0.28 Ct. Greenish Yellow Sapphire from Ceylon (Sri Lanka)

This gem is a transparent, round shape sapphire weighing 0.28 carat, with precise dimensions of 4.23 x 4.20 x 2.28 mm, cut as a mixed brilliant cut to optimize both scintillation and light return, with meticulous facet junctions that balance a faceted crown and a pavilion designed to deliver focused brilliance. The mixed brilliant strategy places smaller star and kite facets on the crown, paired with a more pavilion oriented brilliant configuration that enhances return of light through the table, producing an even pattern of pinpoint flashes and larger broad flashes when the stone is tilted. The cut exhibits excellent polish, which preserves crisp facet definition and maximizes contrast, and the girdle proportions maintain secure mounting potential while preserving optimal optical performance. Clarity evaluation at eye level is very very slightly included evaluated at eye level, indicating inclusions are extremely minor and do not interrupt the visual performance when mounted, and under magnification these internal features are minor needle or silk structures that do not compromise durability or brilliance.

Color description is technically specific, this example sits in the greenish yellow range with a medium light color intensity, a balance that yields both freshness and presence without veering into muddy or overly dark tones. The hue shows a primary yellow body with a subtle green shift, a characteristic that can be influenced by trace element composition and crystal lattice substitution common to Ceylon provenance, and the result is a lively, sunlit tone that responds to changing light environments with pleasing variation. Because the stone is not enhancement treated, the hue and saturation are entirely natural, offering the kind of untreated character valued by connoisseurs who require provenance and natural color integrity, and the untreated status also means color stability is an intrinsic property of this material. In this size and intensity range the greenish yellow color is particularly effective for settings where contrast is desired, the medium light intensity allows the stone to read as vibrant against both warm and cool metal tones, and the mixed brilliant faceting enhances both internal reflection and the perception of color saturation by creating dynamic light interplay across the pavilion and crown facets.

From a proportion and setting perspective this sapphire offers excellent versatility, the 2.28 mm depth in relation to the average diameter corresponds to a depth proportion of approximately 54 percent, a proportion range that supports a pleasing face up appearance without compromising light performance. The near perfect round outline and balanced spread give it a larger perceived diameter for the carat weight, making it ideal as a delicate solitaire accent, a halo center for a lightweight engagement or fashion ring, or a refined stud or pendant where precise color harmony is required. The mixed brilliant cut ensures strong scintillation under movement, an attribute that complements prong mountings that allow maximum light entry, while a bezel mount can emphasize the vivid greenish yellow tone by providing a reflective metal frame that intensifies contrast. For designers who prefer color contrast, pairing this sapphire with rose gold will warm the yellow component and accentuate a golden glow, while white gold or platinum will present the greenish component more crisply, and for those seeking maximum perceived size it performs exceptionally well set within a delicate halo of small white diamonds which will enhance perceived brightness without overwhelming the natural hue.

Provenance and craftsmanship are integral to the value of this stone, it originates from Ceylon Sri Lanka, a source historically noted for producing sapphires with elegant, nuanced color profiles and good crystal quality, and this specimen demonstrates those characteristics with natural hue, stable tone, and clearly executed faceting. The absence of enhancement treatment underscores its appeal to discerning buyers who prioritize natural material and documented origin, and the excellent polish and mixed brilliant design reflect careful lapidary control to preserve both durability and optical performance. At The Natural Sapphire Company we evaluate each stone for exacting standards of cut, clarity, color, and origin to provide full transparency, and this greenish yellow round sapphire represents a refined option for clients seeking a compact, vibrant, and technically optimized gem for bespoke jewelry applications.
