Overall Assessment
This specimen is a vibrant green rough crystal rather than a diamond. It possesses natural aesthetic charm as a mineral specimen, requiring professional gemological testing to determine its exact species (e.g., emerald, tourmaline, or green glass).
Cut Quality
Not applicable (Rough uncut crystal)
Brilliance
Low due to lack of standard facet angles and rough surface polish
Fire
Low, characteristic of emerald or tourmaline rather than diamond
Scintillation
Minimal, limited to surface light reflection on natural crystal faces
Proportions
Irregular raw crystal dimensions
Symmetry
Natural asymmetric crystal growth
Polish
None (Raw crystal surface with natural striations)
Fluorescence
Indeterminate without UV testing
Inclusions
Heavy natural inclusions, internal fractures, and crystal growth tubes typical of beryl/tourmaline
Blemishes
Surface pits, natural striations, and rough edges
Origin
Natural rough mineral, potential origin in Colombia, Zambia, or Brazil if confirmed as emerald
Treatment Detection
Visual inspection suggests untreated rough, though clarity enhancement (oil/resin) is common in cut emeralds
Estimated Value
Depends heavily on exact mineral species, but raw specimens of this type vary from $50 to $300 for decorative or specimen mineral use
Certification Estimate
GIA or Gübelin (Gemological Report for colored stones rather than diamond grading)
Investment Potential
Low for general investment; primarily collected as a mineral specimen rather than a high-value gemstone
Similar Diamonds
None, as this is a colored gemstone rough and not a diamond
Setting Suggestions
Custom wire-wrapped setting or prong setting designed specifically to secure rough organic mineral specimens
Care & Maintenance
Avoid ultrasonic cleaners, harsh chemicals, and sudden temperature changes, especially if it is an emerald
