Owner's Notes
x1.36ct Vivid Cornflower Blue Sapphire
GRC Certified | 6.47×5.17mm | Owner's Recommended Selection
The Epitome of Cornflower Blue
"This 1.36ct sapphire captures the perfect balance of cornflower blue's signature velvety texture with exceptional vibrancy. The 4.29mm depth intensifies the color while the 6.47mm length gives it impressive presence - exactly why we've selected it as our owner's recommendation." - Gembear Team
Why We Recommend This Stone
- Ideal Weight: 1.36ct - substantial without color dilution
- Vivid Color: Intense cornflower blue saturation
- Perfect Proportions: 6.47×5.17×4.29mm dimensions
- Certification: GRC report included (5-day processing)
- Cut Quality: Excellent light return
- Owner's Pick: Personally selected for exceptional quality
Color Science Behind This Sapphire
| Feature | Measurement | Ideal Range |
|---|---|---|
| Length-to-Width Ratio | 1.25 (6.47/5.17) | 1.15-1.35 |
| Depth Percentage | 66.3% (4.29/6.47) | 60-70% |
| Table Percentage | 59% | 55-65% |
| Color Intensity | Vivid (Owner's Grade) | Medium-Strong to Vivid |
The 1.25 ratio creates an elegant slightly elongated oval, while the 66.3% depth percentage concentrates the cornflower color beautifully. What makes this stone exceptional is how the 4.29mm depth works with the vivid saturation to create that rare "glowing from within" effect that defines top cornflower sapphires.
Recommended Applications
- Signature engagement rings
- Designer cocktail rings
- Statement pendants
- High-end earrings
- Investment collection
Technical Specifications
| Carat Weight | 1.36 carats |
| Measurements | 6.47×5.17×4.29mm |

Owner's Commentary: We specifically chose this 1.36ct sapphire for our recommended collection because it solves the common trade-off in cornflower blues - many stones either have the velvety texture but lack vibrancy, or have vivid color but lose that distinctive cornflower character. This stone achieves both: The 4.29mm depth intensifies the color while the precise cutting preserves that velvety glow. At 6.47mm length, it has impressive presence without crossing into the size where cornflower blues typically lose saturation.
