Likely Natural White Zircon or Sapphire (Substantial doubling of facet edges and warmer body color suggest it is not a diamond)
Likely Natural White Zircon or Sapphire (Substantial doubling of facet edges and warmer body color suggest it is not a diamond) · Round Brilliant
Fair (Lack of crisp facet meet points and shallow reflection) Cut
Carat
Estimated 1.25 to 1.75 carats based on visible diameter
Color
Estimated K-M (Visible yellowish/warm tint)
Clarity
I1-I2 (Visible internal fractures and significant surface reaching inclusions)
Shape
Round Brilliant
Overall Assessment
The specimen shows optical characteristics, such as facet doubling and lower refraction, that are atypical of a high-quality diamond. It is likely a natural white gemstone or a lower-tier diamond stimulant.
Cut Quality
Fair (Lack of crisp facet meet points and shallow reflection)
Brilliance
Low (Stone appears somewhat glassy rather than having the high refractive index of a diamond)
Fire
Low (Minimal spectral color dispersion)
Scintillation
Moderate (Lacks the intense sparkling pattern of a high-grade diamond)
Proportions
Moderate table; slightly shallow depth based on light leakage in the center
Symmetry
Good (Facet alignment is generally regular but lacks precision)
Polish
Fair (Surface appears abraded with visible scratches)
Fluorescence
Cannot determine without UV light; specimen appears dull
Inclusions
Significant clouds, feathers, and potential crystals visible to the naked eye
Blemishes
Surface abrasions and potential chips on the girdle edges
Origin
Likely natural mined origin (based on inclusion patterns indicative of natural growth)
Treatment Detection
None obvious; surface abrasions suggest an untreated stone of lower hardness
Estimated Value
$150 - $400 USD (If a natural stone like Zircon/Sapphire); significantly less if synthetic stimulant
Certification Estimate
GIA or IGI (Likely to receive a Color/Clarity certificate only, or identified as a stimulant)
Investment Potential
Low (Utility as a decorative gemstone only; unlikely to appreciate)
Similar Diamonds
K-color commercial grade earth-mined diamonds
Setting Suggestions
Bezel or 6-prong setting in Yellow Gold to complement the warm color and protect the edges
Care & Maintenance
Avoid ultrasonic cleaners if fractures are deep; clean with mild soap, warm water, and a soft brush
Interesting Facts
White Zircon was historically used as a diamond substitute before synthetics became common due to its high luster
