0.99 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the ancient courts of royalty to the quiet devotion of a modern engagement, the blue sapphire has carried a language of fidelity, wisdom, and timeless beauty across cultures and centuries. This 0.99 carat Ceylon sapphire, curated by The Natural Sapphire Company, is a continuation of that long story, a gemstone that echoes the classical appeal of historic jewels while offering a fresh and vibrant presence for today. The oval silhouette has been cherished since antiquity for its flattering proportions, and the mixed brilliant cut on this stone enhances that legacy by marrying scintillating light return with the elegant, elongated profile that sits beautifully against the skin. When you hold this sapphire, you are not simply admiring color, you are encountering a fragment of geological time, a stone formed deep within the earth and brought to life by generations of skilled cutters and the stewardship of a trusted house of gemstones.

Precise measurements and fine craftsmanship define this gem, which weighs 0.99 carat and measures 6.44 by 5.59 by 3.32 millimeters, presenting a balanced and wearable size for a ring, pendant, or bespoke piece. The clarity is graded as eye clean when evaluated at eye level, allowing the intense blue color to remain the focal point without distraction. The polish is excellent, allowing facets to play with light and create lively flashes across the surface, while the mixed brilliant cut delivers both depth and brilliance that elevate the sapphire beyond mere color into an object of refined optical performance. This sapphire has been heat treated, a standard and stable enhancement that enriches the stone without compromising its structural integrity, and its origin from Ceylon, Sri Lanka, ties it to one of the most storied sources of sapphires in the world, a place where mines have produced gems for centuries.

Durability is a hallmark of sapphire and an essential reason these gems have been favored for jewelry intended for daily wear through the ages, and this particular Ceylon sapphire is ideally suited for that purpose. On the Mohs hardness scale sapphire rates at 9, second only to diamond, and that exceptional hardness gives the stone strong resistance to scratching and abrasion during everyday activities. The gem also has robust toughness when properly set, and the excellent polish helps maintain its brilliance even after years of wear. Heat treatment, as applied to this sapphire, is widely accepted in the trade and does not weaken the crystal lattice or make the stone more susceptible to damage, so you can confidently choose this gem for a ring you intend to wear regularly. For practical longevity we recommend classic secure settings that protect the girdle and corners, such as a well crafted prong mounting with protective crowns or a bezel setting for extra security, and routine gentle cleaning with warm soapy water and a soft brush will preserve the stone’s intense color and mirror like facets.

Beyond its physical virtues this sapphire carries an enduring symbolic value that makes it an exceptional choice for those who appreciate heirloom quality and lasting style. A sapphire from Ceylon offers a particular expression of blue that is both vibrant and refined, a tone that transitions effortlessly from daytime elegance to evening formality, and its oval shape adapts gracefully to many design motifs, whether solitary and minimalist or haloed by diamonds for added brilliance. At The Natural Sapphire Company we are committed to helping you realize a piece that honors that history while meeting your personal preferences for durability and wearability, and our gem specialists are available to advise on settings, mounting profiles, and care so that this 0.99 carat Ceylon sapphire becomes a jewel you pass on with pride. Choose this stone for its storied origin, its meticulous cut and polish, and its dependable resilience, and you will carry a legacy of color and craftsmanship that truly endures.
