0.85 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

From the moment this sapphire formed deep within the ancient metamorphic rocks of Ceylon, a slow and patient geological story began that would span millions of years, flowing water, shifting earth, and the heat and pressure that coaxed corundum into being. In Sri Lanka, gem gravels have been worked for centuries, and miners with generations of knowledge still seek the pockets where light will be captured and held. This greenish blue sapphire, with its origin in Ceylon, carries that layered history like a secret held close. It is a stone born of rain and rock, of rivers that polished its rough surface and of the island winds that have seen kingdoms rise and fall, a stone whose color recalls moonlit lagoons and the depths of warm tropical seas. At The Natural Sapphire Company we honor that beginning, and we celebrate this gem as part of a long tradition of Sri Lankan sapphires that have graced royal collections and museum showcases, each piece a fragment of natural time translated into color and light.

When you hold the 0.85 carat cushion shape greenish blue sapphire you can feel the care taken to present the stone at its best, from raw beauty to carefully faceted gem. The stone measures 5.22 x 4.92 x 3.46 mm, a compact and elegant size that suits a refined setting, yet its presence is larger than its weight suggests. Cut in a faceted mixed brilliant style, the pavilion and crown work together to balance sparkle with depth, so that each facet returns light with lively scintillation and the cushion outline offers a timeless silhouette. The clarity is evaluated as very very slightly included at eye level, which means that to the unaided eye the gem reads as transparent and clean, a rarity in small stones that often trade clarity against color. The color intensity is vivid, a saturated greenish blue that shifts a hair toward teal in certain lights, and the polish is excellent so that each facet surface is smooth and reflective. Importantly, the stone is natural and unenhanced, a pure, untreated sapphire that reveals its original color and structure without any laboratory intervention.

Comparisons to the great sapphires of history help place this gem in context while highlighting what makes it uniquely valuable. Kashmir sapphires have long been celebrated for their velvety cornflower blue, and Burmese sapphires are prized for their saturated royal blue. Ceylon sapphires, which share a lineage with this stone, are known for their lively, luminous tones and for a clarity that allows light to dance through the gem. The famous Star of India, one of the most celebrated sapphires, also hails from Sri Lanka, and that piece exemplifies the storied heritage of Sri Lankan mines. This 0.85 carat cushion greenish blue stands apart from those famous examples not by grand size, but by the intriguing balance of color and clarity, and by being unheated. Many historical and contemporary market stones undergo heat treatment to improve color, but this sapphire retains its vivid hue naturally, an attribute often sought after by collectors who prize provenance and authenticity. The mixed brilliant cut maximizes fire and return of light in a way that recalls the careful recutting histories of museum stones, where cutters worked to reveal the best optical personality of each fragment of corundum. In short, while it will never be a museum sized wonder, it possesses an innate character and honesty that echoes the noble lineage of famous sapphires.

This gem is a storyteller made tangible, ready to begin a new chapter in wear and design with you. At The Natural Sapphire Company we see pieces like this as invitations, small but potent, to craft a personal legacy. Imagine the cushion mounted in a simple bezel to emphasize its color, or set in a delicate solitaire with a slender band so that light can embrace the stone from every angle. Its measurements and mixed brilliant faceting make it a versatile centerpiece for an engagement ring, a refined cocktail ring, or a pendant that sits close to the heart. The durability of corundum means it will stand up to daily life with the proper care, and its vivid greenish blue will continue to shift and surprise as it moves through different lights and seasons. If you seek a natural, untreated Ceylon sapphire that ties the ancient geological soul of Sri Lanka to contemporary design, this 0.85 carat cushion from The Natural Sapphire Company is a rare conversation between earth and artisan, ready to be worn, cherished, and passed along as a new story for someone to inherit.
