Likely Natural Diamond or Simulant (Simulants like CZ are common in this style of costume setting) · Round Brilliant
Good to Fair (The facets appearing somewhat irregular and the pavillion depth looks slightly shallow) Cut
Carat
Approximately 0.75 - 1.00 carats (estimated by scale against fingertips)
Color
Likely H-J (Near Colorless) - shows slight warmth which may be reflected from the yellow gold setting
Clarity
Estimated SI1-I1 (Visible inclusions and internal graining appear present in the center and near the 10 o'clock position)
Shape
Round Brilliant
Overall Assessment
A classic round brilliant stone in a traditional yellow gold mounting; visually attractive for daily wear but likely commercial grade rather than investment quality.
Cut Quality
Good to Fair (The facets appearing somewhat irregular and the pavillion depth looks slightly shallow)
Brilliance
Moderate; the stone shows decent return of white light but is hindered by clarity and cut profile
Fire
Low to Moderate; spectral colors are visible but not as vibrant as premium cut stones
Scintillation
Standard; some pattern of light and dark but lacks 'hearts and arrows' precision
Proportions
Table appears slightly large (est 60-64%), with a medium-to-thick girdle and standard pavilion depth
Symmetry
Good (Facet meets appear mostly aligned, though girdle thickness looks uneven)
Polish
Good (Surface reflects light well but shows some minor wear marks)
Fluorescence
Indeterminate without UV light source
Inclusions
Visible crystals and feather-like structures near the table area and bezel facets
Blemishes
Minor surface scratches and 'flea bites' common on worn jewelry
Origin
Geological origin likely if natural; no specific indicators of lab growth visible without instrumentation
Treatment Detection
No obvious signs of laser drilling or fracture filling, though yellow gold setting can mask tint treatments
Estimated Value
If natural: $1,200 - $2,500 depending on final grading; If CZ/Simulant: $20 - $50
Certification Estimate
Likely EGL or IGI for this quality level if natural; GIA would likely confirm a lower clarity grade
Investment Potential
Low; this is a commercial quality stone typically used for personal wear rather than investment appreciation
