Auriferous Quartz and Ironstone Gold Ore Specimen
Raw Gold (Ore/Matrix) · Native Yellow Gold
Purity: Likely 20K to 24K (83.3% to 99.9%) for the native gold content within the matrix. Being raw mineral form, the total specimen's purity is low, but the gold particles themselves are naturally high-purity.
Type
Raw Gold (Ore/Matrix)
Purity
Likely 20K to 24K (83.3% to 99.9%) for the native gold content within the matrix. Being raw mineral form, the total specimen's purity is low, but the gold particles themselves are naturally high-purity.
Gold Type
Native Yellow Gold
Weight
350 - 500 grams (total specimen weight). Actual gold content is likely measured in grains or a few grams once extracted.
Description
A rugged mineral specimen consisting of an iron-rich oxide matrix (ironstone) hosted by crystalline quartz. This is classic 'hard rock' gold ore where gold is typically trapped within the quartz veins or at the contact point of the iron-stained host rock.
Key Features
Heavy iron oxidation, crystalline quartz structures, and vuggy (pitted) surface texture typical of hydrothermal gold deposits.
Color & Finish
Deep reddish-brown (limonite/hematite) ironstone with white to translucent crystalline quartz. Gold particles, if visible, would be rich buttery yellow.
Hallmarks & Stamps
None; natural specimen. No man-made markings.
Dimensions Estimate
8 cm x 6 cm x 4 cm; roughly hand-sized specimen.
Gemstones & Inlays
Translucent quartz crystals (the matrix) and iron-rich mineral inclusions; no precious cut gemstones.
Clasp & Closure
Not applicable; raw mineral specimen.
Chain & Links
Not applicable; solid rock matrix with crystalline growth.
Craftsmanship Details
Natural geological formation; hydrothermal deposition resulting in unique crystalline lattice and mineral layering.
Authentication Indicators
Natural quartz-gold association, presence of gossan (iron hat) indicators, and crystalline structure; lacks the 'perfect' appearance of synthetic fakes.
Origin & Maker
Likely from a lode deposit/hard rock mine; specific origin unknown but resembles high-sulfide or iron-head ore from regions like Africa, Australia, or the Americas.
Era & Period
Contemporary Geological/Natural (formed over millions of years).
Age Estimate
Geological age: millions of years; Recovery date: Recent (Contemporary).
Cultural Significance
Represents the primary source of human wealth; the physical starting point of the gold standard and global jewelry trade.
Condition Notes
Natural raw state; unrefined. Surface shows minor dirt and weathering consistent with recent extraction (Grade: Raw Mineral).
Value Estimate
Primarily determined by 'gold per ton' yields. As a collector's specimen: $50-$200 depending on visible gold. Industrial value: dependent on assay results.
Care & Maintenance
Keep dry to prevent further oxidation of iron minerals; clean only with soft brush and water; avoid acids which may dissolve the matrix.
Similar Items
Copper ore or Pyrite (Fool's Gold); distinguished by gold's malleability and the specific density of the host quartz.
Interesting Facts
Most gold is not found as large nuggets but as microscopic particles within rocks like this, requiring crushing and chemical extraction to reveal.
