Simulant (Glass/Crystal Decorative Object)
Simulant (Glass/Crystal Decorative Object) · Round Brilliant (Modified/Large-faceted)
Poor (Generic decorative cut with non-standard faceting ratios) Cut
Carat
Estimated >100 carats (based on scale and visual indicators)
Color
Fancy Green (Artificial/Concentrated)
Clarity
I1-I2 (Visible internal fractures and air bubbles characteristic of glass)
Shape
Round Brilliant (Modified/Large-faceted)
Overall Assessment
The object is a decorative glass simulant. It lacks the refractive index, hardness, and precision cutting characteristic of a genuine diamond or higher-end lab-grown alternative.
Cut Quality
Poor (Generic decorative cut with non-standard faceting ratios)
Brilliance
Low (Significantly lower refractive index than carbon-based diamond)
Fire
Minimal (Low dispersion compared to real diamond or Moissanite)
Scintillation
Weak and dull; lacks the high-contrast light-dark pattern of an expertly cut diamond
Proportions
Thick girdle, shallow crown, overly deep pavilion relative to standard diamond metrics
Symmetry
Fair to Poor (Visible misalignment of facets on the crown and pavilion)
Polish
Fair (Visible surface abrasions and rounded facet junctions)
Fluorescence
None observed
Inclusions
Large internal fractures, circular gas bubbles (typical of glass), and swirled color zoning
Blemishes
Minor surface scratches and chipping on the facet edges
Origin
Manufactured/Industrial (Likely glass or acrylic production)
Treatment Detection
N/A (Homogeneous colored material, likely glass dye)
Estimated Value
$5 - $20 USD (Decorative value only)
Certification Estimate
N/A (Would not be accepted for grading as a gemstone by GIA/AGS)
Investment Potential
None (This is a decorative novelty item)
Similar Diamonds
Green CZ (Cubic Zirconia) would be the closest optical simulant, but this appears to be glass
Setting Suggestions
Display stand or paperweight (Too brittle and large for standard jewelry)
Care & Maintenance
Clean with a soft damp cloth; avoid high heat which may cause the glass to crack
Interesting Facts
Green is one of the rarest natural diamond colors, usually caused by radiation exposure over millions of years
