1.18 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Long before this sapphire reached a jeweler’s workbench, it began its life deep within the ancient rocks of Ceylon, where heat and pressure over millennia coaxed aluminum and trace elements into a crystalline form that captures sunlight in every facet. Miners in Sri Lanka have long known how to read the ground, following pockets of corundum with the patience of generations, and this stone was brought to the surface with those hands and that knowledge. At The Natural Sapphire Company we tell that story as part of each gem’s identity, because the land where a sapphire forms leaves an imprint on its color and character. The rich cultural history of Ceylon sapphires, carried across time in crowns and talismans, is present in the deep blue of this cushion, a color that seems to hold the monsoon sky within a single stone.

When you examine the gem closely you find exacting proportions and craftsmanship. The sapphire weighs 1.18 carat, with dimensions of 6.28 x 6.23 x 3.18 mm, formed into a cushion shape that balances rounded elegance with a modern silhouette. The cutter chose a mixed brilliant cut to enhance both scintillation and depth, permitting flashes of light from the crown while preserving a velvety pavilion that deepens the overall tone. Clarity is described as very very slightly included evaluated at eye level, which means to the naked eye this stone reads as transparent and clean, while minor inclusions remain tucked within, invisible in daily wear. Its color shows vivid intensity, a saturated blue that reads alive and immediate, and an excellent polish gives every facet a mirror finish. The sapphire has been heat treated, a common and stable enhancement that refines color and clarity, fully disclosed and part of our commitment to transparency.

For anyone seeking a statement piece, the combination of size and clarity here is particularly compelling. At just over one carat and with near perfect visual clarity, the stone carries presence without overwhelming, sitting with confidence on a solitaire mounting or forming the luminous center of a halo design that enhances its vivid blue. The cushion outline aids in perceived size, the rounded corners and broad table maximizing visible surface area, while the mixed brilliant faceting scatters light in lively patterns that draw the eye. On a finger the gem reads like a beacon, not because it is exaggerated in scale, but because its clarity allows color to shine through unimpeded, and its cut projects fire and depth in equal measure. This balance makes the sapphire ideal for a bold engagement ring, a striking pendant, or a singular cocktail ring that announces taste and restraint at once.

Bringing this sapphire from mine to mounting is a careful process at The Natural Sapphire Company, where each step honors the gem’s journey. Our cutters and polishers work to preserve as much original rough as possible while achieving the symmetry and finish that modern settings demand. We disclose the heat treatment that brings out its vivid hue, and we present the gem with full details so you can appreciate both its natural story and its crafted beauty. For the buyer who values provenance and presence, this cushion shape Ceylon sapphire offers a tangible connection to the earth and to centuries of gem tradition, matched to a size and clarity that will remain striking for decades. If you imagine this stone anchored in a ring, picture light finding every facet, color that remains rich from every angle, and a silhouette that reads as decisive and elegant, a statement piece crafted not only to be seen, but to be cherished.
