3.98 Ct. Blue Cabochon Sapphire from Burma (Myanmar)

If you are searching for a truly exceptional blue sapphire that ends the quest for rarity, beauty, and provenance, this gem answers that need. Many clients come to The Natural Sapphire Company looking for an engagement stone that feels both timeless and unique, or for a collector item that holds provenance and unaltered natural character. This semi transparent Burmese sapphire offers exactly that reassurance, because it combines classic blue intensity, a rare unenhanced state, and a respected laboratory certification. If your priorities are natural origin, no enhancement, and a shape that commands presence, this stone meets those priorities in a way that feels both elegant and unmistakable.

This sapphire weighs 3.98 carats, and it is a round shape with dimensions of 8.25 x 8.19 x 5.85 mm, measured to careful standards. The cut is a double cabochon, which means the gem is beautifully domed on both sides, producing a smooth, velvety surface and a serene play of color that changes with the light. The material is semi transparent, permitting depth of color without the fully faceted brilliance of a faceted stone, and this contributes to an immersive blue that feels deep and enveloping. Clarity is graded as very slightly included at eye level, which means there are natural inclusions visible under close observation, and these inclusions are not intrusive to the overall beauty. Color intensity is described as intense, delivering a vivid blue that is unmistakably sapphire, while the polish is excellent, giving the stone a luminous, glass like sheen across the dome. The origin is Burma Myanmar, a source renowned for producing some of the most desirable and historically revered blue sapphires, and this gem is certified by C.Dunaigre. The lab color classification is Blue, and importantly, the stone has undergone no enhancement, so you are acquiring a natural, untreated Burmese sapphire with documentation to support its attributes.

For someone planning a proposal, a signature piece, or an investment grade addition to a collection, the double cabochon Burmese sapphire is a compelling solution. Its rounded form makes it ideal for settings that showcase the dome, such as a bezel set solitaire for a modern, minimalist engagement ring, or a vintage inspired mount that highlights the gem as the central narrative of the design. If you are a collector who values natural state and provenance, the lack of enhancement elevates long term desirability, because unheated Burmese sapphires are prized for their rarity and stability. The gem works beautifully in bespoke designs where the metal finish and mounting can be chosen to enhance the blue, for example warm tones in 18 karat yellow gold will create a classic contrast, while platinum or white gold will present a contemporary, crisp frame that emphasizes the pure blue. Because the cut is a double cabochon, light pools across the dome, producing a sense of depth and a velvety saturation that is both calming and magnetic, which many clients describe as the kind of presence they have been searching for.

At The Natural Sapphire Company we understand that buying a gemstone is a personal journey, and we are committed to guiding you through choices with clarity and care. This sapphire comes to you with C.Dunaigre certification, confirming carat weight, dimensions, origin, clarity evaluation, color classification, and the absence of enhancement. That documentation preserves value and gives you confidence whether you intend to set the stone now or hold it as part of a curated collection. If you require help visualizing settings, our design team can suggest mounting ideas that complement the cabochon form, advise on prong counts and bezel styles that protect the dome while maximizing visibility, and provide simulated renderings to help you see the finished piece before fabrication. We can also discuss matching side stones, metal choices, and proportions to ensure the final piece reflects your personal style and the inherent beauty of this intense blue Burmese sapphire. Please let us know your priorities in terms of setting style, budget, and timeline, and we will recommend options that make this gem the perfect centerpiece for your story.
