3.09 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 3.09 carat cushion shape blue sapphire from Ceylon Sri Lanka combines classical proportions with contemporary cutting, presenting dimensions of 9.11 x 6.78 x 5.71 mm and a mixed brilliant cut. The mixed brilliant facet arrangement balances broad table and crown facets with a more faceted pavilion, producing both broad flashes of color and lively scintillation. The stone has an intense color intensity and excellent polish, and it has not undergone any enhancement. Clarity is graded as slightly included when evaluated at eye level, which is consistent with natural material from notable Ceylon sources and contributes to the gem's natural character without compromising transparency or overall performance. The Natural Sapphire Company presents this piece with full disclosure of origin treatment and visual attributes.

Under different lighting conditions this sapphire displays distinct and attractive behaviors that a buyer should expect. In strong natural daylight and diffuse northern light the intense blue reads richly saturated with a slightly vivid tone, and the mixed brilliant cut produces broad flashes that allow the color to read evenly across the table. In direct sunlight the stone shows increased contrast between bright reflective facets and deeper blue windows, creating a lively display of brilliance and localized color saturation. Under warm incandescent lighting the stone shifts toward a warmer blue with subtle violet undertones, and the excellent polish enhances reflectivity so that the face up appearance remains bright. Under modern LED lighting the stone often appears very crisp, with pinpoint scintillation from the brilliant facets and a strong impression of depth from the pavilion. In low and candlelight the sapphire retains presence through its color saturation, with softer flashes and a more velvety blue tone that emphasizes body color over sparkle. When rotated the sapphire will show a modest degree of pleochroism typical of corundum, moving between slightly different blue nuances as light enters along different crystallographic directions, and the mixed cut helps to display these shifts as both color and brightness changes rather than abrupt zoning.

Practical considerations for setting and presentation are informed by the stone dimensions and the way it interacts with light. At 9.11 x 6.78 mm and 3.09 carat this cushion form offers a strong face up presence suitable for a prominent ring setting, a pendant, or an eye catching cocktail piece. An open or partially open setting will allow optimal light transmission and will showcase the sapphire in daylight and in artificial light sources, while a closed back setting will emphasize the saturated face up color and can mute some backlighting effects. Choosing a metal color will influence perceived color balance, with white metals tending to highlight the stone s brightness and cooler tones, and warmer metals adding subtle warmth to the visible color. The slightly included clarity grade means that the stone benefits from careful orientation in the setting to present the cleanest face up window to the viewer, and the excellent polish ensures that reflections remain crisp and focused. This sapphire embodies the natural qualities collectors and designers seek from Ceylon material, and The Natural Sapphire Company documents its origin, weight, dimensions, cut, clarity, polish, color intensity, and lack of enhancement to allow informed selection and responsible design integration.
