1.40 Ct. White Sapphire from Ceylon (Sri Lanka)

When you are searching for the perfect center stone to finish a bespoke engagement ring or to create a signature piece that will be worn every day, you want a gemstone that answers both the heart and the technical demands of a jeweler, and this white sapphire from Ceylon delivers on both counts. Offered by The Natural Sapphire Company, this transparent 1.40 carat round sapphire measures 6.58 x 6.56 x 4.60 mm, and it arrives to you with exceptional presence, a mixed brilliant cut that maximizes light return, and an excellent polish that gives each facet crisp definition. If your brief is clarity and versatility, this stone meets those needs with a clarity grade of very slightly included when evaluated at eye level, and a near colorless intensity that reads clean and bright next to modern metals. No enhancement of any kind has been applied, so what you see is the natural character and performance of a genuine Ceylon sapphire, and that authenticity is exactly what discerning customers seek when commissioning a custom piece.

Size and shape are the two most practical considerations when designing a custom mount, and the round outline of this sapphire makes it uniquely flexible for almost any design you can imagine. With a diameter in the high six millimeter range, the stone sits confidently as a solitaire, offering the visual weight comparable to many 1.25 to 1.50 carat centers while maintaining excellent balance for everyday wear. Its near perfect round dimensions, 6.58 by 6.56 mm, mean that a jeweler can set it in a classic four prong head, a secure bezel, a low profile tension setting, or a contemporary halo without compromise, and the 4.60 mm depth gives the stone enough pavilion to capture internal reflections and still sit well within standard ring cups. For pendants and solitaire studs the round silhouette is timeless, and for three stone or cluster designs the symmetry helps the sapphire integrate smoothly with tapered baguettes or small brilliant cut accent stones. The photographs show the gem on the hand, and note how the clean round table and balanced crown make it read larger than the numerical weight alone, an important factor when visual impact matters most.

Beyond its silhouette, the mixed brilliant cut and the excellent polish combine to create a lively, modern sparkle that complements both minimalist and ornate settings. The mixed brilliant approach marries a faceting pattern that enhances scintillation on the crown with a polished pavilion that returns light effectively, and the result is a stone that flashes white brilliance and attractive dispersion without introducing unwanted color tinges because of its near colorless body tone. With the clarity evaluation of very slightly included at eye level, most inclusions are minute and do not interrupt the stone s clean display, which is particularly important for center stones that must read bright and pure from a few feet away. The lack of any enhancement preserves the original optical properties of the sapphire, meaning its light behavior will remain stable and predictable when incorporated into white gold, platinum or yellow gold, and that natural state is a strong selling point for clients who want authenticity and long term value in the piece they commission.

From a practical design perspective this sapphire is a dream because it reduces the compromises that often come with bespoke work. The consistent round outline and the near symmetrical girdle dimensions allow a bench jeweler to create tight bezels or minimal prongs with confidence, and the medium depth of 4.60 mm gives mounting options that do not overly raise the stone from the finger, keeping the center durable for daily wear. For bridal designs the stone is large enough to carry a slim cathedral or tapered shank, and small accent diamonds or sapphires around a halo will amplify the center s presence without overwhelming its understated white beauty. If you prefer a solitaire, the stone s proportions allow for a delicate profile that still reads substantial, and if you prefer a statement halo, the round mixed brilliant facets will interact beautifully with surrounding brilliant cuts to create a sparkly, cohesive visual effect. For those considering alternative placements, the stone is equally suitable for a solitaire pendant or for an elegant single stud, and its optical clarity makes cleaning and maintenance straightforward, a plus for customers who want both beauty and practicality.

At The Natural Sapphire Company we understand that the search for the right gemstone is about more than numbers, it is about finding the piece that completes a story, and this 1.40 carat Ceylon white sapphire is a perfect conclusion for many design narratives. Its near colorless tone and natural, non enhanced origin from Sri Lanka give it an elegant neutrality that frames metal and side stones with clarity, while its mixed brilliant cut and excellent polish deliver consistent sparkle and refined appeal. If your brief is a ring that must balance presence with everyday wearability, or a pendant that must read crisp against the skin, or a pair of custom studs that require a standout center, this sapphire meets those needs with confidence.
