Natural rough diamond crystal
Natural rough diamond crystal · Rough octahedron/irregular crystal form
Not applicable (rough un-cut stone) Cut
Carat
Estimated 2.0 to 3.5 carats
Color
Estimated near-colorless to faint yellow (H-J range)
Clarity
Estimated included (I1-I2) due to visible internal fractures and mineral inclusions
Shape
Rough octahedron/irregular crystal form
Overall Assessment
A fascinating specimen of a natural rough diamond crystal, showcasing raw geological characteristics before human intervention and faceting.
Cut Quality
Not applicable (rough un-cut stone)
Brilliance
Limited in rough form, exhibits vitreous to adamantine luster on windows
Fire
Present in transparent windows where light disperses
Scintillation
Minimal to none due to lack of faceted surfaces
Proportions
Natural rough proportions, requires planning for cutting
Symmetry
Natural octahedral/distorted crystal symmetry
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual inspection alone
Inclusions
Internal cleavage planes, feathers, and a distinct dark mineral crystal inclusion
Blemishes
Natural surface pitting, rough skin, and growth features
Origin
Alluvial or primary kimberlite deposit origin
Treatment Detection
No treatments detected; appears completely untreated and natural
Estimated Value
Varies widely based on cutting potential, roughly $1,000 to $3,000 USD as rough
Certification Estimate
GIA or similar major lab would grade post-cutting
Investment Potential
Moderate as a collector specimen, higher if successfully cut into a high-yield polished diamond
Similar Diamonds
Typical 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, or polished into a brilliant cut
Care & Maintenance
Store separately to avoid scratching other gems; clean gently with warm soapy water and a soft brush
Interesting Facts
Shows natural growth features such as striations and triangular etch marks (trigons) common on octahedral faces
