Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral or slightly rounded rough crystal form
Not applicable (Rough, unpolished crystal state) Cut
Carat
Estimated 0.75 - 1.25 carats based on visual size relative to human fingertips
Color
Estimated near-colorless to light brown/grey (G-J range equivalent)
Clarity
Estimated SI1 - SI2 (Contains visible internal inclusions and cloudy patches)
Shape
Uncut octahedral or slightly rounded rough crystal form
Overall Assessment
An interesting and genuine natural rough diamond crystal displaying characteristic octahedral/rounded morphology, ideal for a custom designer piece or precision cutting.
Cut Quality
Not applicable (Rough, unpolished crystal state)
Brilliance
Low in current rough state; requires proper faceting to exhibit white light reflection
Fire
Minimal dispersion in rough form; dependent on future cut proportions
Scintillation
Absent in rough state
Proportions
Natural crystal morphology, highly dependent on how a future master cutter plans the cut
Symmetry
Natural crystal symmetry showing octahedral growth characteristics
Polish
Natural rough crystal faces (no man-made polish)
Fluorescence
Indeterminate from visual inspection alone (typically tested under UV)
Inclusions
Cloudy regions, small crystal inclusions, and internal feathers typical of rough stones
Blemishes
Natural surface trigons, etching, and rough skin typical of alluvial or primary deposit rough
Origin
Likely natural primary kimberlite or secondary alluvial deposit
Treatment Detection
No treatments detected; appears completely untreated and natural
Estimated Value
Varies significantly depending on final yield after cutting, roughly $500 - $1,500 USD for the rough stone
Certification Estimate
GIA or similar major lab would issue a Rough Diamond Description Report or Kimberley Process certification
Investment Potential
Moderate; value is speculative until cut, polished, and certified
Similar Diamonds
Comparable natural rough diamond crystals sold to lapidaries and custom jewelry designers
Setting Suggestions
Can be set raw in an organic, rustic bezel setting using yellow or white gold for a modern raw-diamond aesthetic
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their geological history, often showcasing natural growth marks like triangular etchings called trigons
