Overall Assessment
An interesting raw diamond crystal specimen showing natural geological features, best appreciated in its natural rough form rather than faceted.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low (due to rough surfaces and inclusions)
Fire
Low in current rough state
Scintillation
Minimal until cut and polished
Proportions
N/A for rough crystal specimens

Internal fractures, cloudiness, and crystal growth lines visible
Blemishes
Natural surface etching, rough skin, and growth steps
Origin
Natural rough alluvial or primary pipe deposit
Treatment Detection
No treatments observed; appears completely untreated rough
Estimated Value
Modest value as a mineral specimen; highly dependent on cutting potential
Certification Estimate
GIA or local gemological lab for rough origin certificate
