Overall Assessment
An intriguing, natural rough diamond crystal displaying authentic geological characteristics, ideal for a bespoke or raw-diamond jewelry designer looking for a unique, organic centerpiece
Cut Quality
Not applicable (Rough crystal, un-faceted)
Brilliance
Low brilliance due to rough, unpolished surfaces scattering light externally
Fire

Limited, reflecting light off natural crystal faces rather than precision facets
Proportions
N/A for raw stones, exhibits natural distorted octahedral morphology
Symmetry
Asymmetrical raw crystal form typical of unpolished natural diamond rough
Polish
