Natural rough mineral (Likely quartz or calcite rather than gem-quality diamond)
Natural rough mineral (Likely quartz or calcite rather than gem-quality diamond) · Rough crystal / Irregular unpolished chunk
Not Applicable (Uncut rough specimen) Cut
Carat
Estimated 15-25 carats equivalent based on overall physical volume
Color
Milky white to translucent with dark mineral inclusions
Clarity
I3 (Heavy inclusions and opaque zones)
Shape
Rough crystal / Irregular unpolished chunk
Overall Assessment
This specimen is a raw, opaque white mineral chunk rather than a diamond. It lacks the crystal habit, adamantine luster, and hardness characteristic of rough diamonds. It is best appreciated as a natural geological specimen.
Cut Quality
Not Applicable (Uncut rough specimen)
Brilliance
Very low due to opacity and lack of faceting
Fire
Negligible
Scintillation
None due to lack of standard gemstone cuts and polished facets
Proportions
Not Applicable for rough stones
Symmetry
Asymmetrical, natural growth habit
Polish
Raw, unpolished surface
Fluorescence
Cannot be determined without UV light testing
Inclusions
Heavy internal cloudiness, fractures, and distinct dark/black mineral spots visible
Blemishes
Natural surface pitting and rough texture from matrix host rock
Origin
Natural terrestrial mineral deposit
Treatment Detection
No treatments detected; completely natural raw state
Estimated Value
Nominal value (under $10 USD as a raw rock specimen)
Certification Estimate
Not certifiable as a gemstone by major labs (GIA/AGS); purely a mineral specimen
Investment Potential
None as an investment gemstone
Similar Diamonds
None, as this visually resembles rough quartz or quartzite rather than crystalline diamond
Setting Suggestions
Wire-wrapped pendant or raw mineral display piece
Care & Maintenance
Store dry, avoid harsh impacts that could fracture the brittle structure, clean gently with mild soapy water
Interesting Facts
Raw mineral specimens like this are often mistaken for rough diamonds by amateur collectors due to their white, crystalline appearance
