Aquamarine

Named after seawater, aquamarine is the blue to slightly greenish-blue variety of beryl, coloured by trace amounts of iron. Unlike emerald, aquamarine crystals often grow to large sizes in granitic pegmatites, which allows cutters to fashion clean gems frequently exceeding ten to twenty carats. Its clarity and size potential make aquamarine a classic choice for cocktail rings, favoured by Art Deco designers and by contemporary designers for the same reasons.
