High brightness with notable white light return
Fire
Very High; the extreme 'rainbow' dispersion is characteristic of Moissanite rather than natural diamond

Symmetry
Good
Polish
Good

Estimated Value
$50 - $400 if Moissanite/CZ; $15,000 - $35,000 if Natural Diamond
Certification Estimate
GRA (Global Gemological Reseach Academy) for Moissanite, or IGI/GIA if Natural
Investment Potential
Low (aesthetic value only if synthetic; strong resale only if natural)
Similar Diamonds
Comparable to high-quality Moissanite or CVD lab-grown diamonds
Setting Suggestions
Classic solitaire or a halo setting in Platinum or 14k White Gold to enhance the colorless appearance
Care & Maintenance
Clean with mild soap and warm water using a soft brush; avoid harsh chemicals
