4.02 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 4.02 carat cushion shape blue sapphire from Ceylon Sri Lanka represents a rare balance of size, color, and clarity that sets it apart from many stones on the market, and The Natural Sapphire Company takes pride in presenting it to conscious collectors. Measuring 9.27 by 8.27 by 6.13 millimeters, the gem offers a true presence as a center stone while remaining versatile for a variety of settings, and its mixed brilliant cut is engineered to maximize scintillation and depth, outperforming flatter or poorly proportioned cuts that can look lifeless in hand. The sapphire is transparent with vivid color intensity and an excellent polish, qualities that make it immediately striking in daylight and under evening lighting, and its clarity is described as very very slightly included when evaluated at eye level, which means the stone reads as clean to the eye and delivers visual purity that higher inclusion levels simply cannot match. Heat treatment has been applied to bring out the best in the color and stability of the stone, a widely accepted enhancement in the industry that when fully disclosed provides consistent beauty and long term durability, and compared to untreated stones that may be uneven in tone, this sapphire offers a reliably vivid and appealing blue that commands more immediate wearability and confidence in daily jewelry use.

Beyond its intrinsic gemological strengths, this sapphire is positioned for the conscious consumer who values provenance and ethical practice as much as optical excellence, and The Natural Sapphire Company maintains strict sourcing standards that differentiate our supply chain from anonymous market sources. We work with trusted partners in Sri Lanka to ensure traceability, transparency, and responsible mining practices, and our full disclosure policy means you receive clear information about origin and enhancement, allowing you to make an informed acquisition that aligns with ethical priorities. For collectors who compare options, this stone offers superior value when measured against similar carat weight sapphires that are either poorly cut, heavily included, or of uncertain origin, and its combination of eye clean clarity, vivid Ceylon blue saturation, and excellent polish yields a piece that will integrate seamlessly into a considered collection or become the centerpiece of a bespoke commission. If you are choosing a sapphire that reflects both beauty and conscience, this Ceylon cushion is an excellent expression of that commitment.
