1.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.07 carat cushion shape blue sapphire presents exacting proportions, with dimensions of 5.50 x 5.48 x 3.66 mm, a mixed brilliant cut, and an overall finish that reflects thoughtful lapidary work. The clarity is graded as very slightly included when evaluated at eye level, offering an appealing balance between transparency and the natural character that gives origin to the stone. Color is a vivid blue with strong saturation and even distribution across the table and pavilion, and the polish is evaluated as excellent, contributing to lively luster and crisp facet junctions. This sapphire is untreated, with no enhancement, and its origin is Ceylon Sri Lanka, a provenance known for producing sapphires with lively, velvety blue tones. The Natural Sapphire Company presents this gem as a high quality natural example, suitable for collectors and bespoke jewellery commissions that emphasize both natural origin and uncompromised material integrity.

Visually, the cushion outline paired with a mixed brilliant facet arrangement promotes both internal brilliancy and broad flashes of color. From the crown view the table presents a concentrated core of deep blue, while the mixed cut facets toward the girdle return bright scintillation and controlled dispersion. The moderate depth of 3.66 mm supports a pleasing balance between faceup size and light performance, avoiding the overly dark appearance often seen in deeper stones. In hand or set, the stone displays excellent window control, maintaining rich color even under daylight conditions, and the very slightly included clarity grade will be nearly invisible once the gem is set. The combination of vivid color and excellent polish makes the stone responsive to a variety of lighting environments, producing both intense saturated color and lively sparkle depending on viewing angle and light quality.

For a custom jewellery piece the sapphire responds well to pairing with white diamonds, which will accentuate the vivid blue and provide a classic, restrained contrast. A clean round brilliant diamond halo will increase perceived faceup size while preserving the sapphire as the focal point, or a tapered baguette shoulder arrangement will add architectural emphasis for a refined ring profile. For a contemporary aesthetic consider pairing with small brilliant cut white sapphires or low profile melee diamonds set in a platinum or 18 karat white gold mount, where the cool metal tone reinforces the stone color. For a more colorful palette, pairing with warm or analogous stones can add depth and interest, for example fine pink sapphires along a ring shank will introduce a subtle floral warmth, while small green tsavorite garnets or emerald accents create a complementary contrast that intensifies the sapphire blue. Alternate metal choices such as 18 karat yellow gold or rose gold will shift the visual temperature, producing either a vintage inspired look with yellow gold, or a softer romantic contrast with rose gold, depending on the desired character of the finished piece.

When commissioning a custom setting from The Natural Sapphire Company clients receive both the provenance and the lapidary details needed to make informed design choices, and the untreated status of this Ceylon sapphire is a defining characteristic to be preserved in the finished piece. Our design consultations consider finger size, setting profile, and everyday wearability to determine prong versus bezel options, and to advise on accent stone sizes and placements that will best complement the cushion outline and mixed brilliant cut. Care recommendations include gentle cleaning with mild soapy water and a soft brush, avoidance of harsh chemicals and extreme thermal shock, and periodic inspection of the mount to ensure secure settings. For clients interested in certification and documentation we can provide detailed imagery and reports, and facilitate in person or virtual previews of proposed settings to ensure the finished jewellery meets aesthetic and practical expectations.
