1.33ct Precision-Cut Cornflower Blue Sapphire

GRC Certified | Hand-Measured 6.48×5.50mm | Collector's Gem

A Masterclass in Sapphire Cutting

"This 1.33ct sapphire represents cutting perfection - its 4.33mm depth creates extraordinary light return while maintaining that signature velvety cornflower blue. The 6.48mm length gives impressive presence without sacrificing color intensity." - Gembear Master Gemologist

Why This Sapphire Stands Out

  • Premium Size: 1.33ct with ideal 6.48mm face-up presence
  • Precision Cut: 4.33mm depth optimized for color and brilliance
  • Color Mastery: True cornflower blue with velvety texture
  • Certification: GRC report included (5-day processing)
  • Hand-Verified: Each dimension manually confirmed
  • Investment Quality: Collector-grade proportions

The Art of Precision Cutting

Cutting Advantages

  • 66.8% depth-to-width ratio
  • 1.18 length-to-width proportion
  • 58° crown angle
  • 42° pavilion angle

Visual Impact

  • Eliminates windowing effect
  • Prevents excessive darkness
  • Maximizes color consistency
  • Creates lively brilliance

The cutter achieved near-perfect proportions: The 4.33mm depth (66.8% of width) prevents light leakage while the 1.18 length-to-width ratio creates a classic oval silhouette. These angles work synergistically to maintain the cornflower blue's velvety appearance while ensuring exceptional sparkle.

Designer's Dream

  • Center stone rings
  • Statement pendants
  • High jewelry pieces
  • Collector's items
  • Investment gems

Technical Specifications

Carat Weight 1.33 carats
Measurements 6.48×5.50×4.33mm (hand-verified)
Cut Quality Excellent (precision cut)
Shape Oval (1.18 ratio)
Certification GRC (5-day processing)
Color Cornflower Blue (velvety)
Treatment Heated (industry-standard)

Cutting Insight: The 4.33mm depth represents a master cutter's solution to the cornflower blue paradox - maintaining the velvety texture while preventing dullness. At 66.8% of the width, it's precisely deep enough to concentrate color, yet shallow enough to avoid dark areas. The 6.48mm length gives impressive presence (visible even in elaborate settings) while the 5.50mm width ensures the stone doesn't appear narrow.
