1.52 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

One transparent yellow sapphire, weighing 1.52 carats, presents a heart shape that balances presence and wearability for bespoke jewelry projects. The gem measures 5.71 by 6.72 by 4.91 millimeters, dimensions that translate into a visible and elegant face up appearance while maintaining proportions conducive to secure mounting. Cut to a mixed brilliant faceting scheme, the pavilion and crown work together to maximize light return and scintillation, and the finish is described as excellent polish. Clarity has been evaluated as very slightly included at eye level, a grade that preserves visual purity while confirming natural character. Color is reported as vivid in intensity, a saturation that yields a lively and unmistakable yellow without veering into overly dark tones. The sapphire originates from Ceylon Sri Lanka, and the stone has been heat treated, a standard and stable enhancement that intensifies hue and improves clarity in many natural sapphires.

The heart shape itself is a versatile and technically specific form, one that requires careful symmetry and well defined lobes to translate neatly into finished jewellery. At the stated dimensions this heart maintains a balanced length to width relationship, which is particularly important for directional designs where orientation affects the overall look. The mixed brilliant cut combines facets intended to enhance brilliance with larger facets that emphasize color, which in a vivid yellow sapphire delivers both lively sparkle and uniform color distribution. The depth of 4.91 millimeters supports a well proportioned pavilion that contributes to optical performance, reducing the risk of light leakage that can dull appearance. With very slight inclusions visible only at eye level, the stone retains an attractive window free of obvious crystals or feathers, providing confidence for open settings where the pavilion may be visible.

For custom jewellery design this 1.52 carat heart shape sapphire offers multiple practical advantages. The size is sufficient to serve as a memorable centre stone in engagement rings and pendants, while remaining compact enough for refined daily wear. The geometry is suited to three prong or five prong settings where secure claw engagement preserves the heart silhouette, and to bezel settings where metal can be shaped to follow the cleft and lobes for extra protection. The mixed brilliant faceting provides predictable light return in ring settings under variable lighting, and the vivid yellow works well against both warm and cool metals, including 18 karat yellow gold for tone on tone harmony, 18 karat white gold or platinum to emphasise contrast, and rose gold for a contemporary warm white pairing. Designers may also use this heart as a focal point within a halo of smaller stones to amplify visual impact, or as a solitary emblem in a pendant where the shape already communicates intent without additional ornamentation.

Provenance and treatment are important in custom work where documentation informs appraisal and long term care. This sapphire from Ceylon Sri Lanka carries the geological signature associated with Sri Lankan deposits known for producing saturated yellow material, and the heat treatment noted is a conventional practice that stabilises and enhances colour and clarity. The Natural Sapphire Company provides gem information and imagery to support design decisions, including measured dimensions and visual grading observations, which assists bench jewellers in calculating prong placement and seat depth. Given the stone characteristics, recommended setting tolerances should account for the 4.91 millimeter depth and the face proportions to avoid overhanging edges or excessive bezel walls that could obscure the heart motif. In summary, this heart shape yellow sapphire combines a desirable carat weight, precise dimensions, intentional cutting, and a vivid natural hue, attributes that make it an ideal candidate for considered custom jewellery commissions where both aesthetic and technical requirements are equally important.
