Rough crystal / Irregular slab
Overall Assessment
This is an interesting, natural rough diamond crystal featuring visible inclusions and raw cleavage surfaces. While unsuitable for standard high-jewelry facet cutting without significant weight loss, it makes a fascinating specimen for mineral collectors or custom organic jewelry designs.
Cut Quality
Not applicable (Rough stone, unpolished)
Brilliance
Low due to rough surface and internal inclusions
Fire
Minimal due to lack of standard facet proportions
Scintillation
Poor to none in current rough state
Proportions
Not applicable to rough crystals
Symmetry
Natural crystal symmetry, highly irregular
Polish
Raw, unpolished crystal faces and cleavage planes
Fluorescence
Unknown without UV testing (Likely none to faint blue)
Inclusions
Heavy internal feather fractures, carbon spots, and dark mineral inclusions visible throughout
Blemishes
Surface naturals, rough edges, chips, and striations along crystal growth lines
Origin
Likely alluvial deposit origin (riverbed or marine) given surface weathering
Treatment Detection
No obvious signs of artificial treatments; appears completely untreated and natural
Estimated Value
Low commercial value due to heavy inclusions and rough state (approx. $300 - $800 as a specimen or for industrial use, higher if cut yields high-clarity smaller stones)
Certification Estimate
GIA or EGL (would require comprehensive laboratory testing to confirm natural origin and weight)
Investment Potential
Low as a polished gem investment, moderate as a unique raw mineral specimen
Similar Diamonds
Industrial grade rough diamond crystals or raw specimen stones sold to collectors
Setting Suggestions
Wire-wrapped pendant setting to preserve the raw, organic aesthetic of the uncut crystal
Care & Maintenance
Handle with care to prevent chipping along cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural octahedral or irregular crystal shapes formed deep within the Earth's mantle over billions of years before being brought to the surface by kimberlite pipes.
