3.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional, GIA certified deep blue sapphire weighs 3.13 carats, and measures 9.27 x 7.59 x 5.69 mm, with an elegant oval outline that flatters both classic and contemporary settings, and a mixed brilliant cut that combines the depth and contrast of step facets with the scintillation and fire of brilliant facets, resulting in extraordinary light return and dynamic brilliance. The stone exhibits vivid color intensity, a truly saturated deep blue that remains lively under varied lighting, and a clarity grading of very slightly included, evaluated at eye level, which indicates minimal, well hidden inclusions that do not detract from the gem one bit. The polish is excellent, enhancing facet definition and allowing crisp reflections across the table and crown facets, while the pavilion proportions and the 5.69 mm depth contribute to strong internal reflection and a lively face up presence. Enhancement by heat treatment is disclosed, a stable and widely accepted practice in corundum that improves color without compromising structural integrity, and the sapphire is sourced from Ceylon, Sri Lanka, a provenance renowned for producing some of the world’s most desirable blue sapphires.

For the discerning buyer, this sapphire represents a rare combination of size, color and cut, and is especially valuable to an educated collector who appreciates documented quality and traceability, as provided by the GIA report and our provenance documentation. The gem’s deep, vivid blue is characteristic of fine Ceylon material yet retains the clarity and brilliance that make it suitable as the centerpiece of a high end ring or pendant. With a hardness of 9 on the Mohs scale, sapphire offers exceptional durability for daily wear, while the mixed brilliant cut maximizes both sparkle and depth, making the stone visually larger than many stones of similar carat weight. At The Natural Sapphire Company we include full disclosure of treatment, certification, and origin, and we can assist with custom mounting options that preserve the stone’s optics and emphasize its oval silhouette. This sapphire is an investment in beauty and provenance, ideal for collectors and connoisseurs seeking a spectacular, reliably documented Ceylon blue sapphire that will be treasured for generations.
