8.53 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for the perfect stone to mark a milestone, whether that is the ideal engagement ring to symbolize a lifelong promise or a rare specimen to add to a serious collection, you want certainty, provenance, and beauty. This C.Dunaigre certified blue sapphire from Ceylon answers those needs with quiet authority. At 8.53 carats and cut into a generous cushion shape measuring 12.43 by 10.16 by 6.36 mm, this gem offers presence without overwhelming the wearer. The mixed brilliant cut was chosen to balance scintillation and broad flash, giving the stone life in both candlelit evenings and sunlit days. Clarity was evaluated at eye level and found to be eye clean, which means the gaze meets an unclouded depth and clarity from the first look. The color presents as medium light intensity blue, a hue that is distinctly Ceylon in character, floral and lively rather than overly dark. The polish is excellent, ensuring that each facet returns light precisely, and critically this sapphire is natural and untreated, with no enhancement, a trait confirmed by the C.Dunaigre certificate that accompanies the gem.

The journey of this sapphire began in the storied soils of Sri Lanka, where miners with generations of knowledge unearth sapphires from alluvial gravels and vein deposits. The rough crystal that would become this cushion sapphire was identified early on as exceptional for clarity and color, and it was set aside for careful work rather than mass processing. From the mine the crystal was taken to the local sorting rooms where experienced gem sorters evaluated weight, shape potential, and color zoning. It then passed to a master cutter who considered how to best reveal the stone's inner fire. The mixed brilliant treatment was selected to marry the broad, velvety color windows typical of Ceylon sapphire with the lively sparkle that collectors and those seeking a showstopping ring desire. During cutting the cutter paid particular attention to pavilion angles and table size to preserve weight while maximizing brilliance. After cutting and polishing the sapphire was examined under multiple lighting conditions, measured precisely, and evaluated at eye level for clarity. The result is an 8.53 carat, transparent sapphire that reads both refined and natural, with clean facets and a finish that magnifies its blue personality. The C.Dunaigre certificate documents weight, cut, dimensions, clarity assessment, color intensity, no enhancement, and origin, providing the reassurance collectors and buyers require.
