1.08 Ct. Greenish Blue Sapphire from Madagascar

This 1.08 carat round greenish blue sapphire presents precise dimensions of 6.30 by 6.29 by 3.69 millimeters, yielding an approximate depth of 58.7 percent, a proportion that supports balanced light return in a mixed brilliant design. The mixed brilliant cut combines a brilliant style crown with a pavilion optimized for depth and durability, translating rough material into scintillation without sacrificing weight. Facet junctions are executed to an excellent polish, producing crisp facet planes that promote contrast between pavilion flashes and crown brilliance. Clarity is graded as very slightly included at eye level, indicating inclusions that do not materially interrupt the visual field to the unaided eye, and this clarity combined with the transparent body color enhances the stone’s overall face up appeal. Color is described as greenish blue with a dark intensity, a saturation profile that yields deep, oceanic tones under daylight and a cooler tealean cast under mixed lighting, the dark intensity accentuating blue dominance while permitting subtle green modifiers to appear at certain angles. The sapphire is heat treated, a standard and stable enhancement that improves color saturation and clarity, and the material is sourced from Madagascar, a locale known for producing a wide range of blue to teal sapphires with distinct local signatures.

Rarity in this example is notable in two technical dimensions, size and color. At just over one carat in a round mixed brilliant format, the combination of a dense greenish blue hue with very slightly included clarity is less common than comparable commercial blues, making this a collector grade option for connoisseurs seeking a darker, more nuanced blue with green undertones. Compared to typical commercial blue sapphires that favor lighter or purer blue tones, this stone’s dark intensity and greenish bias make it rarer and more distinctive for bespoke jewelry applications. The proportions and excellent polish make it suitable for low profile or bezel settings that protect the girdle, or for classic prong mounts that maximize visible brilliance, and the cut conserves weight while maintaining optical performance. For clients who value documented origin, stable enhancement, and a unique color signature, The Natural Sapphire Company offers this Madagascar sapphire as a technically refined specimen that stands out among similar options for its balanced proportions, restrained inclusions, and uncommon greenish blue presence.
