Non-Diamond / Quartz Geode Fragment
Non-Diamond / Quartz Geode Fragment · Rough / Uncut Natural Mineral
N/A (Uncut mineral specimen) Cut
Carat
Estimated 5-10 carats (based on approximate 15mm width)
Color
Opaque Brownish-Orange / Rusty Yellow
Clarity
Opaque (contains significant matrix and crystal clusters)
Shape
Rough / Uncut Natural Mineral
Overall Assessment
The object shown is not a diamond. It is a natural mineral specimen, likely a fragment of a quartz or calcite geode with iron oxide staining that gives it a brownish-yellow hue. It lacks the crystal structure, luster, and refractive properties of a diamond.
Cut Quality
N/A (Uncut mineral specimen)
Brilliance
Very Low (Sub-vitreous to earthy luster)
Fire
None
Scintillation
Minimal (Small surface crystal reflections only)
Proportions
N/A
Symmetry
N/A (Natural jagged formation)
Polish
N/A (Natural rough surface)
Fluorescence
Unknown / Likely None
Inclusions
Heavy iron oxide staining and host rock matrix
Blemishes
External weathering and structural fractures
Origin
Likely sedimentary or volcanic terrestrial environment (Quartz/Calcite origin)
Treatment Detection
None detected; appears to be a raw natural mineral fragment
Estimated Value
Nominal / Minimal (Value is ornamental or educational)
Certification Estimate
Ineligible for GIA/AGS diamond grading; would be identified as a mineral specimen.
Investment Potential
None as a gemstone; primarily of curiosity value
Similar Diamonds
None (This is a druzy quartz or calcite fragment, not a diamond)
Setting Suggestions
Wire-wrapped pendant or kept as a loose mineral specimen
Care & Maintenance
Avoid harsh chemicals; clean with soft brush and water if needed to remove dust.
Interesting Facts
The specimen displays 'druzy' crystal growth, common in geodes found in limestone or volcanic pockets.
