Likely Moissanite or Synthetic Simulate
Likely Moissanite or Synthetic Simulate · Irregular / Rough Crystal (Fragmented)
Poor (Uncut/Rough state) Cut
Carat
Estimated 2.5 - 4.0 carats based on visual scale
Color
Colorless (D-F range equivalent)
Clarity
SI1 - I1 (due to visible surface fractures and internal graining)
Shape
Irregular / Rough Crystal (Fragmented)
Overall Assessment
This appears to be a high-dispersion synthetic rough crystal, likely Moissanite, rather than a natural rough diamond, given the extreme fire and crystal habit.
Cut Quality
Poor (Uncut/Rough state)
Brilliance
Moderate; hindered by rough surface texture
Fire
Very High (suggestive of Moissanite’s high refractive index)
Scintillation
Low due to lack of faceted surfaces
Proportions
Variable; asymmetric crystal habit
Symmetry
N/A (Rough crystal fragment)
Polish
Poor (Unpolished original surface)
Fluorescence
Indeterminate; internal rainbows suggest high dispersion rather than fluorescence
Inclusions
Feathers, internal fractures, and possible carbon spots
Blemishes
Nick, pits, and rough skin on external surfaces
Origin
Likely lab-grown material (Moissanite) or synthetic sapphire
Treatment Detection
None visible; appears to be raw synthetic crystal
Estimated Value
$50 - $400 USD (highly dependent on verified material)
Certification Estimate
Gemological Appraisal (GGL or local lab); unlikely for GIA without faceting
Investment Potential
Low; rough synthetic materials do not typically appreciate
Similar Diamonds
Rough white diamonds from Arkansas or Siberian lab-grown rough
Setting Suggestions
Wire wrap, custom 'rough' claw setting, or rough diamond pendant style
Care & Maintenance
Avoid ultrasonic cleaners if fractures are deep; clean with mild soap and soft brush
Interesting Facts
The rainbow dispersion at the top edge is characteristic of 'doubly refractive' materials like Moissanite.
