Quartz crystal or glass imitation (not a true diamond based on rough habit and conchoidal fractures, likely quartz or herkimer diamond rough)
Quartz crystal or glass imitation (not a true diamond based on rough habit and conchoidal fractures, likely quartz or herkimer diamond rough) · Raw crystal / Irregular rough elongation
Uncut / Raw crystal form (Not applicable) Cut
Carat
Approx. 2.5 - 4.0 carats equivalent weight (dependent on specific gravity)
Color
Colorless / Transparent
Clarity
Included (contains internal fractures and inclusions)
Shape
Raw crystal / Irregular rough elongation
Overall Assessment
The specimen displayed is a raw, transparent crystal with visible striations and internal fractures, highly characteristic of quartz or a mineral crystal rather than gem-quality diamond rough.
Cut Quality
Uncut / Raw crystal form (Not applicable)
Brilliance
Vitreous luster, moderate white light reflection
Fire
Low dispersion (typical of quartz/glass rather than diamond)
Scintillation
Limited due to lack of standard diamond facets
Proportions
Natural elongated crystal habit with striated faces
Symmetry
Natural crystal growth symmetry
Polish
Unpolished natural crystal faces
Fluorescence
Cannot be determined without UV testing (Likely None to Faint)
Inclusions
Feathers, fractures, and internal inclusions visible
Blemishes
Natural surface irregularities, striations, and edge chips
Origin
Natural mineral rough / geological specimen
Treatment Detection
No obvious treatments detected
Estimated Value
Nominal value ($10 - $50 as mineral specimen)
Certification Estimate
Not applicable for standard diamond grading labs (GIA/AGS would issue report identifying as quartz or simulant if submitted)
Investment Potential
Low (decorative or specimen value only)
Similar Diamonds
None, this is a raw mineral crystal rather than a diamond
Setting Suggestions
Wire-wrapped pendant setting or kept as a raw mineral specimen
Care & Maintenance
Standard cleaning with warm soapy water and a soft brush; avoid harsh impacts due to cleavage/fracture planes
Interesting Facts
Raw quartz and mineral crystals are frequently mistaken for rough diamonds by amateurs due to their transparency and crystal points
