Aquamarine is beryl distilled to its most serene expression — a stone so internally clear that the finest specimens resemble a column of frozen Arctic ocean.
This 30.48 carats Aquamarine of Greenish Blue moderately strong hue from Brazil was selected for the Skyjems Archive not as an afterthought, but as a deliberate acquisition. Fine, deeply saturated aquamarine with minimal greenish secondary hue is increasingly rare as the great Brazilian deposits are progressively depleted. Brazil's geological diversity — from Minas Gerais to the Amazon basin — has made it the world's most prolific producer of collector gemstones.
