0.74 Ct. Greenish Blue Sapphire from Nigeria

This transparent 0.74 carat emerald cut greenish blue sapphire measures 5.60 x 4.50 x 2.93 mm, exhibiting an elegant rectangular step cut with balanced proportions and an ample table. Graded as very very slightly included at eye level, the stone presents exceptional clarity for its size, and its intense color intensity is evenly distributed across the pavilion and crown. The sapphire is free of enhancement, retaining its natural color and internal characteristics from its Nigerian origin, and it has been finished with an excellent polish that maximizes light return from the step facets. The emerald cut emphasizes the stones color and internal structure while maintaining a refined, architectural appearance, making it well suited to settings that highlight both color and faceting precision.

From a durability perspective this sapphire is well suited to daily wear in a variety of jewelry types. As a corundum species, sapphire ranks nine on the Mohs scale of mineral hardness, offering superior resistance to scratching compared with most gem materials. The stone also demonstrates robust toughness, and in practice it tolerates routine impacts and abrasion associated with everyday use when set appropriately. The absence of enhancement increases its structural stability, there are no fillings or diffusion treatments that could be compromised by wear, and the excellent polish reduces the likelihood of microabrasion. The gem is chemically stable and lightfast, and it resists common household chemicals and exposure to sunlight, though care should be taken to avoid sudden temperature extremes. For daily wear we recommend secure settings that protect the girdle and corners, such as low profile bezels or well seated prong designs, and routine cleaning with warm soapy water and a soft brush. Periodic professional inspection will ensure settings remain secure and the stone maintains its presentation. At The Natural Sapphire Company we document provenance and grading to provide clients with a clear understanding of durability and suitability for daily wear, and this Nigerian emerald cut sapphire represents a durable, natural choice for ring, pendant, or pair settings where consistent performance is required.
