Natural rough crystal / Uncut diamond matrix
Natural rough crystal / Uncut diamond matrix · Rough / Octahedral-like irregular crystal form
Not applicable (Rough, unpolished crystal specimen) Cut
Carat
Estimated 3.5 to 5.0 carats based on rough dimensions
Color
Near-colorless to faint yellow/brown tint (Typical for rough diamond matrix)
Clarity
Included (I1-I3 scale equivalent for rough stone with visible cloudiness and inclusions)
Shape
Rough / Octahedral-like irregular crystal form
Overall Assessment
This is a fascinating specimen of an uncut, natural rough diamond in its matrix, holding potential for custom lapidary work or as a prized mineral collection piece
Cut Quality
Not applicable (Rough, unpolished crystal specimen)
Brilliance
Low in rough form; will improve dramatically upon professional cutting and polishing
Fire
Subdued in rough form due to frosted and unpolished surface facets
Scintillation
Minimal play of light currently; limited to reflective surface planes on the rough crystal
Proportions
Natural proportions dictated by crystallization rather than facet angles
Symmetry
Natural crystal growth symmetry, asymmetrical rough form
Polish
Raw, unpolished natural crystal faces (trigons potentially visible under magnification)
Fluorescence
Indeterminate from visual assessment alone, but typical natural rough often shows blue or yellow under UV
Inclusions
Heavy internal clouding, feathers, and potential pinpoint inclusions visible throughout the raw crystal matrix
Blemishes
Natural surface textures, pitting, and irregular growth lines typical of uncut minerals
Origin
Likely alluvial or primary kimberlite pipe origin (Africa, Canada, or Russia)
Treatment Detection
No signs of artificial treatment; completely untreated natural rough crystal specimen
Estimated Value
Variable based on yield potential post-cut; rough industrial or lower gem-grade value estimated at $500 - $1,500
Certification Estimate
GIA or similar major laboratory would grade this as a natural rough diamond study or spec
Investment Potential
Collectible mineral value rather than standard polished diamond investment; holds moderate curiosity value
Similar Diamonds
Comparable natural rough diamond specimens and unassorted run-of-mine parcel stones
Setting Suggestions
Best preserved as a raw mineral specimen, or cut into a custom rustic rose-cut or brilliant-cut diamond
Care & Maintenance
Handle with care to prevent chipping along natural cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds exhibit natural crystal shapes such as octahedrons and dodecahedrons formed deep within the Earth's mantle
