Natural diamond crystal (uncut, rough form)
Natural diamond crystal (uncut, rough form) · Rough crystal / irregular elongated octahedron fragment
Not applicable (uncut rough stone) Cut
Carat
Estimated 3.5 - 5.0 carats based on visual dimensions
Color
Estimated near-colorless to light yellow tint (G-J range)
Clarity
Included (I1-I3) due to heavy internal fractures and inclusions visible in rough form
Shape
Rough crystal / irregular elongated octahedron fragment
Overall Assessment
An interesting natural rough diamond crystal fragment displaying authentic growth patterns and internal characteristics, ideal for mineral collectors or custom organic jewelry design.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low in current rough state; requires proper cutting and polishing to exhibit brilliance
Fire
Minimal dispersion in current state due to frosted/rough exterior
Scintillation
Poor sparkle until faceted and polished
Proportions
Natural uncut crystal proportions, asymmetrical rough shape
Symmetry
Natural crystal symmetry (distorted octahedral/dodecahedral growth lines)
Polish
Natural rough crystal faces (some trigons or striations visible)
Fluorescence
Cannot be determined without UV testing (likely Faint to Medium)
Inclusions
Numerous internal feathers, fractures, cloud-like inclusions, and mineral grains
Blemishes
Natural surface etching, rough skin, and irregular surface features
Origin
Natural alluvial or primary pipe deposit (African or Canadian origin likely)
Treatment Detection
No visible signs of artificial treatments (untreated natural rough)
Estimated Value
Valued primarily as a mineral specimen or industrial-grade rough, approximately $200 - $500 depending on weight
Certification Estimate
GIA or IGI would grade as an uncertified rough diamond specimen
Investment Potential
Low investment potential as a gemstone unless masterfully cut into a smaller polished diamond
Similar Diamonds
Typical industrial or low-gem grade rough diamond crystals
Setting Suggestions
Best preserved as a raw mineral specimen in a custom organic wire-wrap or bezel setting if kept uncut
Care & Maintenance
Store separately to prevent scratching other materials; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds show natural growth features like striated triangular markings called trigons on their crystal faces
