Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral or irregular rough crystal form
Not applicable (uncut rough crystal) Cut
Carat
Estimated 1.5 to 2.5 carats based on visual scale in fingers
Color
Near-colorless to faint brown tint (approx. G-I range)
Clarity
Included (SI2 to I1 estimated due to visible internal feathering and inclusions)
Shape
Uncut octahedral or irregular rough crystal form
Overall Assessment
An intriguing, natural rough diamond crystal offering excellent potential for custom lapidary work or unique organic jewelry design
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Limited in rough form; will exhibit brilliance only after proper cutting and polishing
Fire
Obscured by rough surface texture; dispersion will increase significantly post-cut
Scintillation
Absent in rough state; depends entirely on future pavilion and crown facet arrangement
Proportions
Natural crystal morphology; requires professional cutting assessment for optimal yield
Symmetry
Natural asymmetrical rough growth form
Polish
Natural crystalline faces and growth striations (trigons potentially present)
Fluorescence
Cannot be determined without UV lamp testing (likely None to Faint)
Inclusions
Visible internal feathers, clouds, and potential mineral inclusions typical of rough stones
Blemishes
Natural surface textures, pitting, and rough skin characteristic of unpolished diamonds
Origin
Likely primary alluvial or kimberlite pipe deposit origin
Treatment Detection
No treatments detected; exhibits natural untreated rough characteristics
Estimated Value
Varies widely depending on cutting yield, final clarity, and color retention post-polishing
Certification Estimate
GIA or AGS if submitted as rough, though typically certified after cutting
Investment Potential
High speculative potential depending on the cutter's ability to maximize weight and clarity grade
Similar Diamonds
Comparable to unpolished run-of-mine diamond parcels or industrial/gem-grade rough stones
Setting Suggestions
Can be mounted raw in a bespoke organic bezel setting, or custom-cut into a round or fancy shape for traditional jewelry
Care & Maintenance
Store separately to avoid scratching other stones; clean gently with warm soapy water and a soft brush
