0.36 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This oval sapphire is a technically refined gemstone from The Natural Sapphire Company, weighing 0.36 carat and measuring 5.70 x 3.65 x 2.05 mm. It is transparent with a faint color intensity and a clarity graded as very very slightly included when evaluated at eye level. The cutter employed a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a more geometric pavilion, to optimize both scintillation and light return in a small oval format. The overall depth of 2.05 mm represents approximately 44 percent of the average diameter, a deliberately shallow proportion that lightens the face up and enhances apparent size. The finish displays excellent polish, and the material has been heat treated to stabilize and gently enhance hue and tone. The piece is sourced from Ceylon, Sri Lanka, an origin known for producing sapphires with delicate cornflower to pastel blue tones.

Under varied lighting conditions this sapphire performs predictably according to its cut geometry and faint color. In cool daylight, the stone reads as a soft, icy blue with even color distribution, because the shallow depth and mixed brilliant faceting favor broad white light return and minimal color saturation, producing a clean, crystalline presence. Under strong directional LED or halogen spot lighting, the brilliant crown facets generate crisp, return flashes and lively pinpoint scintillation, while the step influenced pavilion provides contrast lines that accentuate movement and create a pattern of bright and dark facet flashes. In warm incandescent lighting the faint blue will appear subtler, often taking on a slightly warmer or near neutral cast, yet the excellent polish maintains significant white brilliance so the gem remains lively on the finger. When worn, the oval silhouette and precise faceting deliver a steady combination of broad flash and fine scintillation, offering an apparent size and sparkle that outperform its modest carat weight.

For buyers seeking a technically sound small sapphire with considered cutting decisions and verified origin, this Ceylon blue from The Natural Sapphire Company presents a calibrated balance of light performance, color subtlety, and craftsmanship. Heat treatment is disclosed, and the stone is well suited to settings that maximize table exposure to maintain its bright face up presence.
