Overall Assessment
An interesting, natural rough diamond specimen displaying characteristic crystal growth lines and surface textures, offering good potential for a skilled lapidary cutter.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low (Unfaceted rough state)
Fire
Low (Requires facet geometry to display dispersion)
Scintillation
Minimal to none in current rough form
Proportions
Not Applicable for rough stone
Symmetry
Natural crystalline symmetry, distorted octahedron
Polish
Natural crystal face texture (trigons potentially present)
Fluorescence
Cannot be definitively determined without UV testing (Likely None to Faint)
Inclusions
Internal feather fractures, crystal inclusions, and cloud patches visible
Blemishes
Natural surface etch channels, triangular trigons, and rough skin
Origin
Natural African or Canadian primary deposit
Treatment Detection
No evidence of artificial treatment; purely natural rough specimen
Estimated Value
Depends heavily on yield after cutting, approximately $1,500 - $4,000 USD in rough form
Certification Estimate
GIA rough report or GDT (Gemological Diamond Technology)
Investment Potential
Moderate, high risk due to unknown cutting yield and sawing complexity
Similar Diamonds
Standard run-of-mine industrial or commercial grade rough diamond crystals
Setting Suggestions
Can be set raw in a custom organic wire-wrap or bezel setting, though typically destined for cutting and polishing
Care & Maintenance
Store separately to prevent scratching other stones; clean with warm soapy water and a soft brush
Interesting Facts
Rough diamonds look remarkably like ordinary glass or quartz until properly tested with a thermal or electrical conductivity diamond tester
