4.84 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

This 4.84 carat oval greenish blue sapphire measures 10.91 x 8.86 x 6.22 mm and is faceted in a mixed brilliant configuration to maximize light return while preserving weight. The mixed brilliant pavilion with a faceted crown produces a lively interplay of scintillation and broad flash, compensating for a slightly included clarity grade when evaluated at eye level. Color was graded as vivid, with a primary blue hue shifted toward green under certain lighting, indicating modest pleochroism typical of Sri Lankan material. The excellent polish enhances surface luster and facet contrast, while the controlled heat treatment is standard practice to homogenize tone and improve saturation without compromising structural integrity. Proportionally the stone presents a medium to medium deep tone, which allows the vivid saturation to read as lively rather than inky, and the oval outline provides broad table area for color presentation and efficient face up spread.

Comparatively this Ceylon sapphire differs from classic Kashmir material which typically exhibits a velvety cornflower blue with a softer, more diffuse light scattering and a slightly colder blue without green overtone. Against fine Burmese sapphires this stone is marginally lighter and greener, Burmese stones tending toward a purer, more intense royal blue at similar saturation. Compared with Thai and Australian sapphires this gem is noticeably brighter and less inky, those localities frequently producing darker, more green dominant tones with heavier body color. Madagascar sapphires can approach the brightness and clarity of Sri Lankan gems, however this specific stone’s greenish blue hue and vivid intensity are characteristic of premium Ceylon material, offering a lively, Mediterranean blue rather than the deep nocturnal blue seen in some other sources. At The Natural Sapphire Company we recommend settings that allow light access to the pavilion, such as four prong or semi bezel mounts, to maximize the mixed brilliant cut geometry and showcase the vivid greenish blue face up color while accommodating the stone’s slight inclusions.
