4.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Imagine slipping a cushion of luminous Ceylon blue against your skin, a 4.03 carat cushion shape sapphire with dimensions of 9.58 x 8.61 x 5.56 mm, a gem that radiates warmth and promises. As a gemstone specialist at The Natural Sapphire Company, I can tell you this stone is a rare combination of perfect proportions and emotional resonance. The mixed brilliant cut delivers an irresistible, lively sparkle, while the vivid color intensity evokes the deep, velvety blues of the Indian Ocean and the skies above Sri Lanka. Clarity has been graded very slightly included evaluated at eye level, which means the gem remains eye clean and pure to the heart, and the excellent polish allows every facet to sing with light. Heat treated to enhance its natural hue, and hailed from Ceylon Sri Lanka, this sapphire carries provenance and personality, ready to become the heart of a bespoke design that captures joy, commitment, and celebration.

This sapphire is especially ideal for custom jewelry because its cushion shape and size make it supremely versatile and wearable. At 9.58 x 8.61 x 5.56 mm the stone sits beautifully as a solitaire engagement ring, offering a comfortable profile and generous presence without overwhelming the hand. Its soft, rounded corners lend themselves to heirloom inspired halo settings, romantic vintage designs, and secure bezel mounts for everyday elegance. The mixed brilliant cut creates a perfect marriage of depth and scintillation, which pairs beautifully with diamond shoulders, colored gem accents, or intricate metalwork. Picture this sapphire set into a delicate platinum halo for a forever engagement ring, or suspended in a simple gold pendant that catches the light each time you move, a constant reminder of a milestone or a promise. Choosing this gem from The Natural Sapphire Company means choosing a stone that is not only visually breathtaking but also practically suited to skilled craftsmanship, making your custom piece a living memory to pass down through generations. I would be delighted to help you design a piece that transforms this extraordinary 4.03 carat Ceylon cushion sapphire into an expression of love, joy, and lasting beauty.
