1.24 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.24 carat cushion shape blue sapphire from The Natural Sapphire Company is a finely proportioned and visually arresting gem, with dimensions of 6.69 x 4.76 x 4.14 mm, a mixed brilliant cut, and an excellent polish. The sapphire displays vivid color intensity that reads as a deep, pure blue under natural and artificial light, and it has been evaluated as very slightly included at eye level, which means it reads as eye clean to most observers while retaining natural character. The stone was heat treated to optimize color saturation and clarity, a stable and widely accepted enhancement for corundum, and its documented origin is Ceylon Sri Lanka, a region with a long standing reputation for producing some of the world most desirable blue sapphires. Taken together, the weight, cut, polish, clarity and origin make this sapphire a balanced and rare offering that appeals to the discerning buyer who values both aesthetics and geological provenance.

For an educated buyer who considers gemological factors as part of value, several attributes of this stone are particularly meaningful. The mixed brilliant cut in a cushion outline combines the depth and rounded corners of a cushion shape with the facet arrangement that maximizes scintillation and return of light, which enhances the perceived size and liveliness of the gem. The very slightly included clarity grade evaluated at eye level indicates minimal internal features, which typically do not detract from the gemesthetic appeal while providing assurance that the stone is natural and not overly compromised by filling treatments. The vivid color intensity is a primary driver of desirability in blue sapphire, and Ceylon Sri Lanka origin carries historical and market recognition for producing blue hues that range from cornflower to vivid saturated blue, often with a luminous, velvety character. The excellent polish ensures that facet junctions are sharp and smooth, supporting brilliance and making the stone an excellent candidate for fine jewelry.

This sapphire is exceptionally adaptable for customization into a wide variety of settings, and The Natural Sapphire Company can work with you to design a setting that complements the gemological attributes of the stone. For a classic and enduring look, a four prong or six prong solitaire ring in platinum or 18 karat white gold will present the cushion profile and brilliant scintillation with a modern and elegant silhouette. For additional presence, a single row halo of small round brilliant diamonds will increase apparent size and add contrast, while a double halo can create a vintage inspired statement. For a warmer aesthetic, 18 karat yellow gold offers a striking color contrast that emphasizes the blue saturation, and rose gold imparts a contemporary and feminine warmth. Bezel settings provide maximum protection for the cushion corners and are ideal for active wearers, while cathedral or knife edge profiles elevate the gem for more finger presence. Alternative couture options include east west orientation to emphasize the length dimension, three stone configurations to pair the sapphire with tapered baguettes or trapezoids, cluster settings for a floral motif, and asymmetric custom designs that incorporate mixed metals and accent sapphires for color grading effects.

Practical considerations and design advice for mounting this sapphire focus on balancing protection, light performance and visual harmony. Because the stone is heat treated and stable under normal conditions, routine wear is safe when standard care recommendations are followed, and it will perform well in the majority of setting styles. If your intent is an engagement ring or daily wear item, consider a low bezel or four prong setting with protective gallery and secure mounting, which preserves the cushion form while minimizing risk to the corners. For maximum brilliance and color play, open prong settings or partial bezels that allow light to enter through the pavilion will enhance depth and scintillation. Accent choices such as diamond pavé shanks or small side sapphires can be used to create contrast or tone on tone effects, and careful selection of accent stone color temperature will either warm or cool the overall appearance. The Natural Sapphire Company offers bespoke design consultations, CAD renderings and recommended metal choices based on the desired final outcome, and we provide gemological documentation and care notes so that you can commission a setting with full confidence in both the aesthetic and the technical compatibility of the design.
