Overall Assessment
An interesting, tactile specimen of a natural rough diamond crystal displaying characteristic growth lines and surface features, ideal either as a collector mineral specimen or for custom raw-diamond jewelry.
Cut Quality
Not applicable (Rough, un-faceted crystal)
Brilliance
Limited due to rough surface and natural crystal texture
Fire
Present in localized transparent windows, but subdued by rough exterior
Scintillation
Minimal to none due to lack of standard facet arrangement
Proportions
N/A for rough crystal
Symmetry
Natural crystal symmetry, distorted octahedron/blocky form

Estimated Value
$400 - $800 depending on cutter yield and final cut grade potential
Certification Estimate
