1.52 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.52 carat cushion shape blue sapphire from The Natural Sapphire Company presents a refined balance of weight, proportion, and visual presence. At 1.52 carats the stone sits in a size category that delivers measurable presence in a mounting without overwhelming a ring head or pendant setting, providing an ideal compromise between everyday wearability and noticeable impact. The carat weight is a defining characteristic of this gem, informing not only its market value but also the way light is captured and returned through the pavilion and crown. In this example the 1.52 carat weight has been used judiciously by the cutter to maintain a pleasing table diameter and depth profile, resulting in a stone that reads as both substantial and elegant when set. The Natural Sapphire Company presents this sapphire as an example of premium quality where carat weight is matched to cutting proportions, clarity, and color to deliver an integrated gem of enduring appeal.

The stone measures 6.41 by 6.38 by 4.44 millimeters, a near square cushion outline with gently rounded corners and balanced pavilion depth that contributes to its transparency and scintillation. The mixed brilliant cut employed here combines the broad facets of a step crown with the radiant facet arrangement of a brilliant pavilion, optimizing both color saturation and brilliance. Clarity is graded as very slightly included, evaluated at eye level, which indicates minor inclusions that do not materially affect the stone's transparency or overall visual performance under normal viewing conditions. The sapphire is transparent, allowing light to traverse the girdle and return through the crown facets, and the polish is rated excellent, creating crisp facet junctions and minimal surface disturbance. Enhancement is heat treated, a stable and widely accepted practice in sapphire finishing that improves tone and clarity while remaining permanent under normal wear conditions.

Origin is Ceylon, Sri Lanka, a source with a long history of producing high quality blue sapphires with lively and nuanced color. This particular stone exhibits an intense color intensity, with saturation and tone that read as vivid and pure blue in neutral illumination conditions, while still maintaining enough depth to display velvety live areas under varied light. The cushion shape, combined with the mixed brilliant cut, helps to distribute that intense color evenly across the table, avoiding the windowing or overly dark zones that can occur when weight is retained at the expense of optical proportions. At 1.52 carats, the combination of intense color and disciplined cutting yields a gem that conveys premium quality visually, because the carat weight supports a face up presence large enough to appreciate the color depth, while the facet architecture maintains brilliance and life.

From a practical perspective this 1.52 carat Ceylon sapphire is suitable for a wide range of fine jewelry applications, including solitaire rings, halo settings, and bespoke designs where proportion and color are key considerations. The dimensions allow for secure bezel or prong settings, and the very slightly included clarity grade supports close setting options without risk of obscuring the face up beauty. Care for heat treated sapphires follows standard gemological guidance, avoiding harsh chemicals and extreme temperature shocks, and routine professional cleaning will preserve the excellent polish and facet crispness. The carat weight, coupled with origin, cut, clarity, and polish, positions this stone within The Natural Sapphire Company collection as a premium quality example of Ceylon blue sapphire, suitable for clients seeking a balanced combination of presence, optical performance, and historical provenance.
