Not a diamond; appears to be raw quartz, glass, or similar crystalline silicate mineral specimen.
Not a diamond; appears to be raw quartz, glass, or similar crystalline silicate mineral specimen. · Rough / Raw irregular crystal fragment
Uncut / Rough Cut

Carat
Cannot be precisely determined visually without density testing, but roughly estimated at 15-25 carats based on size relative to human hand.
Color
Colorless with inclusions and surface staining
Clarity
Included / I3 equivalent for gem grading standards due to numerous internal fractures and inclusions
Shape
Rough / Raw irregular crystal fragment
Overall Assessment
The specimen shown in the image is a raw, unpolished mineral fragment (likely quartz or glass) rather than a diamond. It displays conchoidal fracture patterns and surface inclusions typical of raw crystalline minerals found in nature.
Cut Quality
Uncut / Rough
Brilliance
Low to moderate due to internal fractures and lack of precise facet geometry
Fire
Minimal dispersion, typical of quartz rather than diamond or moissanite
Scintillation
Poor due to lack of standard faceted pavilion and crown angles
Proportions
Not applicable to raw mineral specimens
Symmetry
Asymmetrical due to natural raw formation
Polish
Unpolished raw mineral surface with natural conchoidal fractures
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal fracturing, cloudiness, and particulate matter
Blemishes
Surface pitting, chips, and adhering matrix material
Origin
Natural terrestrial mineral specimen, likely found in a pegmatite pocket, hydrothermal vein, or alluvial deposit.
Treatment Detection
No obvious signs of human treatment; appears entirely natural.
Estimated Value
Minimal monetary value as a gem; valued primarily as a mineral specimen or decorative rough crystal rock, typically under $20 USD.
Certification Estimate
Not eligible for standard diamond grading laboratories (GIA, AGS, IGI); would require a mineralogical certificate from an institute like GIA Colored Stone or a local gemological lab.
Investment Potential
No financial investment potential as a gemstone; purely decorative or educational.
Similar Diamonds
None, as this is not a diamond.
Setting Suggestions
Wire-wrapped setting in sterling silver or copper for raw crystal jewelry.
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh acids or sudden thermal shocks.
Interesting Facts
Raw quartz and similar silicate crystals are often mistaken for rough diamonds by novices due to their glassy luster and transparency.
