Natural Diamond or Lab-Grown Diamond (Visual estimation suggests high possibility of diamond simulant such as cubic zirconia or moissanite due to dispersion and context, but requires thermal/electrical testing to confirm)
Natural Diamond or Lab-Grown Diamond (Visual estimation suggests high possibility of diamond simulant such as cubic zirconia or moissanite due to dispersion and context, but requires thermal/electrical testing to confirm) · Oval Brilliant
Very Good Cut
Carat
Estimated 2.0 to 3.5 carats based on palm scale comparison
Color
Estimated G-H (Colorless range)
Clarity
Estimated VS2 (Based on visual eye-clean appearance)

Oval Brilliant
Overall Assessment
An attractive, large oval brilliant cut gemstone resting in the palm. Professional gemological testing (such as a diamond tester or refractometer) is strongly recommended to definitively separate natural diamond from lab-created alternatives or simulants.
Cut Quality
Very Good
Brilliance
High white light return, strong brightness
Fire
High spectral dispersion, displaying vibrant rainbow flashes
Scintillation
Good play of light and dark areas as the stone moves
Proportions
Standard oval brilliant proportions with a moderate table size and acceptable depth
Symmetry
Good
Polish
Good
Fluorescence
Unable to determine without UV testing; likely None to Faint
Inclusions
No prominent inclusions visible to the naked eye
Blemishes
Minor surface wear or polishing marks possible under magnification
Origin
Unknown; potentially mined or laboratory-created
Treatment Detection
No obvious visible treatments detected by eye
Estimated Value
Varies widely from $20 (if synthetic simulant) to $15,000+ (if natural diamond with high color/clarity)
Certification Estimate
GIA or IGI if genuine diamond; uncertified commercial grade
Investment Potential
Low to moderate unless verified as a high-quality natural diamond of significant size
Similar Diamonds
Standard commercial oval brilliant cut stones of comparable dimensions
Setting Suggestions
Classic prong setting in platinum or 18k white gold to emphasize the oval shape and maximize light entry
Care & Maintenance
Clean regularly with warm soapy water and a soft brush; store separately to avoid scratching other jewelry
Interesting Facts
Oval cuts are designed to maximize perceived carat weight and elongate the finger when set in a ring
