Natural rough diamond crystal piece
Natural rough diamond crystal piece · Uncut rough, fragment or cleavage piece with irregular elongated form
Not applicable as this is an unpolished, rough crystal fragment Cut
Carat
Estimated around 1.5 to 2.5 carats based on visual scale in hand
Color
Near-colorless to faint brown tint (approx. G-I range)
Clarity
Included (I1-I2 range due to numerous visible internal feathers and surface fractures)
Shape
Uncut rough, fragment or cleavage piece with irregular elongated form
Overall Assessment
An interesting raw diamond fragment displaying natural geological characteristics, ideal for mineral collectors or custom organic jewelry designs rather than traditional high-end faceted settings.
Cut Quality
Not applicable as this is an unpolished, rough crystal fragment
Brilliance
Low due to lack of standard faceted proportions and surface texture
Fire
Minimal dispersion visible due to rough, unpolished state
Scintillation
Poor to fair; limited reflective facets present naturally
Proportions
Non-standard; raw elongated cleavage fragment with natural depth and uneven contours
Symmetry
Natural irregular symmetry characteristic of rough cleavage fragments
Polish
Natural crystal faces and cleavage planes, unpolished
Fluorescence
Indeterminate without UV testing (likely none to moderate blue)
Inclusions
Multiple dark carbon spots, feathers, internal stress cracks, and cloud-like inclusions
Blemishes
Natural surface etch channels, trigons, rough natural skin, and cleavage steps
Origin
Likely alluvial or primary kimberlite source (Africa, Canada, or Russia)
Treatment Detection
No treatments detected; appears completely untreated and natural
Estimated Value
Modest collector or industrial/specimen value, highly dependent on cutting potential
Certification Estimate
GIA would issue a Diamond Rough Report or identification report if submitted
Investment Potential
Low as a finished gemstone, but moderate as a collector's mineral specimen
Similar Diamonds
Typical run-of-mine industrial or lower-clarity jewelry grade rough fragments
Setting Suggestions
Wire-wrapped rough pendant or custom bezel setting designed to showcase raw crystal aesthetics
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their geological history, showing natural growth features like striations and trigons formed deep within the Earth's mantle.
