Natural Sky Blue Aquamarine Octagon Cut 5.55Ct

A natural sky blue aquamarine from Brazil, 5.55ct in an octagon cut measuring 16.4x8.2mm. The stone shows a clean, light sky blue - cool and transparent, with a clear aqua tone reading well across the elongated form. A natural brownish inclusion is visible within the body at SI clarity, and the generous proportions give the stone real presence in hand.

At 16mm long and 8mm wide this is a notably elongated octagon - an unusual shape for aquamarine, with the cropped-corner rectangular geometry of an emerald cut but the characteristic eight-sided faceting. Suited to east-west pendant settings, long ring designs, or architectural pieces where something outside the standard oval or round is wanted. Untreated Brazilian aquamarine retaining its natural sky blue character. Natural aquamarine octagon Brazil, elongated octagon aquamarine loose, sky blue aquamarine 16mm, March birthstone.
