2.10 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes a single transparent 2.10 carat round blue sapphire from Ceylon, presented by The Natural Sapphire Company. The gem measures 7.91 by 7.83 by 4.80 millimeters, and is cut in a mixed brilliant style to balance table luster with pavilion scintillation. Clarity is graded as very slightly included when viewed at eye level, indicating minor internal features that do not materially detract from the face up appearance. Color intensity is classified as medium, the hue is blue with a faint cool violet influence, the polish is excellent, and the stone has been heat treated, a stable and commonly accepted enhancement for sapphires.

Optically this sapphire displays a bright, clear face up presence, with a medium tone that produces a lively, slightly satiny blue. The mixed brilliant cut supports strong return of light through the table, creating a balanced play of bright flashes and smaller scintillating facets. With the clarity grade reported as very slightly included at eye level, the stone reads effectively eye clean in standard viewing conditions, and the excellent polish contributes to crisp facet junctions and a clean window free of surface disturbance. The combination of transparency, medium color intensity, and precise cutting yields a modern, vibrant blue that photographs well and sits with pleasing visual proportions in common mounting sizes.

Compared to sapphires from other classic sources, this Ceylon gem shows the lighter, more luminous blue that Sri Lankan material is known for, rather than the deeper, more velvety tones associated with Kashmir origin stones. Kashmir sapphires typically present a richer, silkier cornflower blue with a softer, more diffuse light return, while this Ceylon example is brighter and more transparent, with crisper facet definition. Burmese sapphire examples can show stronger saturation and a warmer, more intense royal blue hue, whereas this Ceylon stone maintains a cooler, slightly violet leaning blue at a medium tone. Madagascar stones occupy a broad range, sometimes mirroring Sri Lankan brightness and sometimes tending toward stronger saturation or a slight greenish component, depending on the deposit. Montana sapphires characteristically shift toward teal or greenish blue and often have a lighter tone, which is a distinct contrast to the purer blue hue observed here. Thai and Cambodian material often exhibits a darker, inky blue with heavier tone, which accentuates depth over brilliance, again differing from the lively, medium toned character of this Ceylon sapphire.

From a practical and design perspective, this 2.10 carat round mixed brilliant blue sapphire functions well in settings that allow light access to the pavilion, such as open prong or semi bezel designs, where the cut can maximize return and scintillation. The medium color intensity and excellent polish give flexibility for white or yellow metal mounting, and the eye level clarity grade means the stone will appear clean to typical observers while retaining natural internal character under magnification. The heat treatment reported is a widely accepted enhancement that stabilizes and improves color, and it does not compromise routine wear when set and cared for appropriately.
