1.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shaped blue sapphire weighs 1.40 carats, a weight that positions it firmly within the premium range for gemstones of this type, offering a balance of presence and wearability. The significance of carat weight extends beyond simple mass, it directly influences the stone's visual impact, setting possibilities, and perceived value. At 1.40 carats this sapphire provides a substantial face up area while remaining practical for a range of ring and pendant designs, delivering a presence on the finger that reads as elegant and refined without overwhelming the wearers hand. The weight, combined with the gemological attributes of color, clarity, and cut, makes this sapphire a compelling example of premium quality, suited to clients who value both aesthetic appeal and enduring value.

The gem presents with precise dimensions of 7.16 by 5.21 by 3.66 millimeters, and a cushion shape that enhances the stone's deep blue character while preserving a comfortable profile for everyday wear. The mixed brilliant cut maximizes light return through a combination of step and brilliant facet geometries, creating scintillation as well as depth, and the excellent polish produces crisp facet junctions and clean reflections. Clarity is graded very slightly included, evaluated at eye level, reflecting minimal internal characteristics that do not materially detract from brilliance or transparency. The color is classified as intense, a rich and well saturated blue that displays even tone across the table, and the sapphire has been heat treated, an established and accepted enhancement method used to enhance color and clarity while maintaining the integrity and stability of the gem.

Visually this sapphire exhibits a strong combination of color saturation and facet performance, with the mixed brilliant architecture producing a lively interplay of flashes and broad color planes. The 1.40 carat weight contributes to a desirable table size, allowing the intense blue hue to register clearly in both direct and diffused lighting conditions, and the cushion outline provides a classic silhouette that complements both modern and vintage inspired settings. Given the dimensions and depth percentage informed by the measurements, the gem offers a pleasing profile on the finger, with enough depth to retain color without appearing dark when set, and enough spread to show presence in smaller mounting styles. Jewelry designers can rely on this stone to anchor a piece with a strong focal point, while clients benefit from a stone that reads as substantial in carat weight, yet comfortable for daily wear.
