N/A (Uncut) Cut
Carat
Estimated 10-20 carats based on size relative to carpet fibers
Color
Translucent greyish-white with hints of blue/lavender
Clarity
Opaque to Translucent (I3 or below if graded as diamond)

Terrestrial mineral (likely common silicate or halide)
Treatment Detection
None apparent; appears to be a raw natural stone
Estimated Value
Minimal (Specimen value only, likely under $5.00)
Certification Estimate
Unlikely to be accepted by GIA/IGI as a gem-quality diamond

None (Decorative or hobbyist value only)
Similar Diamonds
Industrial grade boart (if it were diamond)
Setting Suggestions
Wire wrap or specimen display box
Care & Maintenance
Keep clean with water; avoid dropping as internal fractures suggest fragility
