0.70 Ct. Blue Sapphire from Ceylon (Sri Lanka)

From the cool hills of Ceylon, where monsoon winds carry whispers of centuries of gem lore, this blue sapphire began its life deep in metamorphic rock, formed under heat and pressure that coaxed aluminum and trace elements into one of the most enduring gemstones on earth. Miners in Sri Lanka, guided by generations of local knowledge and a keen eye for the earths secrets, found rough that carried a promise of color and clarity, and that promise arrived at our workshop as a modest, rough crystal. At The Natural Sapphire Company we honor that journey, tracing provenance and working with local partners to ensure that each stone carries not just geological history, but a story of people and place. This sapphire, originating in the storied soils of Ceylon, is a living piece of that tradition. It has passed through patient hands, from the mine to the initial sorting, then to the cutter who studied the rough, responding to its internal structure to reveal a face that would reflect light with sincerity and depth.

Viewed closely, the gem reveals a transparent body weighing 0.70 carat, cut into a cushion shape with dimensions of 5.73 x 4.13 x 2.89 mm, and executed in a mixed brilliant cut that balances table sparkle with pavilion depth. Its clarity is graded as slightly included when evaluated at eye level, inclusions that are small companions rather than faults, often providing identifying fingerprints that connect the gem to its Sri Lankan origin. The color intensity reads as medium intense, a hue that sits in a versatile band between vivid saturation and wearable depth, offering a blue that is expressive but not overpowering. The polish on every facet is excellent, so that the mixed brilliant arrangement dances between flashes of fire and broader blue flashes, giving life when the light moves. The sapphire has been heat treated, a long accepted enhancement that stabilizes and improves color and clarity, and that was disclosed and noted as part of its story. These are not just technical facts, they are the reasons this stone will behave with grace in a jewel, they explain how it catches a morning light and how it will sit serenely against skin.

The design possibilities for a cushion shaped sapphire of this size are as varied as the stories of those who will wear it. In an engagement ring it can anchor a classic four prong setting that lifts the stone to catch light from all angles, or it can be embraced by a halo of small brilliant diamonds that amplify the perceived size and add scintillation around its medium intense blue. A bezel or partial bezel mount will protect the slightly included girdle areas and suit a wearer who prefers everyday durability, while an open back setting will maximize light return and deepen the visible color. This gem will translate beautifully into a pendant, where a tailored bail and a simple bezel can render a modern keepable, or into a delicate stud that pairs one sapphire with a sister stone, or with diamonds set in a trilogy ring that echoes past, present, and future. White gold and platinum will sharpen the stone’s cool blue, yellow gold will warm the tone and lend a vintage sentiment, and rose gold will create an unexpected, romantic contrast. For those who want a bespoke statement, imagine asymmetric side stones in kite or baguette cuts that hug the cushion, or a floral cluster that tucks the sapphire into a garden of petals in mixed metals. The gem’s modest carat weight and judicious dimensions open the door to secret design choices such as East West orientation for a modern twist, low profile signet settings for menswear, or a halo with milgrain and filigree for an antique look. At The Natural Sapphire Company our bench will create CAD sketches, metal mockups, and wax models so you can see the sapphire in context, and we advise on prong count, bezel thickness, and under gallery design to ensure the sapphire performs as envisioned every day.

Owning this Ceylon sapphire is both a personal and a cultural connection, a link to antiquity and to craftsmen who have for generations associated these blues with loyalty, wisdom, and protection. We at The Natural Sapphire Company treat that connection with care, offering guidance on settings that will preserve the stone and amplify its story.
