1.64 Ct. Pink Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.64 carat heart shape pink sapphire with dimensions of 7.10 x 7.68 x 4.30 mm, originates from Ceylon Sri Lanka, and represents a premium, investment quality gem. At 1.64 carats this heart shaped sapphire occupies a rarity tier where size, shape, and natural color converge to command premium value per carat, the carat weight translating directly into a more substantial face up presence and stronger light interaction. The measured depth of 4.30 mm against the average diameter of 7.39 mm yields a depth proportion of approximately 58 percent, a proportion that supports balanced color saturation and efficient light return, producing an intense color intensity while preserving transparency. The clarity grade is slightly included, evaluated at eye level, indicating minor internal characteristics that do not materially disrupt overall transparency and that in practice serve as confirmation of natural origin, rather than detracting from visual appeal. No enhancement has been applied, the color and clarity are natural, and this untreated provenance is an important attribute for discerning buyers seeking authenticity and long term value.

The cutting style is faceted, executed as a mixed brilliant cut that pairs a faceted crown of brilliant style facets with a pavilion treatment optimized for color concentration and scintillation. This mixed brilliant approach enhances both fire and brilliance, while the heart outline has been cut with careful symmetry and clean facet junctions, resulting in an excellent polish and crisp facet planes that maximize light return and minimize windowing. The precise balance of crown angle, pavilion depth, and table proportion has been tailored to this material to emphasize the intense pink hue while maintaining strong brilliance, a characteristic only achievable through meticulous lapidary craftsmanship. As presented by The Natural Sapphire Company this piece is offered with the technical pedigree that experienced collectors and gem professionals expect, including documented origin and treatment status. For clients who require detailed imaging, facet diagrams, or official gemological certification, professional assistance is available to support appraisal and setting decisions, ensuring that the 1.64 carat heart shape pink sapphire delivers both aesthetic distinction and technical excellence.
