3.51 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire’s story begins beneath the tropical soils of Ceylon, where ancient geological forces concentrated aluminum and traces of iron and titanium into corundum over millions of years. From one of Sri Lanka’s celebrated alluvial deposits we selected a transparent crystal that, when examined at the rough stage, showed the promise of deep, even color and excellent crystal integrity. At The Natural Sapphire Company we trace each step of a gem’s journey, and this 3.51 carat cushion shaped sapphire carries that lineage in every facet. Its dimensions, 8.95 by 6.54 by 5.63 millimeters, give it a presence that reads both substantial and refined when set. The cutter worked to preserve weight while transforming the rough into a mixed brilliant cut, a choice that balances scintillation with the deep, velvety body color so prized in fine Ceylon sapphires. The result is an eye-clean gem, evaluated at eye level, with vivid color intensity and an excellent polish that allows light to dance through the pavilion and crown in a display of luminous blue that changes subtly with movement.

The physical craftsmanship is part technical, part art. The cushion shape brings a gentle, classic silhouette that flatters many mounting styles, while the mixed brilliant facet arrangement brings crisp fire across the table and crown, and broad, saturated flashes from the pavilion. This cutting approach was chosen deliberately to emphasize the sapphire’s vivid, saturated blue while preserving depth and avoiding light leakage. An excellent polish ensures mirrorlike facet junctions, giving the stone a luxurious finish and crisp reflections. We disclose that this sapphire has been heat treated, the most common and stable enhancement used in the industry to deepen color and improve clarity. Heat treatment, applied responsibly, intensifies the blue and is considered permanent under normal wear. At The Natural Sapphire Company we provide full details about treatments and origin, and we are happy to advise on settings that protect and complement this stone, whether you envision it as a classic solitaire, a halo engagement ring, or an elegant pendant.

Beyond its physical beauty, this Ceylon sapphire carries a long history of meaning and metaphysical associations that many collectors and wearers value. Historically prized by royalty and clergy, blue sapphires have been associated with wisdom, nobility, and divine favor across cultures. Today, many people wear sapphires to foster mental clarity, to support calm focus during stressful times, and to encourage truthful expression. This gem is traditionally linked to the throat chakra, and is believed to help with clear communication and the articulation of intention. It is also associated with inner vision and insight, making it a favorite for those seeking to quiet mental chatter and access contemplative stillness. While these properties are spiritual and symbolic rather than medical, sapphire’s enduring reputation as a stone of protection and clarity lends a quiet confidence to any piece of jewelry that features this vivid Ceylon blue example.

Wearing and caring for this sapphire is simple, and thoughtful care will keep it radiant for generations. Because sapphire is second only to diamond in hardness among commonly used gemstones, it withstands daily wear beautifully when set securely. For routine cleaning, use warm soapy water and a soft brush to remove everyday oils, and avoid harsh chemicals and ultrasonic cleaning if the mounting contains fragile settings or other treatments. When commissioning a setting through The Natural Sapphire Company, consider protective designs such as bezel edges or prongs that are balanced to show the cushion shape while guarding the stone’s corners. This particular sapphire, with its transparent character, vivid color, and eye-clean clarity, becomes more than a gem— it becomes a companion for milestones, a symbol in a family heirloom, and a piece of Sri Lankan geology and craftsmanship you carry forward.
