Quite simply this is a stunning large aquamarine from Madagascar that shows the wonderful natural seafoam blue/green colour that gives aquamarine its name. Aquamarines in the market place are commonly heated to remove this gorgeous seafoam hue to turn it a standardized blue. This is a shame because this natural seafoam is absolutely fabulous and quite special. It is a lovely colour and this is a very fine gemstone. It is large, clean and very well cut and polished. It will make a cocktail ring par excellence!
