Not a diamond; this specimen appears to be green glass or a green mineral like tourmaline/emerald rough with conchoidal fracture, but visually strongly resembles industrial green glass.

Not Applicable (Uncut Raw Specimen) Cut
Carat
Estimated 3.5 - 5.0 carats equivalent weight (dependent on specific gravity)
Color
Fancy Deep Green
Clarity
Included (SI2 equivalent due to internal flow lines and bubbles)
Shape
Rough / Raw Uncut Fragment
Overall Assessment
This specimen is visually identified as green glass or a non-diamond mineral rough rather than a genuine green diamond. Professional gemological testing (refractive index, hardness test) is strongly advised before making any financial valuation.
Cut Quality
Not Applicable (Uncut Raw Specimen)
Brilliance
Vitreous glass-like luster, moderate white light return
Fire
Very low dispersion compared to diamond
Scintillation
Limited due to lack of standard facet arrangement
Proportions
Irregular raw crystal/fragment proportions
Symmetry
Asymmetrical raw fragment
Polish
Raw / Unpolished conchoidal surfaces with vitreous luster
Fluorescence
Unknown / Not tested under UV
Inclusions
Conchoidal fracture ripples, flow lines, and potential gas bubbles typical of glass
Blemishes
Surface chips and natural irregularities from fracturing
Origin
Synthetic / Man-made glass or natural rough mineral specimen
Treatment Detection
Colored glass or potentially irradiated/coated material
Estimated Value
$5 - $20 USD (as a decorative mineral specimen or piece of glass)
Certification Estimate
Not applicable for grading labs like GIA as a diamond; would require GIA Colored Stone report or gemological testing to confirm identity
Investment Potential
Negligible; has no monetary or gem-grade investment value
Similar Diamonds
None, as this is not a diamond
Setting Suggestions
Wire-wrapped pendant setting using sterling silver or copper
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and sudden temperature changes
Interesting Facts
Green-colored rough materials are frequently mistaken for precious emeralds or green diamonds by novices, though conchoidal fracture lines often give away glass
