Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic growth features and yellow tint, offering potential either as a unique raw specimen or for professional cutting and faceting.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low due to rough, unpolished surface and internal fracturing
Fire
Low in current rough state, depends on final cut
Scintillation
Minimal to none in rough form
Proportions
Natural rough proportions, requires professional mapping and planning for cutting
Symmetry
Natural distorted crystal growth symmetry
Polish
Natural rough crystal faces showing trigons or growth lines, unpolished
Fluorescence
Indeterminate from visual assessment alone, likely Faint to Medium Blue under UV
Inclusions
Internal feather fractures, cloudiness, and crystal inclusions typical of rough stones
Blemishes
Natural surface etchings, pitting, and irregular growth features

Treatment Detection
No treatments detected; appears completely natural and untreated
Estimated Value
Varies widely depending on yield after cutting, roughly $500 to $1,500 USD as a rough specimen
Certification Estimate
GIA or IGI rough diamond evaluation report prior to cutting
Investment Potential
Moderate to high speculative value as a raw collector's crystal or potential high-yield cutter
Similar Diamonds
