3.08 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This stunning transparent 3.08 carat cushion shape blue sapphire from Ceylon, Sri Lanka, measures 9.82 by 7.60 by 4.05 mm, and combines a mixed brilliant cut with an excellent polish to deliver exceptional light performance. The vivid color intensity and eye level very slightly included clarity allow strong, saturated blue flashes without the cloudiness that can dull lesser stones. Compared with typical blue spinels and blue topazes, which tend to have lower refractive indices and therefore softer reflections, this Ceylon sapphire returns light with a more energetic, gemlike brilliance. Against tanzanite, which shows pronounced pleochroism and can appear very different from one angle to another, this sapphire offers a steadier, more reliable blue that maintains vibrancy under varied lighting. Even among other sapphires, the mixed brilliant pavilion in this cushion shape enhances scintillation and contrast more effectively than broad step cuts, producing lively mirrorlike flashes that emphasize color depth while preserving clean white light return.

The Natural Sapphire Company presents this heat treated, finely finished gem as an excellent value for collectors and designers who prioritize superior reflective qualities and lasting wear. The high quality polish amplifies facet crispness, so when compared to rougher or poorly polished stones the sparkle reads as both sharper and more controlled. Because corundum is a nine on the Mohs scale, this sapphire also sustains its reflective surface with far less risk of abrasion than softer alternatives, which helps maintain its initial brilliance over years of wear. Heat treatment is a standard and widely accepted enhancement that intensifies the vivid Ceylon blue without compromising transparency, making this sapphire a more consistent performer than untreated stones with uneven color patches. For clients choosing between comparable gems, this Ceylon cushion sapphire from The Natural Sapphire Company offers a rare combination of vivid hue, precise facet architecture, and durable high polish, delivering superior reflectivity, resale value, and visual impact when set into fine jewelry.
