23.58 Ct. Greenish Blue Aquamarine from Brazil

This exceptional, GIA certified greenish blue aquamarine weighs 23.58 carats, with dimensions 20.84 millimeters by 16.43 millimeters by 10.22 millimeters, a radiant shaped, faceted treasure cut to reveal the fullest depth of its intense color. Transparent and eye clean when evaluated at eye level, it displays an impressive clarity that allows light to dance through every facet, and an excellent polish that amplifies its brilliance. The radiant cut brings both symmetry and fire, producing broad flashes of icy teal and sea blue across a generous table, while a careful, gentle heat treatment enhances its stable hue, a standard and disclosed practice that reveals the stone at its most expressive without compromising integrity. Complete with documentation from GIA, this aquamarine is offered in a single, rare size and proportion that is increasingly scarce in the market, an opportunity for a collector to possess a statement gem that reads as both refined and unmistakable.
