Likely Lab-Grown Diamond or High-Quality Moissanite · Radiant Cut (Elongated)
Very Good Cut
Carat
Estimated 3.00 - 4.50 carats
Color
Visual G-H (Near Colorless) with a slight greenish-yellow tint
Clarity
Estimated VS1 - VS2 (Very Slightly Included)

Radiant Cut (Elongated)
Overall Assessment
A large, impressive-looking stone with high brilliance and fire. The elongated shape is currently very trendy. Visual cues like doubling of facets suggest it could be a high-end Moissanite rather than a Diamond.
Cut Quality
Very Good
Brilliance
Strong internal light return with characteristic 'crushed ice' look
Fire
Very high dispersion; rainbow flashes are prominent, suggestive of Moissanite properties
Scintillation
Dense, high-frequency sparkle pattern
Proportions
Deep pavilion with a relatively large table, typical of commercial radiant cuts
Symmetry
Good to Very Good
Polish
Good
Fluorescence
None visible, though lighting creates blue flaring
Inclusions
Few pinpoints and small feathers visible under magnification; overall eye-clean appearance
Blemishes
Minor surface abrasions on crown facets
Origin
Likely Lab-Grown (CVD or HPHT processes)
Treatment Detection
No obvious secondary treatments; suspected HPHT growth if Diamond
Estimated Value
$1,500 - $3,500 USD (if Lab Diamond); $300 - $600 (if Moissanite)
Certification Estimate
IGI or GIA Lab-Grown Report; Near Colorless/VS2
Investment Potential
Low; lab-grown stones and simulants do not retain significant resale value

Platinm or White Gold 4-prong solitaire or hidden halo to accentuate length
Care & Maintenance
Ultrasonic cleaner safe; regular degreasing with mild soap to maintain brilliance
