4.53 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite transparent blue sapphire from Ceylon is a study in classical beauty and measured precision, a gemstone that speaks to both the ancient and the modern collector. Weighing 4.53 carats, and measuring 9.69 x 9.74 x 6.12 mm, this round shape sapphire has been fashioned in a mixed brilliant cut that balances scintillation with depth. The stone displays an intense color intensity that draws the eye with a saturated, pure blue tone, and its excellent polish allows light to dance cleanly across each facet. At eye level the clarity is graded as slightly included, which affirms the natural character and origin of the sapphire, while the enhancement noted is heat treated, a widely accepted practice that stabilizes and enhances color without compromising the gem s natural identity. As with every piece that bears our name, The Natural Sapphire Company presents this sapphire with full disclosure of its origin and treatments, so you may wear it with confidence and appreciation for its natural story.
