7.90 Ct. Blue Sapphire from Madagascar

This Royal Blue cushion shape sapphire is a technically refined stone that exhibits rare combination of size, color purity, and cutting precision, supplied and GIA certified by The Natural Sapphire Company. Weighing 7.90 carat, and measuring 11.91 x 9.64 x 7.42 mm, the gem has been cut to a mixed brilliant geometry, pairing a brilliant facet arrangement on the crown with well proportioned pavilion facets that maximize return of light while preserving weight. The mixed brilliant approach enhances scintillation and creates a deep, even color distribution across the table, while the excellent polish and careful facet junctions deliver crisp facet outlines and minimal light leakage. Clarity is graded as very very slightly included at eye level, indicating that any internal features are minute and do not affect transparency or visual performance to the naked eye. Color is described as vivid with a pure, saturated royal blue tone, and the stone is unenhanced, retaining original crystal chemistry and natural zoning from its Madagascar origin. From a gemological perspective the combination of strong saturation, high transparency, and the mixed brilliant cut produces both lively brilliance and the velvety depth expected from top grade blue sapphire.

For an engagement setting this sapphire is an ideal technical and aesthetic choice, offering both statement scale and everyday wearability. Sapphire rates nine on the Mohs scale, providing excellent resistance to abrasion for daily wear, and the cushion outline balances finger presence with comfortable proportions. The mixed brilliant cut mitigates the visibility of the very very slight inclusions and accentuates flashes of blue and violet under varied lighting, making the center of the ring read as saturated and lively in both daylight and artificial light. Recommended mounting styles include a low profile four or six prong setting to showcase the pavilion depth, or a semi bezel combined with a halo of melee diamonds to amplify perceived size while protecting the girdle. Because the gem is untreated, the color stability and market value are preserved, and the included GIA report supports provenance and quality. At The Natural Sapphire Company this Madagascar Royal Blue sapphire is presented with full technical disclosure, making it a compelling, responsibly sourced option for a discerning engagement ring that values craftsmanship, durability, and natural, vivid color.
