Carat

Not applicable (specimen is measured in grams/carats as rough mineral, visually substantial but un-gem-grade)

Color

Light pale green to translucent white (fancy color description for mineral specimen, not applicable to D-Z scale)

Clarity

Included / Included 3 (substantial internal fractures, cleavage planes, and mineral inclusions typical of raw matrix specimens)

Shape

Rough crystal form (uncut, raw mineral specimen with natural tabular or prismatic habits)

Overall Assessment

The uploaded image does not contain a diamond. It shows a natural, rough mineral crystal specimen on matrix, likely belonging to the silicate group (such as apophyllite or prehnite). It is of interest to mineral collectors rather than the gem diamond market.

Cut Quality

Not applicable (uncut raw crystal matrix)

Brilliance

Vitreous to pearly luster on cleavage planes, differing sharply from adamantine diamond brilliance

Fire

Low dispersion, characteristic of silicate minerals rather than high-dispersion diamond

Scintillation

Limited to flashes from natural crystal faces and cleavage planes

Proportions

Irregular natural crystal habit; depth and table percentages do not apply

Symmetry

Natural crystal symmetry (monoclinic or tetragonal crystal system characteristics)

Polish

Raw, unpolished natural crystal faces and cleavage planes

Fluorescence

Unknown / Not tested under UV light

Inclusions

Heavy internal fractures, veils, and trapped mineral particulate inclusions characteristic of pegmatite or hydrothermal vein minerals

Blemishes

Natural growth steps, surface etching, and rough edges on matrix

Origin

Natural mineral specimen, likely sourced from hydrothermal vein deposits (e.g., India, Brazil, or South Africa depending on exact mineral species)

Treatment Detection

No signs of artificial enhancement; appears to be completely natural as-mined mineral matrix

Estimated Value

Mineral specimen market value (dependent on aesthetics and locality), ranging from $20 to $150 USD for collector display

Certification Estimate

Gemological laboratories (like GIA or IGI) do not certify raw mineral matrix specimens; mineralogical identification requires XRD or Raman spectroscopy.

Investment Potential

Low investment liquidity; primarily valued as a decorative or educational mineral specimen for collectors

Similar Diamonds

None (this is not a diamond, comparable only to other collector mineral specimens such as zeolites or prehnite)

Setting Suggestions

Display as a raw mineral specimen on a custom acrylic stand rather than traditional jewelry setting

Care & Maintenance

Handle with care to avoid chipping soft cleavage planes; avoid harsh chemical cleaning, ultrasonic cleaners, and prolonged exposure to direct sunlight

Interesting Facts

The specimen exhibits classic stepped growth features and natural tabular crystallization common in hydrothermal silicate minerals.
