Natural rough diamond / mineral crystal
Natural rough diamond / mineral crystal · Uncut rough / octahedral crystal fragments
Not applicable (Rough uncut stone) Cut
Carat
Estimated 15.0 to 25.0 carats (rough form)
Color
Light yellow to off-white (K-M range)
Clarity
Included (I1-I3 equivalent in rough state)
Shape
Uncut rough / octahedral crystal fragments
Overall Assessment
A substantial natural rough diamond specimen exhibiting typical crystal structures, surface features, and internal characteristics prior to any lapidary processing
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low (due to rough, unpolished surfaces)
Fire
Minimal to none in current rough state
Scintillation
Absent prior to cutting and faceting
Proportions
Uncut crystal proportions, irregular rough geometry
Symmetry
Natural crystal growth symmetry (cubic/octahedral habit)
Polish
Unpolished natural crystal faces and cleavage planes
Fluorescence
Cannot be definitively determined without UV testing
Inclusions
Visible internal clouding, mineral crystals, and feather fractures
Blemishes
Natural surface trigons, etch channels, and rough skin
Origin
Natural alluvial or primary kimberlite pipe deposit
Treatment Detection
No treatments detected; completely natural rough crystal
Estimated Value
Varies widely based on cutting yield and final polished outcome
Certification Estimate
GIA or IGI if submitted as rough for certification and mapping
Investment Potential
Speculative, dependent entirely on potential yield if cut and polished
Similar Diamonds
Comparable to industrial or lower-gem-quality run-of-mine rough diamonds
Setting Suggestions
Can be set raw in organic-style designer jewelry or cut into multiple polished stones
Care & Maintenance
Handle with care to prevent chipping along natural cleavage planes; clean with warm soapy water
Interesting Facts
Displays natural growth steps and cubic crystal habit typical of unworked diamond rough
