Not a diamond; appears to be a natural quartz crystal fragment or mineral glass with distinctive conchoidal fracture patterns.
Not a diamond; appears to be a natural quartz crystal fragment or mineral glass with distinctive conchoidal fracture patterns. · Irregular raw crystal fragment / elongated shard
Uncut / Raw natural crystal form Cut

Carat
Not applicable as this is not a gemstone-quality diamond; weight would need physical scale measurement.
Color
Colorless / Transparent
Clarity
Not applicable to non-diamond minerals; visible striations and internal growth lines present.
Shape
Irregular raw crystal fragment / elongated shard
Overall Assessment
The specimen shown in the image is an uncut, elongated mineral crystal or glass shard rather than a diamond, characterized by visible conchoidal fractures and natural striations.
Cut Quality
Uncut / Raw natural crystal form
Brilliance
Low to moderate vitreous luster typical of raw quartz or glass
Fire
Very low dispersion compared to diamond
Scintillation
Minimal, limited to light reflection off flat fracture planes
Proportions
Not applicable to raw mineral formations
Symmetry
Asymmetrical raw mineral specimen
Polish
Raw, unpolished surface showing natural cleavage and fracture planes
Fluorescence
Cannot be determined without UV light testing
Inclusions
Natural growth lines, parallel striations, and minor mineral specks
Blemishes
Surface chips, natural irregularities, and fracture lines along the edges
Origin
Natural geological mineral formation
Treatment Detection
No signs of artificial treatment; appears entirely natural
Estimated Value
Nominal mineral specimen value (very low)
Certification Estimate
Not certifiable by major diamond grading laboratories (GIA, IGI) as it is not a diamond.
Investment Potential
None; educational or mineral collecting value only.
Similar Diamonds
None, as this specimen is chemically and structurally distinct from diamond.
Setting Suggestions
Not recommended for jewelry settings due to softness and irregular shape; suitable as a mineral specimen display.
Care & Maintenance
Standard mineral care; avoid hard impacts to prevent chipping along cleavage planes.
Interesting Facts
Displays clear conchoidal fracture lines and growth striations common in quartz and certain glasses.
