6.95 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for the perfect engagement gemstone, you are looking for beauty, meaning, and lasting quality, and this exceptional GRS certified Blue 6.95 carat marquise shape blue sapphire meets every expectation. At The Natural Sapphire Company we understand that an engagement ring must carry both an emotional story and technical excellence, and this stone delivers on both. The sapphire measures 17.80 x 7.59 x 6.72 mm, it is cut in a striking marquise profile with a mixed brilliant cut to maximize sparkle, it is transparent and eye clean at normal viewing distance, it shows vivid color intensity, and it has an excellent polish. Originating from Ceylon Sri Lanka, a source famed for producing sapphires with vibrant, lively blues, this gem has been heat treated to optimize color and clarity, a stable and widely accepted enhancement that maintains the stone at its most beautiful. The GRS certification gives independent verification of the stone characteristics and origin, so you can choose this center gem with confidence.

Consider how this marquise sapphire will perform as the focal point of an engagement ring, remembering that shape and proportion define presence on the hand. At 6.95 carats this sapphire offers a remarkable balance of scale and wearability, giving a strong visual impact without feeling oversized. The 17.80 x 7.59 mm outline creates an elegant, elongated silhouette that flatters most finger shapes by visually lengthening the finger. The mixed brilliant cut means expertly placed facets combine the scintillation of a brilliant style with areas of step cutting that enhance color saturation, so under varied lighting this sapphire will glow with lively flashes and deep blue flashes at the same time. Eye clean clarity assures you that the gem will read as pure and luminous to the naked eye, and the excellent polish ensures the surface reflects light cleanly for a mirror like finish. Together these qualities deliver a gem that is decisive, radiant, and unmistakably luxurious.

Practical considerations for a marquise center stone are important for long term enjoyment, and this sapphire is an excellent choice for an engagement ring that will be worn daily. Sapphire ranks nine on the Mohs hardness scale making it tough and resistant to scratches and knocks, and the heat treatment applied to this stone is a standard procedure that stabilizes and enhances its appearance without compromising durability. The marquise shape does require careful setting at the pointed ends to protect against potential chipping, and we recommend secure V prongs or a bezel tip to safeguard the edges while keeping the profile elegant. Metal choices can further influence the look, for example cool metals like platinum or white gold will emphasize the vivid blue and create a modern, crisp contrast, while warm metals like yellow gold or rose gold will soften the look and lend a vintage, romantic glow. Design styles that suit this stone include a clean solitaire to let the marquise speak for itself, a delicate halo to boost sparkle and perceived size, three stone designs for symbolism and balance, and intricate vintage inspired settings for those who want character and detail. At The Natural Sapphire Company we can advise on the ideal mounting to maximize beauty and security.

Beyond physical attributes, the emotional resonance of a Ceylon blue sapphire holds special appeal for couples choosing an engagement ring. Blue sapphires have a long tradition as symbols of fidelity, wisdom, and enduring love, and a vivid Ceylon blue elevates that symbolism with warmth and life. For someone seeking a signature piece that reads as both modern and timeless, this marquise sapphire fills that role with authority, offering a statement that will become part of your family story. The GRS certification and documented origin add provenance that appeals to collectors and sentimental buyers alike, while the eye clean clarity and excellent polish make it a stone that will photograph beautifully and shine in every setting.
