0.70 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent 0.70 carat radiant shape greenish blue gem, with exact dimensions of 5.43 x 4.83 x 2.44 mm, presented by The Natural Sapphire Company. The stone displays a classic radiant cut, combining the dispersed brilliance of a modified brilliant facet set on the crown with the linear emphasis of step style facets on the pavilion. The faceting grid has been executed to maximize both face up spread and optical return, with crisp facet junctions and well proportioned crown angles that preserve color saturation while permitting lively scintillation. The dimensions and weight place this sapphire in a category that reads larger than its carat alone might suggest when set, due to an optimized table to depth relationship and efficient light transmission through the pavilion. The finish is of a superior standard, with an excellent polish that produces clean facet reflections, minimal external abrasion, and tight girdle treatment, supporting long term wear and retaining the integrity of the faceted planes.

Color and clarity characterize the specimen with a technical clarity that will satisfy discerning connoisseurs. The hue is dominantly blue with a pronounced greenish component, creating a unique cool teal zone that remains vivid and legible under a broad range of lighting conditions, described here as intense in overall color intensity. Saturation is strong, providing a richly colored face up appearance without veiling, and the interplay between hue and tone yields depth that reads well in both direct and diffused light. Clarity is graded as very slightly included when evaluated at eye level, indicating that inclusions are minimal, localized, and do not materially interrupt light transmission or the perception of transparency. Under loupe inspection the inclusions present as discrete points and minor internal features that are typical of natural corundum from Ceylon, and they contribute to the gemological fingerprint of the stone rather than detract from its visual performance. Importantly this sapphire is natural and unenhanced, no heat treatment or other enhancement has been applied, preserving the original growth features and color zoning that provide assurance of natural origin from Ceylon Sri Lanka.

The radiant cut geometry of this 0.70 carat piece lends itself to statement jewelry that demands clarity of color and purity of cut. The radiated crown facets disperse light into lively white and colored flashes, while the pavilion faceting has been oriented to control return and prevent unwanted leakage, producing a crisp, lively face up appearance. The compact footprint with a slightly rectangular outline makes it versatile for both solitaire and halo designs, where the stone will command attention through its intense color and transparent body. At the given dimensions the gem is large enough to serve as a focal point in a ring head without appearing delicate, yet compact enough for secure bezel or prong mounting. Precision cutting and the excellent polish work together to magnify the perceived size and presence, since well executed facet planes increase the effective spread and brightness, factors that are critical when designing a piece intended to read as a statement item.

Provenance and workmanship combine to make this sapphire a refined selection for collectors and designers who prioritize natural color and meticulous cutting. Origin Ceylon Sri Lanka is associated with a particular type of blue green tonality and crystalline clarity, and this example reflects those regional tendencies while offering an intense and saturated hue in an unenhanced state. For practical considerations the inherent toughness of corundum makes it suitable for daily wear in a ring or the pendant center of a substantial neckpiece, and the very slightly included clarity ensures that under normal wear the stone will maintain its visual purity. At The Natural Sapphire Company we present this radiant 0.70 carat greenish blue sapphire with confidence in its technical attributes, recommending settings that allow the table and crown to interact with light for maximal color display, such as low profile four prong heads or fine micro pave halos that accentuate the stone without overpowering its natural characteristics.
