2.17 Ct. Pinkish Purple Sapphire from Ceylon (Sri Lanka)

This offering from The Natural Sapphire Company is a transparent heart shape sapphire weighing 2.17 carats, with precise dimensions of 6.96 x 7.78 x 4.88 mm, cut in a mixed brilliant style. The gem exhibits a pinkish purple hue with vivid color intensity, a clarity grade of very slightly included evaluated at eye level, and an excellent polish. Enhancement status is none, the stone is untreated, and the documented origin is Ceylon Sri Lanka. These baseline specifications establish the piece as a collector grade fancy sapphire, where weight, proportions, and natural color combine to support both visual impact and technical merit.

The geometric faceting scheme has been explicitly designed to maximize light play, employing a mixed brilliant approach that balances a faceted crown geometry with a modified pavilion layout. On the crown the cutter has executed a pattern of kite and triangular facets arranged around a proportionally sized table, producing high contrast facet junctions that function as controlled light engines. The pavilion uses a combination of tapered facets and shallow step elements, creating internal reflectors that redirect light back through the crown rather than allowing it to leak through the girdle, this balancing act reduces windowing and amplifies scintillation when the stone is set. The heart outline is symmetric with well defined lobes and a crisp cleft, allowing the facet geometry to read consistently across the outline, and the facet junctions are tight, indicating precise lap work and consistent facet angles. The cutter tuned the facet angles to suit corundum refractive indices in the range of 1.760 to 1.768, optimizing total internal reflection for corundum and ensuring that dispersion and return brilliance are maximized for this weight and geometry.

Color performance is a defining attribute of this sapphire, the pinkish purple hue reads as a balanced admixture of magenta and violet tones with vivid saturation that remains even across the table and pavilion. Pleochroic behavior is present, with the stone revealing slightly different tonal emphases when rotated under directional light, often shifting between warmer pinkish tones and cooler violet notes, this phenomenon adds perceived depth and dynamic color movement. The very slightly included clarity grade indicates inclusions are present but limited in size and position, evaluated at eye level they do not materially disrupt the light path or the overall optical performance, and they serve as natural signatures that confirm the stone is untreated. The excellent polish contributes to crisp mirror facets, minimal surface diffusion, and clean facet junctions, all of which preserve the designed light return pattern, this level of finish reduces veil or haze that can otherwise soften contrast and diminish scintillation.

From a setting and wear perspective the stone benefits from its balanced proportions and heart outline, its modest table size and controlled pavilion depth provide consistent return both in tension and prong mounts. The dimensions make the stone highly suitable for ring designs where the heart profile is a focal point, and the mixed brilliant faceting will animate in typical indoor and outdoor lighting conditions, producing strong pin point scintillation and field dispersion under spot light, and a broad, even glow in diffuse light. For maximum light performance a setting that exposes the pavilion to light ingress is recommended, such as a four prong head that secures the lobes and allows the cleft to remain visible, alternatively a low bezel with open gallery will protect the girdle while permitting light circulation. The Natural Sapphire Company can advise on specific metal choices that complement the pinkish purple hue, warmer metals will enhance the pink component, while white metals will emphasize the violet character, final choices depend on design intent and wearer preference. This heart shape, untreated Ceylon sapphire represents a technically refined stone, with geometric faceting engineered for optimum light play, and with natural color and clarity attributes that will satisfy discerning buyers and collectors.
