1.53 Ct. Pink Sapphire from Ceylon (Sri Lanka)

This specimen is a transparent pink sapphire weighing 1.53 carats, fashioned into a pear shape with precise dimensions of 8.97 by 5.90 by 3.65 millimeters. The pavilion and crown are executed in a mixed brilliant cut, combining the scintillation advantages of brilliant faceting with the depth and color retention of step elements. Clarity is assessed as very slightly included at eye level, indicating minor internal features that do not impede visual performance. Color presents as medium intense pink, a saturation that permits lively light return while maintaining the stones distinct hue. The polish is graded excellent, and the gem shows no enhancement, its natural character and lattice integrity preserved. The origin is Ceylon Sri Lanka, a source renowned for sapphires with lively tone and natural vibrancy. This description and assessment are provided by The Natural Sapphire Company, reflecting the precise attributes and gemological observations that define this piece.

The sapphires structural and optical characteristics underpin its exceptional sparkle. At the mineralogical level this sapphire is corundum, a trigonal crystal system with a compact atomic arrangement that yields a refractive index appreciably higher than many common gemstones. That higher refractive index governs the degree to which light is bent and internally reflected as it passes through the stone, and when paired with a meticulous mixed brilliant cut, it produces pronounced brilliance and scintillation. The mixed brilliant approach uses a brilliant faceted crown to create numerous small, well defined facet junctions that act as multiple micro mirrors, reflecting direct and scattered light back to the viewer. Meanwhile the pavilion incorporates controlled step like facets that guide light back through the crown in coherent pathways rather than allowing diffuse leakage. The pear outline itself contributes to how light is distributed, the tapered end concentrating return and the wider shoulder offering broad flashes, producing a dynamic interplay of bright flashes and pointed scintillation as the gem or the wearer moves. Excellent facet symmetry and tight junctions, combined with the sapphires transparency, maximize the number of internal reflections before light exits, so that each interaction with a facet surface enhances perceived brightness. Minor inclusions graded as very slightly included can further animate the sparkle by creating subtle points of contrast, small bright centers against the pink field, without materially diminishing clarity or light return.

Cut proportions, polish quality, and the stones natural, untreated state all converge to produce a balance of brilliance and color that distinguishes this sapphire. The dimensions of 8.97 by 5.90 by 3.65 millimeters and the overall table and depth relationships favor efficient light return, avoiding an overly deep pavilion that would trap light, or a shallow profile that would allow light to escape. Excellent polish ensures that facet surfaces are free from milling lines or pitting that scatter light, maintaining sharp reflections and crisp facet edges. The medium intense color saturation is particularly important for perceived sparkle, because while very deep saturation can mute surface brightness by absorbing a portion of returning light, a medium intense tone allows both color presence and lively reflection to coexist. The absence of enhancement means the internal structure remains in its natural state, preserving the native interplay between inclusions, crystal growth zoning, and facet geometry, which together yield a sparkle that reads as authentic and natural. Origin from Ceylon Sri Lanka adds a context of provenance, as sapphires from this region are historically associated with vibrant hues and well balanced optical properties. Taken together these factors make this 1.53 carat pear shape pink sapphire a gem whose scintillation and brilliance arise from both inherent material properties and exacting lapidary execution, qualities that The Natural Sapphire Company documents and presents for precise evaluation and informed selection.
