Non-Diamond / Likely Glass or Quartz
Non-Diamond / Likely Glass or Quartz · Natural/Rough macle with conchoidal fracture
Uncut / Raw Cut
Carat
Estimated 3-5 carats
Color
Colorless to Near-Colorless
Clarity
Included (I-grade equivalent)
Shape
Natural/Rough macle with conchoidal fracture
Overall Assessment
The specimen shown lacks the optical properties and physical cleavage patterns of a diamond. The visible fracture patterns are characteristic of glass or silicate minerals like quartz.
Cut Quality
Uncut / Raw
Brilliance
Low; lack of internal reflection
Fire
Low to None
Scintillation
Poor; restricted by lack of facets
Proportions
Irregular / Unfaceted
Symmetry
Asymmetrical / Natural
Polish
Natural / Smooth surface on primary face
Fluorescence
Non-fluorescent based on image
Inclusions
Prominent internal fractures and red mineral specks
Blemishes
Chipped edges and conchoidal fracture scars
Origin
Likely synthetic glass or common crystalline quartz
Treatment Detection
No visible treatments, appears as raw material
Estimated Value
$10 - $50 (assuming glass or common quartz)
Certification Estimate
Unlikely to be certified as a diamond by GIA/AGS
Investment Potential
Zero for investment purposes
Similar Diamonds
None; characteristics do not match diamond
Setting Suggestions
Not suitable for traditional jewelry setting in current state
Care & Maintenance
Avoid impact; high risk of further fracturing
Interesting Facts
The presence of a conchoidal (shell-like) fracture is a diagnostic indicator that this is not a diamond, as diamonds exhibit octahedral cleavage.
