0.42 Ct. Bluish Green Sapphire from Madagascar

Born in the mineral-rich soils of Madagascar, this sapphire carries the quiet memory of its birthplace, where ancient geology and seasonal rivers conspired to concentrate precious corundum. Extracted with care and passed to skilled cutters, the rough was shaped into a classic round form and given a mixed brilliant cut to balance sparkle and color. At 0.42 carat, with dimensions of 4.29 x 4.30 x 3.00 mm, this bluish green sapphire shows medium intense color that responds to light with a cool, oceanic glow, a quality enhanced by a careful heat treatment that deepened the hue while preserving the gem s natural character. The polish is excellent, and the proportions have been refined to maximize brilliance and life, creating a stone that fits beautifully into an elegant setting.

Viewed closely this gem reveals the tiny internal signatures that make each natural sapphire unmistakable, delicate needle like inclusions and minute reflective pinpoints scattered like distant stars. These fine needles catch and diffuse light, producing a gentle internal scintillation that complements the mixed brilliant faceting, while small isolated crystal inclusions and soft feathery wisps add depth and a living texture when the stone is turned. Subtle color zoning, a hallmark of many Madagascar sapphires, contributes to the bluish green shifting tone, so the gem can read more blue in cool light and more green in warmer light. The clarity grade is very very slightly included as evaluated at eye level, which means the inclusions are honest, natural fingerprints, visible only on close inspection and never detracting from the overall transparency and brightness.

Those internal features are not flaws, they are the sapphire s biography, evidence of formation under heat and pressure deep within the earth, and they give this gem a signature personality that no synthetic or heavily treated stone can replicate. Set as a solitaire or paired in a trio style, this 0.42 carat bluish green round sapphire will bring subtle color play and a sense of provenance to any design, a conversation piece that invites touch and telling. At The Natural Sapphire Company we honor that journey, presenting each stone with its story intact, and offering guidance to help your chosen setting celebrate the stone s natural inclusions and inherent beauty.
