1.30 Ct. Purple Sapphire from Ceylon (Sri Lanka)

One transparent 1.30 carat purple sapphire, cut in a classical emerald shape, presents a measured geometry and provenance that will interest discerning buyers. The table faces 7.84 by 4.82 by 3.33 millimeters, producing a length to width ratio of approximately 1.63, and a depth of 3.33 millimeters that corresponds to roughly 52.6 percent of the average girdle diameter. The cut is an emerald style, with long, parallel step facets defining the crown and pavilion planes, a restrained table that emphasizes directionality of light, and crisp facet junctions whose symmetry is consistent across all octagonal corners. Clarity is graded as very very slightly included, evaluated at eye level, meaning that inclusions are minute and do not interrupt overall transparency under normal viewing, and the polish is excellent, which minimizes surface scattering and preserves clean light transmission. This sapphire is untreated, with no enhancement, and carries an origin of Ceylon, which contributes to its particular violet leaning within the sapphire family, a hue that the cutter has preserved through careful orientation of the rough during the faceting process, presented here by The Natural Sapphire Company.

The geometric philosophy behind the faceting strategy prioritizes controlled light movement over scintillation, an approach particularly effective with step cuts. The emerald cut used in this stone employs a series of broad, planar facets that act as light corridors, producing elongated flashes rather than point source sparkle. When light enters the table it is guided by parallel crown steps into the pavilion steps, where internal reflection is maximized along the length of the stone, creating the characteristic hall of mirrors effect. The length to width ratio of 1.63 enhances this directional return, offering sustained linear flashes along the axis, while the depth at 52.6 percent supports sufficient refractive travel to allow those flashes to develop without significant leakage through the girdle. The excellent polish and precise facet alignment are crucial here, because any deviation at the facet junctions would break the continuity of the light corridors and create dark areas or washed out flashes. The cutter has maintained strict parallelism across opposing facets and consistent facet angles, which together produce a controlled but lively optical performance that will be immediately apparent in both studio light and daylight.

Color performance and internal clarity operate in tandem to define this sapphires perceived brightness and saturation, and each of these parameters has been calibrated through cutting decisions. The stone exhibits a light color intensity, a nuance that allows for delicate violet tones rather than a heavy saturated purple, and the transparency is such that color is carried through the length of the stone rather than being localized near the table. Sapphire crystals can display pleochroism, and in purple and violet material selective orientation during rough planning preserves the most attractive body color when viewed through the table. In an emerald cut, the large table and elongated steps reduce the number of truncated facets that would break up color, so the observed hue remains coherent across the face of the gem. The very very slightly included clarity grade indicates inclusions are minimal and positioned so as not to establish major windows or dark mirrors that would interrupt the step facet light flow. Because this sapphire is not heat treated or otherwise enhanced, the color and inclusion characteristics are natural to the Ceylon origin, providing an authentic optical signature and stable long term color behavior.

From a practical gemological and setting perspective the dimensions and cutting choices offer multiple design advantages that a jeweler or client can exploit. The elongated emerald proportions at 7.84 by 4.82 millimeters make this piece particularly well suited to classic solitaire rings where the linear light play can follow the finger, and to east west settings where the long axis is used to create an understated, modern silhouette. The moderate depth of 3.33 millimeters keeps the stone low enough for protective settings and comfortable daily wear, while still maintaining the necessary internal geometry for strong light return. Because the faceting creates long flashes rather than dispersed scintillation, settings that expose the crown and allow light to enter through the table, such as four prong, bezel with elevated gallery, or tension mounts, will best showcase the hall of mirrors effect. The precision polish and absence of enhancements mean that polishing wear and routine maintenance will preserve the original optical behavior, and routine professional cleaning will restore the full crispness of the step facet reflections. For buyers seeking a technically refined purple sapphire with transparent body, controlled geometric faceting, and verifiable Ceylon origin, this stone represents a balanced confluence of material quality and cut mastery, presented confidently by The Natural Sapphire Company, and available for consultation on custom settings or certification details.
