed without shattering unlike pyrite); high-density luster; lack of crystal faces standard in 'Fool's Gold' (Pyrite).

Origin & Maker

Natural Geological Origin. Maker: Nature/Earth's Crust. Common in gold-rich regions like the Mother Lode (California) or Witwatersrand (South Africa).

Era & Period

Modern Discovery; geological age of the deposit likely millions of years (e.g., Paleozoic or Mesozoic era).

Age Estimate

Geological age: millions of years; Time since extraction: Likely contemporary/recent.

Cultural Significance

Represents the 'Gold Rush' heritage of hard-rock mining; symbolizes the raw wealth of the earth before industrial processing.

Condition Notes

Natural and unrefined; the matrix is fractured and crumbly (typical of oxidized ore). Gold flakes remain bright and untarnished.

Value Estimate

Melt value is negligible (less than $5); Specimen value for a collector could range from $20 to $100 depending on the total gold visible and locality.

Care & Maintenance

Keep in a dry environment to prevent further oxidation of the matrix; do not clean with harsh chemicals which may dissolve the host rock; handle carefully as natural gold flakes can be dislodged from the stone.

Similar Items

Pyrite (Fool's Gold) which is brassier and brittle; Chalcopyrite which often has a peacock iridescent tarnish; Mica which is flaky but translucent and non-metallic.

Interesting Facts

Most of the world's gold is found in such tiny particles that it is invisible to the naked eye; a specimen where gold is clearly visible is relatively rare and often worth more as a specimen than the melt value of the gold itself.
