Non-Diamond (Likely Amethyst/Quartz)
Non-Diamond (Likely Amethyst/Quartz) · Rough/Uncut Natural Crystal
N/A (Uncut raw specimen) Cut
Carat
Estimated 30 - 50 carats based on size relative to carpet fibers
Color
N/A (Exhibits zones of light to medium violet/purple)
Clarity
N/A (Translucent with heavy internal inclusions)
Shape
Rough/Uncut Natural Crystal
Overall Assessment
This object is not a diamond. It is a raw, low-clarity specimen of purple quartz, commonly known as Amethyst. It lacks the refractive index, adamantine luster, and crystal structure of either raw or cut diamonds.
Cut Quality
N/A (Uncut raw specimen)
Brilliance
Very Low (Waxy to vitreous luster, not diamond-like)
Fire
None detected
Scintillation
Negligible
Proportions
N/A (Irregular rocky geometry)
Symmetry
N/A (Asymmetric natural formation)
Polish
N/A (Rough natural surface)
Fluorescence
Indeterminable without UV light
Inclusions
Heavy internal fracturing, color zoning, and cloudy veining consistent with quartz
Blemishes
External pitting, jagged edges, and surface abrasions
Origin
Likely Brazil or Uruguay (typical sources for common amethyst quartz)
Treatment Detection
Possibly heat-treated, though appears natural and low-grade
Estimated Value
$5.00 - $15.00 USD (Specimen value only)
Certification Estimate
Not applicable for diamond labs; potentially a mineral identification report
Investment Potential
None (Common decorative mineral)
Similar Diamonds
None (This is a silicate mineral, not carbon-based diamond)
Setting Suggestions
Wire-wrapped pendant or tumbled collector's stone
Care & Maintenance
Avoid harsh impacts and long-term direct sunlight to prevent color fading
Interesting Facts
The purple color in quartz is caused by irradiation and trace amounts of iron
