0.57 Ct. Blue Sapphire from Madagascar

One transparent 0.57 carat oval blue sapphire is presented, dimensions 5.19 x 4.44 x 3.07 mm, faceted with a mixed brilliant cutting style, intense color intensity, very slightly included clarity grade evaluated at eye level, and an excellent polish. The proportioned oval outline and mixed brilliant faceting produce balanced light return and a pleasing depth of tone, with siting that emphasizes blue saturation and internal scintillation. The stone is heat treated, a standard enhancement for sapphire that improves color uniformity and stability, and the sapphire is sourced from Madagascar. The Natural Sapphire Company provides this gem as a single, polished example suitable for precise setting applications where a compact, richly colored center or accent stone is required.

On the Mohs hardness scale this sapphire rates 9, second only to diamond which rates 10, and it therefore offers excellent resistance to scratches compared with many common gem materials such as topaz which rates 8, and quartz which rates 7. That high hardness contributes to long term durability for rings and other jewelry intended for frequent wear, while it is important to note that hardness is distinct from toughness, and all gemstones can suffer chips or fractures from sharp impact or improper handling. Heat treatment applied to this stone is a stable enhancement, and routine care with mild soap and a soft brush will maintain appearance, with professional inspection recommended after any hard impact or as part of regular maintenance when mounted. The 0.57 carat oval, with its refined cut and strong blue saturation, is well suited to delicate solitaire mounts or as a carefully matched accent in multi stone designs, and The Natural Sapphire Company can advise on secure settings and practical care to ensure the sapphire retains its optical and physical qualities over time.
