0.55 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional Ceylon blue sapphire represents a rare marriage of size and color that is increasingly difficult to find, especially among stones under one carat. Weighing 0.55 carat, and measuring 4.54 x 4.56 x 3.56 mm, this round, faceted gem carries an uncommon depth for its dimensions, offering a presence on the finger that outperforms many larger, less concentrated stones. Cut in a mixed brilliant style, the pavilion and crown facets have been balanced to maximize scintillation and color return, giving the sapphire a lively play of light while maintaining a velvety, mid tone blue that is true to its Ceylon origin. At eye level the stone is eye clean, free of visible inclusions, and its excellent polish ensures each facet edge catches light with a crisp, elegant flash. Heat enhancement has been applied historically to refine hue and clarity, a widely accepted and stable treatment that reveals the sapphire at its best, while the medium color intensity offers rare versatility, showing vivid saturation without tipping into the darker, more common inky blues that dominate small stones.
