0.59 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.59 carat round blue sapphire measures 5.19 x 5.19 x 2.90 mm, and it is presented in a mixed brilliant cut designed to balance face up spread with internal light return. The mixed brilliant cut combines a round brilliant crown with a faceted pavilion that preserves weight while optimizing scintillation, and this configuration contributes to an apparent presence that is larger than the carat weight alone might suggest. Clarity has been assessed as eye clean at eye level, indicating that no inclusions are visible to the naked eye under normal viewing conditions, a quality that enhances both the apparent purity of tone and the transmission of light through the stone. Color intensity is categorized as medium light, a tonal range typical of Ceylon sapphires that yields a delicate and luminous blue, and the sapphire displays an excellent polish, with crisp facet junctions and a smooth polished surface that supports lively reflections. This sapphire originates from Ceylon Sri Lanka, and it has received no enhancement, meaning the color and clarity are natural and untreated, attributes that are often valued by collectors and those seeking unmodified gemstones.

The combination of size and clarity makes this sapphire particularly well suited for a statement piece, because the 5.19 mm diameter offers a clear and substantial face up area, and the eye clean clarity ensures that the stone reads clean and vivid without the need for masking by additional diamonds or heavy settings. In practice a 0.59 carat round sapphire of this dimension will present a defined presence at the center of a solitaire ring, a pendant, or a single stone setting, and the mixed brilliant cut enhances scintillation so that the stone captures attention through movement and changes in light. The medium light color intensity provides versatility, as it retains a recognizable blue hue while remaining luminous and soft enough to coordinate with both white metals and warm metals, and because no enhancements were applied the color grades are the result of the material itself rather than treatment. The excellent polish contributes directly to the sapphire s ability to reflect and refract light, and the absence of visible inclusions allows for uninterrupted light paths that maximize brilliance and sparkle, two visual qualities important for any piece intended to make a measured yet unmistakable statement.

From a practical and design perspective this sapphire s specific measurements and attributes provide clear guidance for setting and fabrication, because a 5.19 mm round stone with a 2.90 mm depth will fit standard mounting dimensions commonly used for classic solitaire and halo styles, and jewelers can rely on the mixed brilliant pavilion to maintain a balanced table to depth ratio when designing for optimal light performance. The corundum species to which sapphire belongs rates 9 on the Mohs hardness scale, a fact that reinforces its suitability for daily wear in rings and other frequently worn jewelry, and the eye clean clarity reduces the need for protective settings intended to conceal weaknesses, allowing greater flexibility in choosing open prong or low bezel designs that showcase the cut and color. The provenance from Ceylon Sri Lanka provides context for the color character, as sapphires from this region are known for clear, bright tones that sit comfortably in the medium light range, and the lack of enhancement simplifies both appraisal and long term care considerations since no special handling is required to preserve an applied treatment.

The Natural Sapphire Company documentation accompanies this sapphire, providing record of origin enhancement status weight and measured dimensions, and supporting accurate evaluation and integration into bespoke jewelry designs. For clients and designers seeking a natural untreated Ceylon sapphire that offers a strong visual presence without relying on size alone this 0.59 carat round mixed brilliant cut stone presents a precise combination of face up spread clarity and finish that together create an elegant and reliable center gemstone. The measured proportions and excellent polish make it straightforward to design a mounting that emphasizes the stone s natural attributes, and the eye clean clarity ensures that its color and cut are read cleanly at a distance and at close inspection.
