2.06 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent heart shape blue sapphire from Ceylon, weighing 2.06 carats, measures 8.08 x 8.96 x 3.81 mm, and presents a mixed brilliant cut with an excellent polish. The clarity has been graded as very slightly included when evaluated at eye level, and the color intensity is categorized as dark. The piece is heat treated, a standard enhancement that stabilizes and deepens the blue tone typical of Sri Lankan material. The heart outline displays well formed lobes and a distinct cleft, with the length to width balance yielding a pleasing, symmetric silhouette. The moderate pavilion depth of 3.81 mm relative to the length and width produces an approximate depth ratio in the mid forties percent range, a proportion that supports saturated hue retention without collapsing light return. These objective details are provided to allow a precise assessment of performance and suitability for various mounting styles, and they reflect The Natural Sapphire Company commitment to transparent, technically informed presentation.

The mixed brilliant faceting strategy has been executed to optimize the interplay between color saturation and dynamic light return. On this heart, the cutter has combined a predominantly brilliant crown with pavilion facet geometry that moderates internal reflections, producing a balance of broad color face up and lively scintillation. The crown facet arrangement directs incident light into controlled internal reflections, while a careful pavilion faceting scheme allows for selective light leakage that prevents a washed out appearance in a stone of dark intensity. This is particularly important in Ceylon blue sapphires, where maintaining velvety saturation while permitting flashes of white and blue reflective return is essential. The heart outline necessitates precise symmetry across the vertical axis, and the facet junctions at the lobes and cleft have been aligned to minimize light starvation zones. The excellent polish across table, crown, girdle, and pavilion facets reduces micro abrasion and surface scattering, thereby preserving specular highlights and crisp facet contrast that enhance both brilliance and contrast patterning when viewed under direct and diffuse light.

Color and clarity interact with the cut to define the gemological character of this sapphire. The dark color intensity absorbs a greater proportion of the visible spectrum, so facet angles and table proportions have been selected to favor selective internal reflection rather than wide dispersion. The mixed brilliant approach concentrates return light into larger flashes, which read as saturated blue rather than pale or overly bright white flashes, making the face up appearance consistently deep and evenly toned. The very slightly included clarity grade indicates minor internal features that do not disrupt the general transparency, and these are often rendered inconspicuous by judicious facet placement. Heat treatment has been applied to enhance color uniformity and to reduce the visual impact of microscopic rutile or silk inclusions, a customary and stable enhancement for Ceylon sapphires. For setability, The Natural Sapphire Company recommends settings that allow controlled light ingress to the pavilion, such as low prong or partial bezel frameworks, which maintain the silhouette and heart geometry while permitting the facet architecture to perform optimally. In a pendant or solitaire ring where the girdle sits unobstructed and the pavilion receives light from behind and the sides, the engineered balance of crown brilliance and pavilion retention will produce a rich, deep blue presence that reads as both luxurious and technically refined.
