Not a diamond; appears to be raw quartz or glass/slag crystal
Not a diamond; appears to be raw quartz or glass/slag crystal · Rough uncut irregular shard
Not applicable (uncut raw specimen) Cut
Carat
Estimated roughly 15-20 carats based on volume
Color
Colorless / Transparent
Clarity
Included (contains internal striations and fractures)
Shape
Rough uncut irregular shard
Overall Assessment
The specimen shown is an amorphous or crystalline transparent shard, almost certainly quartz or glass rather than a diamond. It exhibits none of the characteristic crystal habits, hardness, or optical properties of diamond.
Cut Quality
Not applicable (uncut raw specimen)
Brilliance
Low to moderate due to lack of standard facet geometry
Fire
Minimal dispersion
Scintillation
Poor, lacks facet patterning
Proportions
Irregular elongated shard
Symmetry
Asymmetrical natural or fractured form
Polish
Raw natural or broken surface, unpolished
Fluorescence
Unknown without UV testing, likely none to faint
Inclusions
Visible internal fractures, striations, and bubbles or mineral pockets
Blemishes
Rough edges, chips, and surface irregularities
Origin
Likely natural mineral specimen (quartz) or anthropogenic glass/slag found outdoors
Treatment Detection
No treatments detected; raw unaltered state
Estimated Value
Nominal, little to no commercial gem value
Certification Estimate
Not eligible for diamond certification laboratories (GIA/AGS); could be analyzed by a general gemological lab as quartz or glass
Investment Potential
None as an investment
Similar Diamonds
None, as this is not diamond material
Setting Suggestions
Wire-wrapped organic pendant or kept as a raw mineral specimen
Care & Maintenance
Standard cleaning with mild soap and water; store carefully to avoid chipping the fragile edges
Interesting Facts
Many rough transparent quartz crystals or pieces of discarded glass are frequently mistaken for raw diamonds by finders in the field
