Rough Quartz / Glass Simulator (Not a genuine diamond)
Rough Quartz / Glass Simulator (Not a genuine diamond) · Irregular raw crystal / Polished nugget form
Poor / Unfaceted raw or partially worked nodule Cut
Carat
Excess of 50 carats equivalent by size, though non-diamond material
Color
Colorless with heavy inclusion staining
Clarity
Included / I3 equivalent due to massive fractures and foreign material inclusions
Shape
Irregular raw crystal / Polished nugget form
Overall Assessment
The specimen shown in the image lacks the characteristic octahedral crystal habit, extreme hardness, and optical properties of a true diamond, pointing instead toward a rough quartz crystal or glass simulants with significant internal fractures.
Cut Quality
Poor / Unfaceted raw or partially worked nodule
Brilliance
Very low due to lack of standard facet angles and heavy internal flaws
Fire
Minimal to none
Scintillation
Absent
Proportions
Not applicable to standard faceted diamonds
Symmetry
Asymmetrical raw formation
Polish
Poor to fair, showing natural or roughly tumbled surfaces
Fluorescence
None observed
Inclusions
Heavy internal fractures, feathering, and metallic/organic staining
Blemishes
Surface pitting, chips, and deep abrasions
Origin
Natural quartz or synthetic glass simulants
Treatment Detection
Possible fracture healing or staining simulation
Estimated Value
Nominal / Mineral specimen value only (under $50)
Certification Estimate
Not certifiable as diamond by major labs (GIA/AGS); would be identified as quartz or glass
Investment Potential
None as a gemstone or diamond asset
Similar Diamonds
None, as this is visually identified as quartz or glass rather than diamond
Setting Suggestions
Wire-wrapped raw mineral setting if kept as a specimen
Care & Maintenance
Standard cleaning with warm soapy water and a soft brush; avoid harsh impacts
Interesting Facts
Rough quartz crystals and glass simulants are frequently mistaken for rough diamonds by novices due to their vitreous luster and transparency.
