"Finding two sapphires with identical cornflower blue color and matching proportions is exceptionally rare. This pair maintains less than 0.02ct weight difference and near-identical face-up sizes - a true designer's dream for symmetrical jewelry." - Gembear Gemologist
Cornflower blue sapphires display a distinctive velvety blue that's slightly lighter than royal blue but with exceptional vibrancy. This pair achieves the perfect balance:
Feature | 0.68ct Sapphire | 0.66ct Sapphire |
---|---|---|
Measurements | 6.21×4.11×3.11mm | 6.16×4.18×2.80mm |
Face-Up Area | 25.5mm² | 25.7mm² |
Depth Percentage | 50.1% | 45.4% |
The minimal 0.05mm length difference and nearly identical face-up areas (25.5mm² vs 25.7mm²) make these appear as twins to the naked eye, while the complementary depth percentages ensure consistent light performance.
Total Weight | 1.34ct (0.68ct + 0.66ct) |
Dimensions | 6.21×4.11mm & 6.16×4.18mm |
Shape | Matched oval pair |
Certification | CMA (China National Testing Center) |
Color | Cornflower Blue (matched) |
Price | $333 USD (¥2,400) for pair |
Verification | Lab re-check available |
Pairing Insight: We calculated this pair at 1600×1.5/7.2 to offer exceptional value at $333 (¥2,400). The 0.02ct weight difference is undetectable visually, while the complementary dimensions (6.21mm vs 6.16mm length) actually create better visual harmony in finished jewelry than mechanically identical stones would. The slight variation prevents the "too perfect" look that can appear artificial.
