6.48 Ct. Blue Sapphire from Ceylon (Sri Lanka)

If you are searching for a single stone that ends the hunt for the perfect center gem, this GIA certified, transparent blue sapphire from Ceylon is a rare answer. We present a beautiful, GIA certified, vivid blue sapphire weighing 6.48 carats, cut into a classic oval, with dimensions of 13.13 by 9.49 by 6.20 millimeters. The mixed brilliant cut combines the best of brilliant facets to deliver scintillation, with step facets to preserve deep, even color. The clarity grade is very slightly included, evaluated at eye level, and the polish is excellent, which together mean the gem reads clean to most viewers, with lively surface sparkle and saturated hue. The stone has been heat treated, a stable and commonly accepted enhancement in sapphires, and its origin is Ceylon Sri Lanka, known for producing historic and highly sought after blue sapphires. At The Natural Sapphire Company we know that many clients are seeking more than a pretty stone, they want a gem that fits a design vision, and this sapphire fits both formal heirloom projects and contemporary bespoke pieces with equal grace.

The dimensions and oval shape make this sapphire especially adaptable for custom jewelry, which is what many clients need when creating an engagement ring or a showpiece pendant. The length of thirteen point one three millimeters and width of nine point four nine millimeters provide a broad face up area that reads larger on the finger than its carat weight alone might suggest. The depth of six point two zero millimeters is ideal for preserving light return and for secure setting, it gives lapidaries room to optimize the pavilion for maximum fire and depth of color. Oval shapes elongate the finger when set in rings, they sit beautifully in pendants and brooches, and they can be mounted east west for a modern silhouette or north south for a classic look. Because this sapphire has a mixed brilliant cut, it benefits from prong settings that allow light in from the pavilion facets, while bezel settings and halos are also excellent options to intensify the color and protect the stone in daily wear. For a client seeking durability and understated drama, a four or six prong setting in platinum will showcase the vivid blue with a contemporary feel. For a warmer, vintage tone, yellow or rose gold will gently lift the blue and create a rich contrast that suits both classic and modern designs.

When designing around a gem of this quality, understanding its clarity, cut and treatment helps you make choices that highlight its strengths and minimize compromise. The clarity, described as very slightly included at eye level, means that inclusions are minimal and will rarely be seen without magnification, allowing the sapphire to transmit its vivid color with unbroken intensity. The excellent polish ensures that facets are crisp, reflecting light evenly which makes diamond side stones and halos sparkle in sympathetic contrast. Heat treatment is disclosed and stable, and it improves hue and clarity without diminishing the structural integrity of the stone. The GIA certification included with this sapphire gives independent verification of weight, measurements, cut style, clarity observations, color intensity, and treatment. Origin from Ceylon Sri Lanka is an important provenance note for collectors and clients who value the storytelling behind a gem, as Ceylon sapphires have long been prized for their clean, pure blues. The inherent hardness of corundum, second only to diamond, means that this sapphire is an excellent choice for everyday wear, ideal for an engagement ring that must balance beauty with resilience, and suitable for pendants and bracelets where knocks are possible.

At The Natural Sapphire Company we tailor the custom design process to match your needs, whether you are commissioning an engagement ring, a cocktail ring that will be worn to celebrate milestones, or a one of a kind necklace crafted to hold a rare stone. For clients seeking a statement engagement ring, we often recommend a delicate diamond halo to intensify the center color, paired with tapered baguettes or pear shaped side sapphires for an artful three stone composition. For those who want durability and a low profile for an active lifestyle, a bezel or semi bezel with a slight raised crown will protect the girdle and allow the stone to sit lower on the hand. The oval form also lends itself to asymmetrical designs, with offset diamonds or a split shank to add personality without competing with the sapphire. We provide CAD renders and virtual try ons so you can see exactly how the proportions work on your hand, and we can suggest prong counts and angles that keep the gem secure while maximizing light return. We also facilitate matching, so if you desire a set of earrings or a pendant to accompany the ring, we can source complementary sapphires or diamonds that harmonize by hue and clarity. Every commission comes with the GIA report, professional photography, and guidance on care and maintenance, including best practices for cleaning, inspection intervals, and reassurance about the stability of heat treatment.

This Ceylon blue sapphire, with its generous face up size, ideal depth, mixed brilliant cut, and vivid color intensity, is an excellent foundation for a bespoke piece that will become a lifelong treasure. At The Natural Sapphire Company we listen to your needs, and we match this gem to the exact design solution that fulfills them, whether that means a classic solitaire with a modern twist, a dramatic halo set to showcase that vivid Ceylon blue, or a custom heirloom that will be passed down for generations. The balance of size and shape makes it versatile for many settings and styles, and the GIA certification and excellent polish give you confidence in the investment.
