0.68 Ct. Blue Sapphire from Ceylon (Sri Lanka)

There are gems that seem to carry a small, secret sky inside them, a pocket of twilight that will not be tamed, and this 0.68 carat asscher octagon blue sapphire carries such a sky. Imagine a deep, vivid blue that breathes with the patience of the ocean and the hush of evening, cut into crisp concentric steps that draw light inward and release it again like a held breath. From The Natural Sapphire Company this stone arrives with a presence that is both intimate and noble, its dimensions of 4.90 by 4.83 by 3.26 millimeters balanced precisely to the eye. The asscher cut gives the sapphire an architectural elegance, every facet a tiny window into color and fire, its excellent polish like satin on the surface of a midnight lake. Heat treated to enhance clarity and tone, and originating from the storied soils of Ceylon, Sri Lanka, this sapphire is a piece of earth that has been coaxed into a jewel, ready to be set into the piece of your heart.

Under closer, tender inspection this gem reveals a clarity grade of very slightly included as evaluated at eye level, meaning that to the lover who holds it it appears nearly flawless, an eye clean secret kept by the stone itself. Its vivid color intensity is the jewel’s song, a saturation that reads as true blue rather than steel, that flares to life under candlelight and deepens into majestic calm in daylight. The asscher cut, with its octagon silhouette and trimmed corners, interacts with light differently than round or oval shapes, creating step-like flashes and an internal geometric dance that feels at once vintage and modern. The excellent polish makes each facet a mirror, reflecting back the warmth of the wearer and the surrounding world, and the measured proportions of its little body ensure it catches attention without ever overwhelming a delicate setting. This is a piece meant to be cherished up close, a gem that favors whispers and secret vows.

Because a sapphire is most at home when embraced by a thoughtful setting, consider how many voices your design can sing. Picture this Asscher octagon sapphire in a classic solitaire ring, held with four delicate corner prongs that allow the light to pass through the pavilion while protecting the faceted corners, a slender band of platinum that frames the blue as if it were a private lake. Imagine a halo of fine pavé diamonds circling it, each small light intensifying the sapphires color, making the center appear larger and more luminous, perfectly suited to an engagement ring that feels both timeless and radiant. For someone who lives loudly, a bezel mount offers modern security, the metal rim cradling the stone and emphasizing the geometry of the asscher faceting, available in warm yellow gold to set off the sapphire with contrast, or in rose gold for a romantic whisper. A three stone ring, with tapered baguettes or tapered sapphires on either side, transforms the single center into a story of past present and future, each side stone a chapter that complements the central sky.

The versatility continues beyond rings, for this gem is ready to become an heirloom in many forms. Set as the heart of a pendant, it becomes a talisman close to the throat, its vivid blue catching every turn and word. As a stud, paired with a diamond or framed in delicate milgrain for vintage flair, it lends an air of quiet elegance to daily life. For a bespoke brooch or a pair of earrings, our craftsmen can source matching accent stones and work harmoniously with the asscher geometry to create symmetry and motion. Consider a signet reset where the sapphire sits flush in a sculpted gold bezel for a modern gentlemans ring, or a lariat necklace where the stone nods at the end of a chain like a single blue note. Metal choices will alter the poem the sapphire tells, platinum and white gold lending clarity and contrast, yellow gold conjuring warmth and old world romance, rose gold invoking softness and intimacy. Our design team at The Natural Sapphire Company will assist with CAD renders, hand sketches, and practical advice on prong styles and band proportions that best suit the stones measurements, ensuring the final piece is as wearable as it is poetic.

If you can imagine a love letter shaped like a jewel, this Ceylon sapphire is inked and waiting. It carries the provenance and care of its origin, heat treatment that stabilizes and enriches its tone, and proportions that invite endless creative collaboration. Let us at The Natural Sapphire Company help you explore rings with split shanks, vintage filigree settings that echo the step facets, tension settings that float the stone between arms of polished metal, or clustered designs where smaller diamonds and sapphires orbit the center. We offer personal consultations, bespoke design paths, and expert mounting recommendations to protect the corners and maximize the life of the gem. With gentle maintenance, occasional professional cleaning and a thoughtful mount, this small but vivid sapphire will become a quiet declaration, an heirloom that gathers the light of your days and keeps it close, a small sky you can carry always.
