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

A rare greenish blue sapphire of exceptional character, this 0.30 carat cushion shaped gem invites a discerning collector to claim something truly singular, something not easily replicated. Hailing from the storied mines of Ceylon, Sri Lanka, each facet tells a story of ancient earth and careful human craft, a lineage that has long produced sapphires prized by connoisseurs and royalty alike. Its greenish blue hue reads as both ocean and forest, a color that shifts with light and angle, offering a private, changing display that resists mass production. When a gem like this appears in our selection at The Natural Sapphire Company, it is presented not as one of many, but as a discreet opportunity to join an exclusive circle of owners who recognize the language of fine sapphires, those who understand that true rarity is not only in the material itself, but in the precision of cut, the intensity of color, and the intimacy of wear.

Technically refined yet emotionally compelling, this sapphire measures 4.58 by 3.55 by 2.27 millimeters, and its cushion shape with a mixed brilliant cut has been executed to enhance scintillation without sacrificing the gem’s natural depth. At 0.30 carat, it sits at a perfect threshold where presence meets wearability, allowing a jeweler to craft a bold statement that remains elegant and refined. The polish is excellent, delivering a smooth, reflective surface that allows light to dance across the pavilion and crown with compelling brightness. Clarity is graded as slightly included when evaluated at eye level, a quality that in sapphires often contributes to a unique internal character, while remaining visually clean to the naked eye. Heat treatment has been applied, a standard and stable enhancement that intensifies the stone’s color to an intense saturation, revealing the vivid greenish blue tones for which Ceylon sapphires are celebrated.

What makes this particular gem ideal for a statement piece is the rare harmony between its size and clarity, a harmony that allows a relatively modest carat weight to read as commanding on the finger or in a pendant. The cushion silhouette provides a broad visual face, maximizing perceived size while the mixed brilliant cut multiplies flashes of light, creating a lively table that catches attention from a distance and rewards closer inspection. Slight inclusions contribute to the gem’s personality without detracting from its brilliance, so that in a solitaire ring or a bespoke halo setting the stone will project presence rather than merely occupy space. Shown against the hand, it sits with confident poise, small enough to be practical for daily wear, and large enough to make a clear stylistic statement. For clients seeking something distinct yet wearable, this sapphire offers the best of both worlds, a jewel that reads as intentional, curated, and unmistakably luxurious.

At The Natural Sapphire Company we present this Ceylon greenish blue cushion sapphire as a private offering, ready to be set in a custom design that reflects your personal taste and the singular quality of the gem. We can recommend settings that amplify its table and color, from bezel frames that concentrate the hue, to fine milgrain settings and custom halos that enhance perceived size and glamour. Given the gem’s limited availability and distinctive character, commissions are handled with care and discretion, ensuring that each finished piece remains as exclusive as the stone itself. Our gemological team can provide further details about the stone’s evaluation and treatment, and we offer bespoke design consultations to realize your vision. If you seek an heirloom quality sapphire that will announce your taste with quiet authority, this 0.30 carat Ceylon cushion is a rare chance to own something truly exceptional, a jewel that marks you as part of an elite few who possess both the eye to choose and the means to secure such subtle rarity.
