1.10 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.10 carat heart shape yellow sapphire, with dimensions 5.98 x 6.62 x 3.83 mm, is presented by The Natural Sapphire Company. This stone has been fashioned in a refined heart outline that preserves optimal weight from the rough while providing a pleasing silhouette for solitaire and cluster work. The mixed brilliant cut employed here combines a step influenced pavilion with a brilliant oriented crown, a deliberate choice to maximize return of light from a relatively shallow profile and to enhance scintillation at everyday viewing distances. Clarity is graded very slightly included, evaluated at eye level, which in practice indicates minimal internal features that do not interfere with the overall transparency and light transmission. Color intensity is classified as intense, giving the sapphire a saturated yellow that reads vividly in both natural and artificial light, and the gem has an excellent polish that reinforces edge definition and facet crispness. Enhancement is heat treated, a stable and widely accepted process, and provenance is Ceylon Sri Lanka, a source historically associated with clean material and bright, lively color.

The cutting details speak to technical precision and an understanding of sapphire material behavior. The mixed brilliant design incorporates a pavilion geometry where a controlled pavilion depth near 3.83 mm supports a broad table and a carefully faceted crown, yielding an interplay between broad flashes and fine scintillation. Facet junctions are aligned to preserve heart symmetry, with a distinct cleft at the apex executed to maintain visual balance across the lobes. The cutter has emphasized pavilion main facets that direct light back through the crown in measured proportions, rather than dispersing it sideways, a decision that favors brightness and perceived size. The crown facet angles have been calibrated to the specific refractive index of corundum, optimizing the critical angle response for maximum return of spectral dispersion within a yellow field, and the girdle has been finished to a thin to medium profile to ease bezel or prong setting while protecting against chipping. The excellent polish produces mirror like facet planes that reduce surface scattering, so light is managed primarily by internal reflection and facet geometry, resulting in lively movement and an even face up appearance.

Color and clarity are central to the gemology of this piece, and both attributes have been treated with measured assessment. The yellow hue is intense rather than pastel, showing strong saturation with a pure primary yellow component and minimal secondary modifying tones, which is typical of select Ceylon material where iron related chromophores yield clear, vivid yellow color. Because the stone is transparent, color concentration is apparent through the table and across facet planes, producing a stable visual color that does not shift markedly with viewing angle, a desirable trait for colored stones intended for everyday wear. The very slightly included clarity grade, evaluated at eye level, indicates that inclusions are present but small and generally not obtrusive to unaided observation, and they have been positioned by the cutter to minimize impact on brilliance and to avoid stress concentration points. Heat treatment has been applied in a controlled manner, a practice with a long history in Sri Lankan sapphires, to enhance color uniformity and reduce the visibility of certain internal features, while maintaining the integrity and durability of the corundum lattice. The result is a stone that balances natural character with optimized aesthetics, conforming to expectations of connoisseurs who seek both origin and enhancement transparency.

Heritage and traditional use inform the desirability and setting choices for this heart shape yellow sapphire. In South Asian gem culture, Ceylon yellow sapphires have been prized for auspiciousness and for their association with prosperity and clear minded focus, often used in talismanic and ceremonial jewelry across generations. The heart shape, though more modern in commercial practice than classical cuts, echoes the long standing tradition of personal devotion stones, and its bilateral symmetry translates well into settings that reflect both romantic and traditional symbolism. For durability and to respect the gemological proportions, this sapphire responds well to low profile prong settings that secure the lobes and apex, or to a bezel that reinforces the girdle without obscuring the crown and table, taking advantage of the excellent polish to display facet crispness. From a craft perspective, mounting this 1.10 carat heart in warm metals will complement the intense yellow tone, while cooler metals will create a visual contrast that emphasizes clarity and brilliance. At The Natural Sapphire Company we present this heart shaped Ceylon yellow sapphire as an item that combines precise cutting technique, documented origin, and thoughtful enhancement, a piece that speaks to collectors who value technical refinement, gemological honesty, and a connection to the traditional uses of colored sapphire in fine jewelry.
