Not applicable (Rough uncut stone) Cut
Carat
Estimated 8.5 to 10.5 carats based on relative finger size and thickness
Color
Near colorless to light brownish tint (approx. H-J range)
Clarity
Included / I1 to I2 equivalent due to internal striations and surface features
Shape
Rough crystal / Irregular uncut fragment
Overall Assessment
An interesting, substantial natural rough crystal specimen holding potential for a custom-cut faceted diamond after professional evaluation and sawing.
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low due to lack of faceted geometry and rough surface texture
Fire
Minimal to none in current rough state
Scintillation
Absent due to unpolished and unfaceted surfaces
Proportions
Not applicable to rough crystals
Symmetry
Natural crystal symmetry (Asymmetric rough form)
Polish
Natural rough crystal faces (Unpolished)
Fluorescence
Cannot be determined without UV testing (Likely Faint to None)
Inclusions
Heavy internal graining, growth lines, and mineral inclusions visible
Blemishes
Natural surface etching, trigons, and rough skin textures
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No treatments detected; completely untreated natural rough
Estimated Value
Varies widely depending on cutting yield, estimated between $1,500 - $3,500 as rough mineral specimen
Certification Estimate
GIA or local geological authority would issue a rough diamond report
Investment Potential
Speculative value based on potential cut yield after professional sawing and faceting

Setting Suggestions
Can be custom-set in its organic rough form using bezel or prong settings with yellow or rose gold
Care & Maintenance
Store separately to prevent scratching other softer stones; clean gently with warm soapy water and soft brush
