Natural Unrefined Raw Gold Nugget in Quartz Matrix
Raw Gold (Nugget in Host Rock) · Natural Native Yellow Gold Alloy (Silver/Copper traces)
Purity: Estimated 20K to 22K (83% - 92% purity typical for natural nuggets)
Type
Raw Gold (Nugget in Host Rock)
Purity
Estimated 20K to 22K (83% - 92% purity typical for natural nuggets)
Gold Type
Natural Native Yellow Gold Alloy (Silver/Copper traces)
Weight
Undetermined (Total specimen looks to be 1-5 grams based on finger scale)
Description
A raw, unrefined gold specimen still embedded in its primary quartz matrix. The gold displays a bright but slightly brassy luster characteristic of high-purity native gold, featuring a jagged, 'sharp' texture that suggests it has not been tumbled smooth by river travel. It represents gold in its most organic, geological state.
Key Features
Interstitial gold Growth within silicate matrix; crystalline structure; absence of mechanical refining marks.
Color & Finish
Glossy brassy yellow with a crystalline and jagged natural surface
Hallmarks & Stamps
None (Natural geological specimen)
Dimensions Estimate
Approximately 15mm - 25mm in length
Gemstones & Inlays
White Milky Quartz host rock matrix
Clasp & Closure
Not applicable
Chain & Links
Not applicable; crystalline-leaf texture
Craftsmanship Details
Natural geological formation; no human craft involved other than extraction and cleaning.
Authentication Indicators
Characteristic uneven metallic luster; jagged 'hackly' fracture; presence of quartz matrix; non-uniform color. Note: High-quality Pyrite (Fool's Gold) can look similar but fractures differently and is harder.
Origin & Maker
Earth-formed mineral; likely a lode gold deposit origin
Era & Period
Geological Contemporary (Formed over millions of years)
Age Estimate
Millions of years since formation; recently unearthed
Cultural Significance
Symbolizes the 'California Gold Rush' era and modern prospecting; highly valued by mineral collectors for geological rarity over simple melt value.
Condition Notes
Natural/Raw grade with minor surface oxidation and visible host rock attachment.
Value Estimate
$100 - $300 (Value is largely based on the aesthetic 'collector specimen' premium rather than industrial melt weight).
Care & Maintenance
Clean with distilled water and a soft brush; avoid harsh acids that could dissolve the gold-to-matrix bond; store in a protective acrylic case.
Similar Items
Gold-bearing Pyrite (Fool's Gold) or Chalcopyrite; both are harder and more brittle than genuine gold.
Interesting Facts
Unlike river-worn nuggets, lode gold found in quartz stays jagged because it hasn't been smoothed by the abrasive action of water and gravel.
