9.53 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

This 9.53 carat cushion shape blue sapphire measures 11.46 x 10.65 x 8.08 mm, and features a traditional sugar loaf cut with a high dome and a smooth, polished surface. The stone is transparent, evaluated as slightly included at eye level, which indicates that inclusions are present but not intrusive to the overall appearance or durability. The color is described as vivid in intensity, a strong and attractive blue saturation that benefits from the sugar loaf profile by concentrating color towards the center. The polish is excellent, producing lively surface luster and a deep velvety sheen that highlights the gemology of this piece. The sapphire has undergone standard heat treatment, a widely accepted enhancement in the trade that stabilizes and enhances color without compromising the structural integrity of corundum. Origin is Ceylon Sri Lanka, a source renowned for producing sapphires with a characteristic lively blue hue and excellent color distribution, and this provenance contributes to the gems desirability and collectability.

For the educated buyer this sapphire represents a combination of measurable quality factors, provenance, and practical versatility. The carat weight approaching ten carats together with vivid color intensity makes it immediately suitable for a single stone pendant or a platform ring, where the cushion sugar loaf form offers a classic and elegant silhouette. Slightly included clarity at eye level is common in natural material and often preferable to stones that are overly treated or subject to clarity enhancement, it indicates natural origin and typically does not diminish durability. Heat treatment is fully disclosed and is an accepted practice that enhances marketability, while Ceylon origin provides a trusted geographic pedigree. At The Natural Sapphire Company we emphasize transparency in grading and disclosure, and we can provide further documentation upon request to verify treatment and origin. This stone combines substantial weight, desirable Ceylon color, sound gemological characteristics, and superb finish, making it a compelling choice for buyers who value natural origin, documented enhancements, and enduring aesthetic quality.
