3.10 Ct. Blue Sapphire from Ceylon (Sri Lanka)

A rare and arresting example of natural beauty, this transparent 3.10 carat oval blue sapphire is a gem for collectors who understand the value of authenticity and provenance. Sourced from Ceylon, a region synonymous with some of the finest blue sapphires on earth, this stone measures 10.06 x 7.99 x 4.71 mm, presenting a perfect balance between presence and wearable elegance. Cut to a mixed brilliant pattern, the stone combines the scintillating fire of brilliant facets with the depth enhancing qualities of a traditional pavilion, resulting in a profile that is both lively and composed. Graded as eye clean at standard viewing distance, with an intense color intensity and an excellent polish, this sapphire is entirely natural and untreated, an increasingly rare attribute in today’s market. At The Natural Sapphire Company we curate only the most exceptional examples, and this sapphire is an invitation to own an authentic piece of Ceylon heritage, a gemstone that embodies scarcity, refinement, and enduring value.

Viewed face up the oval outline and mixed brilliant faceting create a dynamic interplay of light and shade, offering a window into the stone that is both lively and profound. The intense blue saturates the pavilion and crown, while excellent polish ensures that each facet edge is crisp and mirror like, directing light with precision. From above the gem shows a broad, velvety blue field punctuated by bright flashes where the brilliant facets catch the eye, giving the appearance of depth without heaviness. The balance of proportions preserves both table size and pavilion depth, allowing the pavilion facets to reflect a deep reservoir of color while the crown facets return scintillation and lively pinpoint flashes. Because the sapphire is transparent and eye clean, it communicates clarity and purity, characteristics prized by connoisseurs, and when set in a bespoke mounting the stone reads as purposeful and singular, a piece designed not for the masses but for an individual with discerning taste.

Lighting reveals the many personalities of this Ceylon sapphire, transforming it subtly yet unmistakably as the environment changes. In cool natural daylight the stone opens to a sky influenced cornflower blue, a luminous and vivid hue that seems to radiate from within, the mixed brilliant facets producing crisp scintillation and a lively play of blue tones. Under warm incandescent or candlelight the sapphire takes on a deeper, more velvety character, the intense saturation leaning toward a rich royal blue with soft flashes of brighter blue where the crown facets capture the light. In modern LED or jewelry display lighting the stone exhibits strong contrast and lively sparkle, the pavilion reflections producing pinpoint flashes that accentuate the cut geometry, while in lower ambient light it maintains presence, showing a plush, saturated blue that reads as sophisticated and substantial. Direct sunlight will provoke the strongest transitions, with brilliant flashes and a dazzling interplay of light across the mixed brilliant facets, while shaded or indirect light invites the gem to show its inner depth and pure color intensity. Throughout all conditions the excellent polish ensures smooth reflections and maximum return of light, and because the sapphire is untreated the color is wholly natural, evolving with the light rather than appearing artificially stable or muted.

Owning this 3.10 carat Ceylon sapphire is to join an exclusive circle of collectors and patrons who seek authenticity, rarity, and timeless beauty. Whether you envisage this gem at the center of an heirloom engagement ring, a bespoke pendant, or a private collection cabinet, its dimensions and mixed brilliant cut offer flexibility for a range of elegant settings while maintaining the singular presence that such a stone deserves. At The Natural Sapphire Company we present this sapphire as a limited opportunity, a natural, untreated gem of intense color and flawless polish that will not be replicated easily. For the buyer who values provenance, the stone’s Ceylon origin speaks to a storied tradition of sapphire excellence, and its eye clean clarity ensures that the viewer’s focus is on color and light rather than on inclusions or enhancements.
