Natural rough stone (likely quartz or glass given the conchoidal fracture and surface texturing, requiring professional testing to rule out diamond)
Natural rough stone (likely quartz or glass given the conchoidal fracture and surface texturing, requiring professional testing to rule out diamond) · Uncut raw crystal fragment / irregular rough form
Not applicable (Rough, unpolished raw specimen) Cut

Carat
Estimated 15-25 carats based on visual scale in hand
Color
Colorless / Clear with faint surface reflections
Clarity
Included / Imperfect due to internal irregularities and structural lines
Shape
Uncut raw crystal fragment / irregular rough form
Overall Assessment
An interesting transparent raw mineral fragment that requires specialized gemological testing (such as thermal conductivity and refractive index testing) to confirm its exact mineral identity
Cut Quality
Not applicable (Rough, unpolished raw specimen)
Brilliance
Low to moderate vitreous luster typical of raw unfaceted minerals
Fire
Minimal dispersion due to lack of precision-cut facets
Scintillation
Limited flash due to irregular raw surfaces
Proportions
Non-standard raw stone measurements without traditional table or depth
Symmetry
Asymmetrical raw crystal formation
Polish
Unpolished natural raw surface with conchoidal fracture patterns
Fluorescence
Unable to determine without UV testing (Likely none to faint)
Inclusions
Internal micro-fractures, strain lines, and structural irregularities visible
Blemishes
Natural surface pitting, uneven texture, and conchoidal fracture ripples
Origin
Alluvial deposit or rough mineral matrix specimen
Treatment Detection
No obvious signs of artificial enhancement; appears as found in nature
Estimated Value
Nominal value depending on definitive mineral composition; low if glass or common quartz, higher if identified as a rare gem rough
Certification Estimate
Gemological testing required at a lab like GIA or GRS for exact mineral identification
Investment Potential
Speculative; dependent entirely on certified gemological classification
Similar Diamonds
Comparable to large, low-grade industrial diamond rough or clear quartz crystal fragments
Setting Suggestions
Wire-wrapped organic pendant setting or custom prongs to preserve its raw aesthetic
Care & Maintenance
Store separately in a soft pouch to prevent scratching other softer gemstones or collecting debris in fractures
Interesting Facts
Raw mineral specimens display natural growth lines and conchoidal fractures that reveal how the material broke or grew under geological pressure
