Natural rough diamond specimen
Natural rough diamond specimen · Rough / Uncut crystal fragment
Not applicable (uncut rough specimen) Cut

Carat
Estimated 15-25 carats based on visual scale in hand
Color
Light yellowish-brown / Near-colorless with tint
Clarity
I2-I3 (Included / Industrial grade rough with prominent internal fractures and inclusions)
Shape
Rough / Uncut crystal fragment
Overall Assessment
An interesting, unpolished natural diamond rough specimen displaying typical raw crystal texture and yellowish coloration, suited primarily for mineral collections or specialized artisan jewelry rather than traditional faceted gem use
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low, limited to surface reflection on rough planes
Fire
Minimal dispersion visible due to rough, unpolished surface
Scintillation
Poor, lacking faceted return of light
Proportions
Irregular raw crystal proportions
Symmetry
Natural asymmetric crystal growth
Polish
Raw, unpolished natural crystal faces and fracture surfaces
Fluorescence
Indeterminate from visual assessment alone, likely inert to faint blue
Inclusions
Heavy internal clouding, feather fractures, and potential mineral inclusions
Blemishes
Natural surface etch channels, trigons, and rough skin textures
Origin
Natural alluvial or primary kimberlite/lamproite deposit source
Treatment Detection
No obvious signs of artificial treatment; untreated natural rough
Estimated Value
Low commercial value as industrial rough or mineral specimen
Certification Estimate
Gemological laboratories would classify this as rough mineral specimen; requires cutting for standard GIA grading
Investment Potential
Low investment value; primarily of educational or specimen interest
Similar Diamonds

Setting Suggestions
Best kept as a raw mineral specimen or custom-set in organic wire-wrap jewelry
Care & Maintenance
Store carefully to avoid edge chipping along natural cleavage planes; clean gently with warm soapy water
Interesting Facts
Rough diamonds exhibit natural crystal growth features like triangular etch marks called trigons
