Natural Fancy Green Diamond (or potentially Green Tourmaline/Tsavorite/Peridot requiring physical testing, assuming a natural green crystal structure)
Natural Fancy Green Diamond (or potentially Green Tourmaline/Tsavorite/Peridot requiring physical testing, assuming a natural green crystal structure) · Rough / Uncut Crystal
Not applicable (Rough Stone) Cut
Carat
Estimated 0.85 carats based on human fingerprint scale
Color
Fancy Intense Green
Clarity
Included (I1 equivalent for rough)
Shape
Rough / Uncut Crystal
Overall Assessment
A striking vivid green rough crystal offering exceptional color saturation. Professional gemological testing (spectroscopy) is mandatory to confirm diamond identity versus alternative green gem minerals.
Cut Quality
Not applicable (Rough Stone)
Brilliance
Vitreous to sub-adamantine luster with localized intense green flash
Fire
Low to moderate dispersion due to rough crystal state and intense body color
Scintillation
Limited flash effect primarily from natural unpolished windows
Proportions
Natural uncut proportions with irregular depth and natural octahedral/dodecahedral faces
Symmetry
Asymmetrical Natural Crystal Habit
Polish
Unpolished Natural Surface / Raw Crystal Facets
Fluorescence
Likely inert to medium yellow-green under UV
Inclusions
Internal cloudiness, feathered inclusions typical of rough stones
Blemishes
Natural surface etch channels, trigons, and minor chips on edges
Origin
Natural alluvial or primary kimberlite pipe deposit
Treatment Detection
Natural coloration suggested by surface radiation spots (skin), but laboratory testing required to rule out artificial irradiation
Estimated Value
Varies widely based on exact mineral composition; natural green colored diamonds command premium prices ($10,000+ per carat depending on saturation)
Certification Estimate
GIA Colored Diamond Report (Natural Origin)
Investment Potential
High for certified natural green diamonds due to extreme rarity; speculative if species is unconfirmed
Similar Diamonds
Natural green rough diamonds, green tsavorite garnet, or green tourmaline crystals
Setting Suggestions
Bezel setting in yellow or white gold to protect raw edges and accentuate the vibrant green hue
Care & Maintenance
Avoid ultrasonic cleaners and harsh chemicals; store separately to prevent scratching other gemstones
Interesting Facts
Natural green diamonds are extremely rare and typically get their color from natural radioactive radiation in the earth over millions of years
