Indeterminate - Likely non-gemstone material (Glass, Slag, or Quatz)
Indeterminate - Likely non-gemstone material (Glass, Slag, or Quatz) · Rough / Uncut (Amorphous shard)
Uncut / Raw Cut
Carat
Estimated 10-25 carats based on human fingers in background
Color
Near-colorless with industrial/grey undertones
Clarity
I3 or lower (Heavily included/Opaque in areas)
Shape
Rough / Uncut (Amorphous shard)
Overall Assessment
The specimen appears to be a shard of non-gem grade material, likely glass, quartz, or industrial byproduct. It lacks the crystal structure, luster, and refractive properties of a high-quality natural diamond.
Cut Quality
Uncut / Raw
Brilliance
Low (Surface reflections only, no internal refraction)
Fire
None visible
Scintillation
Low to None
Proportions
N/A
Symmetry
N/A (Asymmetrical shard)
Polish
Natural/Rough Surface
Fluorescence
Cannot be determined from image
Inclusions
Extensive internal fracturing, heavy cloudiness, and possible fluid inclusions
Blemishes
Conchoidal fractures, sharp edges, and surface pitting
Origin
Likely secondary source material, industrial byproduct, or riverbed quartz
Treatment Detection
No apparent treatments; appears to be raw waste material
Estimated Value
Negligible market value as a gemstone
Certification Estimate
Likely ineligible for standard diamond grading (GIA/IGI) due to lack of gem quality
Investment Potential
None
Similar Diamonds
Uncut industrial bort or decorative glass cullet
Setting Suggestions
Not suitable for jewelry setting without significant lapidary work
Care & Maintenance
Handle with care as conchoidal fractures can be sharp; keep away from household cleaners
Interesting Facts
The way this material breaks (conchoidal fracture) is more characteristic of glass or quartz than the octahedral cleavage of a natural diamond.
