Purity
Natural Purity (Likely 75%-95% within visible flecks); Unknown overall yield per ton
Gold Type
Natural Native Gold in Milky/Iron-Stained Quartz
Weight
150g - 250g (Total specimen weight including rock matrix)
Description
A rugged, high-contrast mineral specimen featuring crystalline quartz with significant iron-oxide staining. The piece displays a typical 'golden' sheen that may indicate native gold or, more commonly, 'Fool's Gold' (Pyrite) interwoven with the host rock. The specimen shows sharp, angular fractures and a distinct hydrothermal vein structure characteristic of lode deposits.
Key Features
Heavy iron oxidation; quartz crystalline structure; metallic yellow inclusions; jagged 'boxwork' textures
Color & Finish
Vitreous to greasy luster on quartz; metallic yellow on flecks; oxidized reddish-brown iron staining (limonite/hematite)
Hallmarks & Stamps
None; natural geological formation
Dimensions Estimate
Approximately 6cm x 4.5cm x 3cm (hand-held size)
Gemstones & Inlays
Sub-metallic inclusions; massive Quartz mineral matrix; likely Pyrite or Chalcopyrite companion minerals
Clasp & Closure
Not applicable; raw mineral specimen
Chain & Links
Not applicable; rough rock texture with crystalline fractures
Craftsmanship Details
Natural crystalline growth; no human craftsmanship; hydrothermal deposition patterns
Authentication Indicators
Sectility (gold is soft/malleable vs brittle pyrite); lack of crystal faces on yellow bits; specific gravity check recommended
Origin & Maker
Natural geological origin; commonly found in hydrothermal vein deposits (e.g., California, Australia, or West Africa)
Era & Period
Modern Geological Recovery (Holocene epoch context)
Age Estimate
Primary mineralization likely millions of years old; recently extracted
Cultural Significance
Represents the 'Gold Rush' era aesthetics and the fundamental source of all refined gold jewelry.
Condition Notes
Natural Raw Condition (Unprocessed); sharp edges; heavy surface oxidation; some dirt/clay residue in crevices
Value Estimate
Specimen Value: $20 - $100 (depending on verified gold content); Melt Value: Minimal until processed
Care & Maintenance
Keep dry; do not clean with harsh chemicals; handle with gloves to prevent skin oils from dulling metallic luster
