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

This 1.72 carat cushion shape sapphire presents a refined balance between measured dimensions and intense color expression. With a face length of 7.07 millimeters, a width of 5.45 millimeters, and a pavilion depth of 4.73 millimeters, the stone exhibits a face up presence that is both elegant and concentrated. The pinkish purple hue is classified with intense color intensity, giving a saturated but lively appearance that reads distinctly pink at some angles and distinctly purple at others. The mixed brilliant cutting style is well chosen for this material, combining the broad, scintillating facets of a brilliant system with the softer cushion outline to emphasize both flashes of white light and vivid color. This sapphire is transparent and finished to an excellent polish, allowing internal light transmission to occur with minimal surface diffusion, and the gem carries a disclosed enhancement of heat treatment, a stable and commonly accepted practice for intensifying tone and improving clarity in sapphire material from Sri Lanka.

From a faceting and optical performance perspective, the mixed brilliant execution on this cushion sapphire is engineered to maximize both brilliance and color saturation. The mixed brilliant arrangement typically pairs a brilliant crown with a modified pavilion architecture that incorporates narrower pavilion facets to retain color while providing dynamic scintillation. In this example, the interaction between the crown facet array and the pavilion facet planes creates a strong contrast pattern and plentiful pinpoint sparkle, while larger flashes are delivered by the broader table and bezel facets. The depth to average diameter ratio for this stone is approximately 76 percent, a deliberate choice that favors weight retention and color saturation over extreme face up spread. That slightly deeper pavilion enhances the gem's ability to display its intense pinkish purple hue under varied lighting environments. The facet junctions are crisp and the polish exceptional, which reduces stray light leakage and increases the efficiency of internal reflection, delivering vivid color and high return of light from every viewing angle.

Clarity is a critical factor for the optical purity of colored gemstones, and this sapphire is graded very very slightly included when evaluated at eye level, indicating only minute inclusions that do not affect the gem s transparency or brilliance to the naked eye. Under magnification these inclusions are subtle, and because they are minimal and well positioned, they do not disrupt the colour flow or produce windowing effects. The material s transparency and the excellent polish work together to maintain an undisturbed light path through the pavilion, which allows for strong dispersion and lively scintillation. The disclosed heat treatment has been applied to enhance the gem s inherent color and to reduce the visibility of minor inclusions, a stable and accepted treatment when fully disclosed. Originating from Ceylon, Sri Lanka, this sapphire carries the characteristic lively tone and saturation that Sri Lankan material is known for, with trace element chemistry that favours pink to violet hues, thereby giving this gem its distinctive pinkish purple character.

The combination of precise cutting, superior polish, and VVS clarity contributes to the sapphire s flawless optical performance from every angle, a quality that is immediately perceptible in hand and in finished jewelry. The mixed brilliant cut provides both broad, luminous flashes and concentrated scintillation, so the gem performs beautifully whether set as a solitaire or within a halo configuration. For mounting recommendations that preserve and accentuate the stone s light return, consider open prong settings that allow light to enter the pavilion and reflect back through the crown, or low bezel settings with an open gallery to avoid darkening the pavilion. The dimensions make this an ideal candidate for a center stone in a refined engagement ring, or a statement ring where the intense pinkish purple color is the focal point. At The Natural Sapphire Company we present this 1.72 carat Ceylon sapphire with clear disclosure of its treatment and origin, and with attention to the technical attributes that matter to knowledgeable buyers. The result is a gem where craftsmanship and material quality combine to enhance its beauty from every angle, offering enduring visual impact and technical excellence for fine jewelry applications.
