Natural rough diamond crystal
Natural rough diamond crystal · Uncut octahedral / irregular rough crystal
Not applicable (rough, uncut stone) Cut

Carat
Estimated 2.5 to 3.5 carats
Color
Near-colorless to faint yellow (approx. G-I range)
Clarity
Estimated SI1 to SI2 based on visible internal features
Shape
Uncut octahedral / irregular rough crystal
Overall Assessment
A promising natural rough diamond crystal with good clarity potential, well-suited for bespoke organic jewelry or professional cutting to maximize value.
Cut Quality
Not applicable (rough, uncut stone)
Brilliance
Low due to rough, unpolished surface
Fire
Minimal due to lack of faceted geometry
Scintillation
Absent prior to cutting and faceting
Proportions
Not applicable to rough crystals
Symmetry
Natural octahedral crystal symmetry, slightly distorted
Polish
Natural crystal faces (trigons and growth lines visible)
Fluorescence
Cannot be determined without UV testing (estimated None to Faint)
Inclusions
Possible small pinpoints, feathers, and cloud clusters typical of rough diamonds
Blemishes
Natural surface etch marks, striations, and trigons
Origin
Likely from primary pipe deposits (South Africa, Canada, or Russia)
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Varies widely by weight and exact internal clarity; roughly $3,000 - $6,000 USD for rough stone
Certification Estimate
GIA or IGI would classify this as a rough gem-quality diamond
Investment Potential
Moderate, highly dependent on the final yield and cut grade if faceted
Similar Diamonds
Comparable to standard run-of-mine gem-quality octahedral rough crystals
Setting Suggestions
Can be custom-set in a raw diamond organic gold bezel setting, or polished into a brilliant cut
Care & Maintenance
Standard warm soapy water and soft brush; rough stones are durable but edges can chip
Interesting Facts
Shows natural growth features and crystal habit typical of carbon crystallization under high pressure and temperature
