Likely Non-Diamond (Potential Synthetic or Glass)
Likely Non-Diamond (Potential Synthetic or Glass) · Rough / Irregular Uncut
Uncut / Rough Cut
Carat
Estimated 2.0 - 5.0 carats based on macro scale
Color
Colorless / D-F equivalent
Clarity
Included (I1-I3 equivalent)
Shape
Rough / Irregular Uncut
Overall Assessment
The specimen lacks the characteristic crystal habit and cleavage planes of a natural diamond rough. It is highly likely to be a fragment of synthetic material or glass based on the curvilinear fracture lines and surface texture.
Cut Quality
Uncut / Rough
Brilliance
Low; surface transparency is high but lack of facets limits light return
Fire
Minimal visible dispersion in current state
Scintillation
None
Proportions
Natural irregular formation
Symmetry
N/A (Rough state)
Polish
N/A (Visual texture shows conchoidal fracturing)
Fluorescence
Indeterminate from image
Inclusions
Heavy internal graining, possible carbon spots, and internal stress fractures
Blemishes
Deep surface pitting and uneven conchoidal ridges
Origin
Indeterminate; secondary surface textures suggest river-worn glass or synthetic crystal fragment
Treatment Detection
Surface shows signs of mechanical abrasion
Estimated Value
Minimal specimen value ($10-$50) unless confirmed as high-quality diamond rough
Certification Estimate
Unlikely to be certified by GIA/AGS as a gemstone; requires basic mineral identification
Investment Potential
Low; appears to be industrial or non-gem grade material
Similar Diamonds
Low-grade industrial diamond rough or rough quartz/glass
Setting Suggestions
Not recommended for jewelry setting in current state; suitable for specimen collection
Care & Maintenance
Avoid impact; clean with soft brush and warm soapy water
Interesting Facts
The conchoidal (shell-like) fracture patterns shown are very characteristic of silica-based materials like glass or quartz, rather than the octahedral cleavage typically seen in diamonds.
