Rough natural diamond crystal (or industrial-grade diamond crystal/bort specimen)
Rough natural diamond crystal (or industrial-grade diamond crystal/bort specimen) · Uncut, irregular natural crystal form with trigons and growth lines
Not applicable (Rough, un-faceted stone) Cut
Carat
Estimated 3.5 to 5.0 carats based on visual size relative to fingertips
Color
Near-colorless to light brown tint (approximate G-I range if cut)
Clarity
Included / I1-I3 range due to visible internal cloudiness and surface features
Shape
Uncut, irregular natural crystal form with trigons and growth lines
Overall Assessment
An interesting raw, uncut diamond specimen displaying natural crystallization features, best suited for mineral collectors or custom organic jewelry design rather than standard faceted gemstone markets.
Cut Quality
Not applicable (Rough, un-faceted stone)
Brilliance
Low in rough form; limited to surface reflection on natural crystal faces
Fire
Minimal dispersion visible in current uncut state
Scintillation
Absent in rough form due to lack of facets
Proportions
Natural uncut proportions; no standard table, depth, or angles apply
Symmetry
Natural asymmetrical crystal growth
Polish
Natural rough crystal faces showing striations and trigons
Fluorescence
Unable to determine without UV testing (likely none to medium blue)
Inclusions
Dense internal clouds, micro-fractures, and mineral inclusions typical of rough stones
Blemishes
Natural surface pitting, rough skin, striations, and resorption features
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Industrial to lower commercial value as a mineral specimen; valuation depends strictly on weight and intended use (specimen vs. cutting rough)
Certification Estimate
GIA or local gemological laboratories for authenticity report rather than full grading
Investment Potential
Low investment potential for standard commercial rough; mainly valued as a geological specimen or unique raw jewelry piece
Similar Diamonds
Comparable to standard run-of-mine industrial or lower-quality gem rough diamonds
Setting Suggestions
Raw uncut diamond jewelry setting, such as a wire-wrap, bezel, or organic prong setting in yellow or white gold
Care & Maintenance
Clean with warm soapy water and a soft brush; protect from hard impacts which could exploit natural cleavage planes
Interesting Facts
Displays natural growth markings such as striations and surface texture common in un-cut diamond crystallization
