15.09 Carat Blue MADAGASCAR Cushion Sapphire AGL Non Heated

This 15.09 carat Madagascar sapphire is a cushion-cut blue stone presented as a loose gem. The stone is unheated, meaning its color is natural and unenhanced through thermal treatment. It carries certification from the American Gemological Laboratories (AGL), which has verified both its authenticity and treatment status. The specimen's significant carat weight and cushion shape make it suitable for a substantial center stone in jewelry design.
