Natural rough diamond
Natural rough diamond · Uncut rough octahedral crystal
Not applicable (Rough, unpolished stone) Cut
Carat
Estimated 1.5 to 2.5 carats
Color
Near-colorless with a slight brownish/yellowish tint (Estimated G-I range)
Clarity
Estimated SI1 to SI2 based on visible internal features in the rough form
Shape
Uncut rough octahedral crystal
Overall Assessment
A fascinating, natural rough diamond crystal displaying classic octahedral formation traits. Its ultimate value and beauty will depend heavily on the planning and cutting process if faceted into a polished gemstone
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Low to moderate due to rough, unpolished surfaces preventing optimal light refraction
Fire
Limited due to lack of standard facet angles
Scintillation
Minimal sparkle; reflects light diffusely off natural crystal faces
Proportions
Natural crystal habit with octahedral faces, no standard facet proportions applicable
Symmetry
Natural octahedral crystal symmetry, slightly distorted
Polish
Natural crystal faces (trigons and natural growth markings present)
Fluorescence
Indeterminate without UV testing (Likely Faint to Medium Blue if present)
Inclusions
Internal crystal inclusions, clouds, and feather fractures visible
Blemishes
Natural surface pitting, trigons, and rough skin characteristic of unpolished crystals
Origin
Natural terrestrial origin (African or Canadian rough source likely)
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Varies widely depending on cutting yield, approximately $2,000 to $5,000 USD for rough depending on final cut weight potential
Certification Estimate
GIA or IDEX (Rough diamond evaluation report)
Investment Potential
Moderate to high for collectors of rough stones, highly dependent on the skill of the master cutter who plans the final polished yield

Setting Suggestions
Can be mounted raw/uncut in a bespoke organic bezel or prong setting using yellow gold or platinum for a rustic, earthy look
Care & Maintenance
Clean gently with warm soapy water and a soft brush; protect from harsh impacts since rough stones can have hidden cleavage planes
