2.19 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This 2.19 carat pear shape color change sapphire presents precise lapidary refinement and measurable optical performance, supplied by The Natural Sapphire Company. The stone measures 11.85 by 6.53 by 3.74 millimeters, yielding a length to width ratio of approximately 1.82 and an overall depth near 41 percent when calculated against the average girdle diameter, proportions that favor a balanced elongated silhouette and optimized light return. The mixed brilliant cut pairs a full brilliant crown, with well defined kite and star facets, to a carefully faceted pavilion that combines modified facets to control the light path, creating a fine balance between broad flash and scintillation. The clarity grade is very very slightly included, evaluated at eye level, and the material is transparent, allowing unobstructed internal reflection. Polish is graded excellent, and the sapphire is heat treated to stabilize and intensify color, consistent with responsible enhancement practices for Ceylon origin material.

The optical character of this Ceylon color change sapphire is defined by its internal structure and facet geometry, producing a sparkle that is technically distinctive and visually compelling. Corundum refractive properties at higher index values concentrate light within the gem, while the mixed brilliant faceting maximizes total internal reflection and contrast, producing rapid scintillation across the pear outline. The crown facet arrangement captures incident light and delivers it to the pavilion geometry, where repeated internal reflections and precise facet junctions return light as discrete flashes and broad color pulses, rather than a uniform wash. The color change behavior is a function of trace element absorption and pleochroic effects in the crystal, the result is a perceptible hue shift between lighting environments, with dominant violet blue and subtle purple shifts under different sources, intensifying the visual depth of each flash. Small, well positioned inclusions sit below the level of the pavilion facets and act to enhance localized light dispersion without materially diminishing transparency. The combination of intense color intensity, exacting facet symmetry, and excellent polish produces a lively, three dimensional scintillation and color play, making this pear shape sapphire an exceptional choice for a high quality center stone or bespoke setting.
