Overall Assessment
The specimen presents as a high-quality diamond simulant. While aesthetically pleasing with high brilliance, the specific rainbow dispersion and facet geometry suggest it is not a natural carbon-based diamond.
Cut Quality
Good to Very Good (Modified facet pattern)
Brilliance
High (Strong return of white light)
Fire
Extreme (Rainbow dispersion typical of high-RI simulants like Moissanite)
Scintillation
Broad flash pattern; lacks the needle-like sparkle of natural diamond
Proportions
High crown, deep pavilion, large table percentage consistent with stimulants
Symmetry
Good (Facet junctions show slight misalignment)
Polish
Excellent (High surface luster)
Fluorescence
None apparent in shown lighting
Inclusions
No internal inclusions visible; characteristic of synthetic stimulants
Blemishes
Minor surface abrasions on facet edges
Origin
Laboratory created (Simulant)
Treatment Detection
N/A (Synthetic formation)
Estimated Value
$50 - $400 USD (Reflective of simulant market value)
Certification Estimate
Likely uncertified or sold with a generic brand certificate (e.g. GRA for Moissanite)
Investment Potential
Low (Simulants do not typically retain resale value)
Similar Diamonds
CZ premium cuts or Forever One Moissanite
Setting Suggestions
Platinum or 14k White Gold four-prong solitaire setting
Care & Maintenance
Clean with warm soapy water; avoid harsh chemicals that can dull the surface of some simulants
Interesting Facts
The high degree of 'fire' (spectral colors) seen in the top right facet is a primary indicator of a diamond alternative with higher dispersion than natural diamond.
