Not a diamond; this is a rough green gemstone, likely Peridot or rough Green Tourmaline, displaying natural crystalline structure and inclusions.
Not a diamond; this is a rough green gemstone, likely Peridot or rough Green Tourmaline, displaying natural crystalline structure and inclusions. · Rough uncut crystal, irregular pebble form with natural faces and fractures.
Not applicable (uncut rough material). Cut
Carat
Estimated around 3.50 to 5.00 carats based on visual scale against fingers.
Color
Vivid yellowish-green to bright green (Fancy Intense Green if evaluated as colored gemstone).
Clarity
Included (I1/I2 equivalent), showing internal fractures, dark mineral inclusions, and cloudiness.
Shape
Rough uncut crystal, irregular pebble form with natural faces and fractures.
Overall Assessment
An interesting, vibrant green rough crystal specimen held between fingers, showcasing natural internal features and lively color, though it possesses no diamond characteristics.
Cut Quality
Not applicable (uncut rough material).
Brilliance
Moderate to low due to opacity, internal fracturing, and lack of precision faceting.
Fire
Low dispersion observed in the rough state, obscured by body color and fractures.
Scintillation
Minimal sparkle, flashes limited to natural cleavage planes and small polished-looking facets.
Proportions
Not applicable to rough crystals; irregular depth and dimensions.
Symmetry
Natural asymmetrical crystal formation.
Polish
Raw, unpolished natural crystal surface with some surface etching or matrix remnants.
Fluorescence
Cannot be determined without UV testing, likely inert.
Inclusions
Significant internal fractures, dark spot inclusions, and structural feathering typical of raw pegmatite or mantle-derived minerals.
Blemishes
Natural surface pitting, rough patches, and minor adhering matrix material.
Origin
Likely alluvial deposit or volcanic matrix origin, common for peridot or tourmaline.
Treatment Detection
No obvious signs of artificial treatment; appears completely untreated and natural rough.
Estimated Value
Modest value as a mineral specimen or rough lapidary material, approximately $50 - $200 depending on exact mineral species.
Certification Estimate
Gemological testing laboratory (such as GIA or local institute) would issue a colored gemstone identification report rather than a diamond grading report.
Investment Potential
Low investment potential; primarily of interest to mineral collectors or lapidary artists.
Similar Diamonds
None, as this is a colored silicate mineral rather than diamond (carbon allotrope).
Setting Suggestions
Wire-wrapped pendant setting, custom organic bezel setting, or kept as a raw mineral specimen.
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and sudden temperature changes due to internal fractures.
Interesting Facts
Green rough stones like peridot originate from deep within the Earth's mantle or are occasionally found in pallasite meteorites.
