Natural Crystalline Native Gold Ore Specimen in Quartz Matrix
Raw Gold (Nugget/Specimen) · Natural Yellow Gold with a rich, buttery luster.
Purity: Approximately 20K to 22K (83% - 92% purity). Natural gold is rarely 100% pure, containing alloys of silver (electrum) or copper.
Type
Raw Gold (Nugget/Specimen)
Purity
Approximately 20K to 22K (83% - 92% purity). Natural gold is rarely 100% pure, containing alloys of silver (electrum) or copper.
Gold Type
Natural Yellow Gold with a rich, buttery luster.
Weight
Approx. 0.5 to 1.5 grams total weight inclusive of host rock.
Description
This is a striking example of native crystalline gold partially embedded in a quartz host rock. The specimen exhibits a dense, hackly texture with brilliant metallic reflections that contrast sharply against the translucent white and reddish-brown iron-stained matrix. Unlike water-worn nuggets, this piece retains its sharp, crystalline structure, suggesting it was recovered directly from a hard-rock vein rather than an alluvial deposit.
Key Features
Sharp crystalline structure, distinct metallic luster that remains bright in shadow, and a high-purity color profile characteristic of native gold rather than pyrite (fool's gold).
Color & Finish
Deep saturated yellow with high metallic luster; the finish is natural, featuring crystalline habits, micro-granules, and a rough, unworked surface typical of raw specimens.
Hallmarks & Stamps
None. Natural raw gold does not contain man-made stamps; it is authenticated via specific gravity, XRF testing, or mineralogical observation.
Dimensions Estimate
Approximately 8mm x 12mm x 4mm; sub-centimeter specimen size.
Gemstones & Inlays
None; however, the gold is embedded in a milky-to-clear Quartz matrix, which is the natural host mineral.
Clasp & Closure
Not applicable (Raw mineral specimen).
Chain & Links
Not applicable (Raw mineral specimen).
Craftsmanship Details
Naturally forged through hydrothermal geological processes where gold-bearing fluids cooled within quartz fissures over millennia.
Authentication Indicators
Characteristic uneven, jagged edges; 'gold' color remains consistent from all angles; density suggests high purity. Red flag check: Pyrite would show perfect cubic edges and a greenish-black streak, which are absent here.
Origin & Maker
Mother Nature. Likely sourced from a lode deposit in regions like California (USA), Australia, or Yukon (Canada).
Era & Period
Geological Formation (Millions of years old); contemporary discovery/collection.
Age Estimate
Formed millions of years ago during hydrothermal mineralization; recently mined or found.
Cultural Significance
Raw gold has been a symbol of wealth and divine power since the dawn of civilization. Within the mining community, 'specimen gold' represents the purest connection between the earth and the final refined product.
Condition Notes
Grade: Natural Specimen. The gold appears well-secured to the matrix. Some iron oxide staining (limonite/hematite) is present, which is common and often desired as proof of natural origin.
Value Estimate
Current melt value of gold content: ~$40-$80. Collector/Specimen value: $150-$300 depending on total gold weight and clarity of crystals.
Care & Maintenance
Clean only with distilled water and a soft brush. Avoid ultrasonic cleaners as they can vibrate the gold out of the fragile quartz matrix. Store in a padded gem jar or display case to prevent friction wear.
Similar Items
Gold-bearing Pyrite (often called 'Fool's Gold') which is more brittle and brassy; Chalcopyrite which has an iridescent tarnish; or Gold-plated Quartz which lacks the internal structural depth seen here.
Interesting Facts
Only about 2% of the world's gold is found in nugget or specimen form; the rest is microscopic gold dust within ore that must be chemically processed. Specimen gold often sells for 2x to 5x the 'melt' price because of its rarity and aesthetic appeal to mineral collectors.
