5.53 Ct. Blue Sapphire from Madagascar

This cushion shape blue sapphire weighing 5.53 carat is an exceptionally appealing choice for a bespoke jewelry commission, offering a generous face up presence at 9.92 by 9.56 by 6.30 mm. The mixed brilliant cut combines a faceting scheme that emphasizes both scintillation and color saturation, which in a vivid blue stone such as this produces lively flashes of light while maintaining a deep, velvety body color. The clarity is graded eye clean at eye level, which means an educated buyer can expect no visible inclusions when set, allowing the intense color and cut to read clearly in a ring or pendant. The excellent polish further enhances light return and texture, producing crisp facet junctions and a smooth surface. Origin reports indicate Madagascar, a source noted for producing sapphires with saturated, appealing tones and consistent crystal quality. The stone has been heat treated, which is a stable and widely accepted enhancement that optimizes tone and clarity without compromising durability, a factor important for everyday wear in rings or for heirloom pieces.

For custom jewelry the cushion outline and these dimensions are particularly advantageous, because the slightly rounded square silhouette adapts well to a variety of settings, including classic four prong solitaires, low profile bezel settings, intricate halo frames, and bold three stone compositions. The 9.92 by 9.56 mm platform sits comfortably on most finger sizes to provide a strong visual impact without appearing oversized, while the 6.30 mm depth preserves immersive color when viewed face up and allows skilled setters to balance gallery height and security. From a gemological perspective this combination of carat weight, eye clean clarity, vivid color intensity, and excellent polish creates a stone that is both beautiful and practical to work with, facilitating secure mounting and predictable light performance.
