Natural rough gemstone / Crystal specimen
Natural rough gemstone / Crystal specimen · Uncut raw crystal (Irregular / Rough form)
Not Applicable (Rough, uncut stone) Cut
Carat
Estimated 10.0 to 15.0 carats based on visual scale relative to hand-held perspective
Color
Near-colorless to very light brown/yellow tint in rough form
Clarity
I1 to I3 in rough, significant internal feathering and structural inclusions
Shape
Uncut raw crystal (Irregular / Rough form)
Overall Assessment
This is an interesting, natural rough crystalline specimen showing characteristic raw texture and cleavage planes, best suited for mineral collections or raw jewelry rather than high-end investment faceted stones.
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low in rough state due to unpolished surfaces and internal fracturing
Fire
Minimal dispersion visible externally due to lack of standard faceted angles
Scintillation
Poor sparkle until properly cut and polished by a lapidary
Proportions
Not Applicable for rough crystals (variable dimensions)
Symmetry
Natural crystal symmetry (Asymmetrical rough form)
Polish
Raw unpolished surface, typical natural crystal faces and fracture planes
Fluorescence
Faint to moderate blue luminescence visible under certain lighting angles
Inclusions
Heavy internal fracturing, cleavage planes, mineral inclusions, and internal cloudiness
Blemishes
Natural surface etching, trigons or growth lines, and rough fracture marks
Origin
Alluvial deposit or primary kimberlitic rough source
Treatment Detection
No visible treatments detected; appears completely untreated natural material
Estimated Value
Nominal value as a mineral specimen or low-grade industrial/ornamental rough diamond ($50 - $200 depending on actual composition)
Certification Estimate
GIA or similar primary lab would grade this as rough mineral specimen; low commercial clarity grade if faceted
Investment Potential
Low investment potential for standard commercial resale; valued primarily as a geological curiosity or specimen piece
Similar Diamonds
Standard run-of-mine industrial or low-clarity gem-quality rough diamond crystals
Setting Suggestions
Wire-wrapped pendant setting or custom raw mineral prong setting to preserve natural shape
Care & Maintenance
Store separately in a fabric-lined box to avoid scratching other materials or fracturing along cleavage planes; clean gently with warm soapy water
Interesting Facts
Rough diamonds display natural crystal growth features like triangular etch marks called trigons, and this specimen shows natural cleavage patterns
