1.08 Ct. Bluish Grey Star Sapphire from Ceylon (Sri Lanka)

One beautiful translucent 1.08 carat oval shape bluish grey star sapphire is presented with precise dimensions of 7.06 by 5.04 by 2.82 mm, cabochon cut, slightly included clarity as evaluated at eye level, light color intensity, and an excellent polish. The cabochon finish has been executed to reveal a clear and sharp asterism that crosses the gem face, producing a distinct star effect that responds predictably to changes in light and orientation. This sapphire is natural, with no enhancement, and its origin is Ceylon, Sri Lanka, a source noted for fine star sapphires and consistent crystalline quality. Color is described as bluish grey, a versatile tonal range that is at once subdued and evocative, allowing the star to remain the defining optical feature. The combination of translucency and cabochon curvature yields a gentle glow from within, while the excellent polish enhances surface lustre and ensures that the six ray star is clean and well defined under direct illumination.

The oval shape and the gem proportions make this 1.08 carat star sapphire particularly well suited to custom jewellery projects, where the balance of size and profile is an important design consideration. At approximately seven by five millimetres in face dimensions, the stone is large enough to function as a confident solitaire in rings and pendants, while remaining compact for design schemes that require subtlety. The low dome height of 2.82 mm offers designers predictable bezel wall profiles and comfortable ring ergonomics when set as a finger gem, and the elongated oval footprint facilitates a range of orientation choices for designers who wish to align the star axis with a finger or with the central axis of a pendant. For bespoke earrings or for use as a central accent in multi stone compositions, the measured weight and planar dimensions allow for matched visual proportions without overwhelming complementary elements. The slight inclusions described at eye level are typical for asteriated sapphires, and they serve as natural markers that do not detract from the star when the gem is properly oriented and securely set.

Design and setting considerations for this cabochon star sapphire should focus on maximising the visual prominence of the star, preserving the cabochon contour, and protecting the stone in day to day wear. Bezel settings offer a secure framing option that follows the oval outline, and a thin polished bezel wall will allow the star to read well while providing significant edge protection. Prong settings remain viable when prongs are positioned away from the central axis of the asterism so as not to interrupt the star lines, and a low profile gallery will help light to enter the stone from above and below, enhancing contrast. Open back settings may be used selectively to increase transmitted light and to warm the tone of the bluish grey body when paired with suitable metal backing, while closed back mounting can stabilise the appearance under different lighting conditions. Metal selection should respond to the light color intensity and the desired overall aesthetic, white metals such as platinum or white gold will emphasise the cool bluish grey nuance and the white star, while warm metals such as yellow or rose gold will create a softer contrast and a more vintage expression. Accent stones in near colourless white diamonds or small pale sapphires will lift the face of the piece and frame the star without competing with it.

The Natural Sapphire Company can support the customisation process with practical recommendations on proportions, setting styles, and metal pairings that will best showcase the unique optical properties of this star sapphire. Our approach focuses on measurements and technical fit, advising on bezel lip heights, prong thickness, and seat geometry to preserve durability and to maintain the star as the central visual attribute. Because this sapphire is untreated, its provenance from Ceylon, Sri Lanka, and its natural asterism are important selling points for clients seeking authenticity and rarity in a bespoke piece. Routine care is straightforward, with cleaning limited to warm water and a soft brush, avoiding heat and harsh chemicals, and periodic inspection of settings to confirm that the cabochon remains secure. For designers and clients interested in exploring mounting options, we can provide CAD mock ups and setting templates that reflect the exact dimensions of 7.06 by 5.04 by 2.82 mm, and we can recommend complementary stone sizes and shapes for side stones or halo treatments. This 1.08 carat oval cabochon star sapphire combines natural charisma with measured proportions, making it an exceptional choice for a considered one of a kind jewellery commission.
