0.90 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One exemplary treasure from The Natural Sapphire Company awaits the connoisseur of finely crafted gemstones, a transparent blue sapphire weighing 0.90 carat, presented in an elegant oval shape with dimensions 5.85 by 4.85 by 3.87 millimeters. This gem has been fashioned with a mixed brilliant cut, and it carries a clarity grade described as very very slightly included when evaluated at eye level, ensuring an immaculate face up appearance that speaks of rarity. Its color intensity is intense, a saturated vivid blue that arrests the gaze, and the polish is excellent, enabling every facet to act as a window for light. This sapphire has been heat treated, a traditional and stable enhancement that reveals the stone as nature intended, and its provenance is Ceylon, Sri Lanka, a historic source of sapphires known for producing stones of exceptional hue and character. From measurements to treatment, each specification has been selected and communicated with the meticulous care that defines The Natural Sapphire Company, and the result is a jewel that balances scientific precision with timeless allure.

The mixed brilliant cut is the key to how this sapphire embodies both scintillation and depth, and it is here that the cutter has translated the stone into an object of light. By combining brilliant style facets on the crown with a more controlled pavilion geometry, this cut channels incoming light to create a lively dance of pinpoint flashes that coexist with broad, velvety planes of color. The crown facets break light into a sequence of scintillating reflections, while the pavilion facets, arranged to a proportion that respects the stone dimensions, return that light through the face as saturated color and luminous contrast. With an overall depth of approximately seventy two percent relative to the average diameter, the gem possesses a fullness that enhances its color saturation, without sacrificing the vitality of its surface brilliance. The mixed brilliant approach excels in oval shapes because it preserves the elongation and elegance of the outline, while optimizing facet angles for maximum light return, resulting in a gem that appears larger than its weight suggests, and more alive with motion whenever it encounters light.

Color and clarity find their perfect stage in this sapphire, where the intense blue tone is both deep and illuminated from within. Ceylon sapphires are celebrated for their velvety cornflower to royal blue spectrum, and this example leans into that legacy with an intensity that is bold yet refined. The transparency and very very slight inclusions mean that light travels through the crystal lattice with minimal interruption, allowing the mixed brilliant facets to fragment and recompose that light into vivid flashes and soft color fields. The heat treatment has been applied with restraint and expertise, stabilizing the chromophore distribution to enhance hue and saturation while preserving the natural character of the stone. When set in a fine mounting, the sapphire will yield a dual optical performance, offering crisp scintillation at every turn, and a profound, even blue when observed face on. Excellent polish is the finishing touch that removes any microscopic roughness, so that reflections are crisp, contrast is heightened, and the surface behaves like a perfect mirror to the light that animates the stone.

To own this sapphire is to claim an object that speaks of cultivated taste and discerning choice, a jewel that translates geological time into a personal emblem of refinement. The Natural Sapphire Company presents this 0.90 carat oval blue sapphire as an invitation to elevate an heirloom or to craft a contemporary statement piece, with the assurance of expert sourcing and responsible treatment disclosure. Imagine this gem in a classic solitaire ring where the oval silhouette lengthens the finger, or nestled within a bespoke pendant where the mixed brilliant cut will catch candlelight and daylight alike, offering both dazzling moments and a steady, sumptuous blue. For the collector who prizes provenance, the Ceylon origin imparts an additional layer of story, a provenance associated with generations of master cutters and discerning buyers. Selecting this sapphire is more than an acquisition, it is an affirmation of style, an act that marks a significant milestone in a life well curated, and a confident expression that the wearer understands both beauty and the craft that reveals it.
