0.66 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite transparent blue sapphire carries within it the long lineage of Ceylon gem lore, a jewel that speaks to centuries of regal taste and enduring craftsmanship. We present a single 0.66 carat round sapphire, measuring 5.02 by 4.98 by 3.36 mm, fashioned in a mixed brilliant cut that balances old world charm with modern brilliance, offering a vivid color intensity and an eye clean clarity grade when viewed at eye level, polished to an excellent finish. Originating from Ceylon Sri Lanka and thoughtfully heat treated to optimize its tone and clarity, this gem embodies the timeless blue that has long been associated with royalty, piety, and fidelity. The deep yet lively blue flashes with internal life under every light, a reminder of oceanic depths and storied mine workings, and its compact size makes it an ideal heart stone for a piece meant to be cherished across generations. At The Natural Sapphire Company we honor that legacy by ensuring each stone’s provenance and cutting are treated with the reverence they deserve.

Envisioned in a custom setting this sapphire offers elegant versatility and harmonious contrast when paired with complementary stones, perfect for a vintage inspired cluster, an understated solitaire with side accents, or an heirloom style three stone ring. A pavé halo of small, F to G color round brilliant diamonds would amplify the sapphire’s vivid blue, creating a luminous frame that lifts the center hue, while tapered baguette diamonds along a platinum band would lend architectural refinement and a distinctly classical air. For a warmer palette, small yellow sapphires or subtle champagne diamonds set in rose gold would introduce a nostalgic glow that recalls antique jewelry, while a pair of delicate pear shaped white sapphires or drop pearls flanking the center could transform it into a romantic pendant echoing Victorian sensibilities. For truly bold contrast, two narrow baguette emeralds on either side would call forth a regal triad, the blue anchoring the composition with depth and the green adding aristocratic flourish. Whatever the design, The Natural Sapphire Company can advise on proportions and metal choices to ensure the 0.66 carat Ceylon sapphire sits perfectly balanced, preserving its voice within a piece that will feel at once ancient and eternally modern.
