1.61 Ct. Blue Sapphire from Ceylon (Sri Lanka)

Long before this sapphire ever touched a jeweler’s bench, it lived as a secret inside the ancient rocks of Ceylon, Sri Lanka, a place celebrated for stones of luminous character and storied heritage. Rain and rivers labored for millennia to free these crystals from their host rock, washing them into gem gravels where miners, working with both tradition and care, recovered each piece by hand. This particular stone traveled that same path, carried from the earth by experienced hands and sent to our workshops with the provenance and respect it deserves. The story of a gemstone is not merely geological, it is cultural and human, and at The Natural Sapphire Company we treat each sapphire as a living heirloom, tracing its origin to Ceylon, Sri Lanka and preserving the memory of the land in which it was born.

When you look closely at this cushion shaped blue sapphire you will see the careful decisions that bring its personality forward, it weighs 1.61 carat, and measures 6.80 x 5.68 x 4.63 mm, a size that balances presence with everyday practicality. The mixed brilliant cut was chosen to maximize blue flashes and scintillation, and the excellent polish ensures each facet returns light to the eye with crisp clarity. Color reads as medium intense, a lively blue that balances saturation with brightness so it reads beautifully under both daylight and indoor lighting. The clarity is slightly included evaluated at eye level, which means it maintains a transparent, open appearance while still displaying natural character, the small inclusions are part of the stone’s fingerprint and affirm its natural origin. The sapphire has been heat treated, a stable and widely accepted enhancement that refines color and clarity while respecting the gem’s natural structure.

Beyond beauty, there is practical strength, this sapphire is a corundum, rated 9 on the Mohs hardness scale, second only to diamond, and that inherent hardness makes it exceptionally resistant to scratches and abrasions that everyday jewelry encounters. For this reason a 1.61 carat cushion sapphire of these proportions makes an excellent candidate for daily wear pieces, from an engagement ring that endures a lifetime of gestures, to a pendant you will find yourself reaching for every morning. Because the clarity is slightly included evaluated at eye level, we recommend secure settings that protect the girdle and corners, such as four or six prongs with slightly thicker shoulders, or a protective bezel setting that preserves the cushion silhouette while minimizing exposure to knocks. The excellent polish and mixed brilliant cut also mean the stone will retain impressive sparkle even when set low, and the stability of heat treatment ensures color permanence in normal wear.

If you imagine this sapphire in a finished piece, think of an heirloom in miniature, a blue that carries the tropics of Ceylon and the patience of skilled cutters, placed to live beside your skin and collect the light of your life. The Natural Sapphire Company stands behind this gem with the experience to advise on settings that emphasize both safety and style, we can recommend metals and mounting styles that complement the medium intense blue while sheltering the stone, and we can create bespoke settings that honor the cushion shape and mixed brilliant cut. Caring for this sapphire is simple, gentle cleaning with warm soapy water and a soft brush will keep it bright, avoid harsh abrasive cleaners and extreme thermal shock, and routine inspection of the setting will ensure the stone remains secure. For someone seeking a transparent, vibrant, and durable sapphire that tells a story from Ceylon, Sri Lanka to your jewelry box, this 1.61 carat cushion blue sapphire combines provenance, workmanship, and everyday resilience into a single, wearable treasure.
