Natural Native Gold Ore Specimen in Quartz Matrix

Raw Gold (nugget/flake in host rock matrix) · Natural Native Yellow Gold with possible iron-oxide staining (limonite) on the host rock.

Purity: Estimated 20K to 23K (83% - 96% purity). Natural gold is rarely 100% pure and usually contains silver, copper, or iron.

Natural Native Gold Ore Specimen in Quartz Matrix

Type

Raw Gold (nugget/flake in host rock matrix)

Purity

Estimated 20K to 23K (83% - 96% purity). Natural gold is rarely 100% pure and usually contains silver, copper, or iron.

Gold Type

Natural Native Yellow Gold with possible iron-oxide staining (limonite) on the host rock.

Weight

Estimated 2-5 grams total weight; based on visual size, the actual gold content is likely under 0.5 grams.

Description

A raw, unrefined specimen of native gold embedded in its original host matrix. This piece displays the 'hackly' fracture and bright metallic yellow hue characteristic of high-purity natural gold. The gold appears as thin filaments or crystalline structures emerging from a brownish-grey rock base, showcasing the raw beauty of precious metal before industrial processing.

Key Features

Crystalline structure, distinct metallic luster that does not tarnish, lack of cleavage in the gold portions, and high density relative to the host rock.

Color & Finish

Rich buttery yellow with a metallic luster. The surface is naturally irregular, crystalline, and hackly. Host rock shows matte brown and grey mineral textures.

Hallmarks & Stamps

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

Dimensions Estimate

Approximately 10mm x 15mm; small 'thumbnail' sized specimen suitable for mineral collectors.

Gemstones & Inlays

None. The specimen consists of metallic gold inclusions within a host matrix of quartz/sulfides.

Clasp & Closure

Not applicable; raw mineral specimen.

Chain & Links

Not applicable; raw mineral specimen with irregular, sharp, and jagged edges.

Craftsmanship Details

N/A; Naturally formed via hydrothermal or magmatic processes. No human craftsmanship involved.

Authentication Indicators

Sectility (gold can be cut or deformed without shattering unlike pyrite), lack of tarnishing, and the specific 'buttery' yellow color. Pyrite ('Fool's Gold') would appear more brassy and brittle.

Origin & Maker

Natural occurrence; likely sourced from a hard-rock mine or alluvial deposit. No maker (nature-made).

Era & Period

Geological/Contemporary discovery. Formed millions of years ago, but recently extracted.

Age Estimate

Geological age: Millions of years. Extraction age: Contemporary.

Cultural Significance

Represents the 'Gold Rush' heritage and the fundamental human drive for exploration and mining that has shaped global economies.

Condition Notes

Raw condition. Shows typical extraction wear including fractured rock edges and some crushing of the gold filaments. Grade: Natural Mineral Specimen.

Value Estimate

Value is speculative. Melt value is likely $15-$40 USD; however, as a collector specimen, it may command $50-$100 USD depending on the 'eye appeal' of the gold presentation.

Care & Maintenance

Do not use ultrasonic cleaners as they may break the host rock. Clean with soft brush and distilled water only. Store in a padded gem jar to prevent gold filaments from flattening.

Similar Items

Iron Pyrite (Fool's Gold), Chalcopyrite, or gold-plated quartz. Differences include hardness, streak color (gold has a yellow streak), and malleability.

Interesting Facts

Most gold is found as microscopic particles; specimens with visible gold like this represent a tiny fraction of the world's gold supply and are often worth more to collectors than their melt value.
