Rough diamond crystal in matrix (Natural)
Rough diamond crystal in matrix (Natural) · Rough / Uncut octahedral or irregular crystal form
Not applicable (Rough uncut stone) Cut

Carat
Estimated 2.50 to 4.00 carats (rough crystal weight)
Color
Near-colorless to light brown tint (Estimated G-J range)
Clarity
Included (I1-I3 range due to visible internal inclusions and fractures in rough form)
Shape
Rough / Uncut octahedral or irregular crystal form
Overall Assessment
This is a natural, unpolished rough diamond crystal embedded in or showing matrix characteristics. It displays typical natural rough morphology with visible surface textures and internal inclusions. Its ultimate value and grade depend heavily on professional diamond planning, sawing, and cutting to maximize polished yield.
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low in rough state; will increase significantly upon proper cutting and polishing
Fire
Minimal dispersion in rough state due to unpolished surfaces
Scintillation
Limited flash effect from natural crystal faces; requires faceting for optimal light performance
Proportions
Natural rough proportions; requires professional planning for cutting
Symmetry
Natural crystal symmetry (distorted octahedral/dodecahedral growth forms)
Polish
Natural crystal faces (trigons and striations visible)
Fluorescence
Cannot be determined accurately from photograph alone (typically None to Faint in natural rough)
Inclusions
Feathers, clouds, pinpoint inclusions, and dark mineral spots visible within the rough matrix
Blemishes
Natural surface features, etch channels, and rough skin characteristic of unpolished crystals
Origin
Natural alluvial or primary kimberlite/lamproite deposit origin
Treatment Detection
No visible treatments detected; appears entirely untreated and natural
Estimated Value
Varies significantly based on cutting yield, estimated between $300 to $1,500 USD in rough form
Certification Estimate
GIA or IGI (would require professional submission for formal grading report after cutting)
Investment Potential
Moderate to low in rough form unless exceptional clarity is revealed upon sawing
Similar Diamonds
Standard run-of-mine industrial or lower-gem-quality natural rough diamond crystals
Setting Suggestions
Can be set raw in organic, rustic-style jewelry (e.g., in yellow gold or platinum prong/bezel settings) or cut into a modern brilliant shape
Care & Maintenance
Store separately from other gemstones to prevent scratching; clean with warm soapy water and a soft brush
Interesting Facts
Rough diamonds straight from the earth often show natural triangular growth markings called trigons on their faces
