Rough Quartz Crystal / Slag Glass (Not a Diamond)
Rough Quartz Crystal / Slag Glass (Not a Diamond) · Uncut Raw Mineral Specimen / Conchoidal Fractured Glass
Not Applicable (Uncut natural/industrial material) Cut
Carat
Undetermined due to raw, unpolished, non-gem state
Color
Colorless / Clear with earthy surface contamination
Clarity
Included / Heavily Fractured (Not applicable for gem grading)
Shape
Uncut Raw Mineral Specimen / Conchoidal Fractured Glass
Overall Assessment
This specimen is definitively not a diamond. Visual inspection reveals conchoidal fracture patterns and embedded matrix typical of raw quartz, beryl, or industrial slag rather than crystallographic diamond habits.
Cut Quality
Not Applicable (Uncut natural/industrial material)
Brilliance
Poor due to lack of standard facet alignment and surface dirt
Fire
Negligible dispersion compared to a faceted diamond
Scintillation
None due to absence of precise facet placement
Proportions
Not applicable to raw crystalline aggregates or glass chunks
Symmetry
Asymmetrical raw mineral formation
Polish
Unpolished, rough conchoidal fracture surfaces
Fluorescence
Unknown without UV testing
Inclusions
Massive internal fractures, stress cracks, and trapped sediment/dirt
Blemishes
Deep surface chips, scratches, and textural irregularities
Origin
Terrestrial mineral deposit or industrial byproduct
Treatment Detection
None detected; appears to be raw unprocessed material
Estimated Value
Nominal mineral specimen value (less than $10 USD)
Certification Estimate
Not gradable by major gemological labs (GIA/AGS) as a diamond
Investment Potential
None as an investment gemstone
Similar Diamonds
None (This specimen is not a diamond)
Setting Suggestions
Not suitable for fine jewelry settings in its current form
Care & Maintenance
Clean with mild soap and water to remove surface dirt and debris
Interesting Facts
The prominent curved, rippled surfaces visible are conchoidal fractures typical of quartz or glass rather than the octahedral cleavage planes of a diamond
