5.03 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional 5.03 carat cushion shape blue sapphire measures 9.55 x 7.58 x 6.96 mm, and combines classic proportions with a modern mixed brilliant cut to maximize both depth and scintillation. The stone is transparent with a vivid color intensity, and presents a rich, lively Ceylon blue that is characteristic of Sri Lankan material. Clarity is graded very slightly included evaluated at eye level, meaning the gem is remarkably clean to natural sight and any inclusions are minor and do not detract from the overall visual impact. The polish is excellent, producing sharp facet junctions and lively return of light, while the mixed brilliant facet arrangement balances broad flashes with sparkling pinfire, making this sapphire both vibrant in color and dynamic on the finger. Enhancement is heat treated, a stable and widely accepted process in the trade that enhances color without compromising the gem structure, and the origin is Ceylon Sri Lanka, a source renowned for producing sapphires with both beautiful saturation and excellent clarity.
