Icy aquamarine is a gemstone that truly captures the beauty of the clear, open ocean. The depth of its blues will bring out gorgeous hues in blue eyes and stunning tones in cool complexions. Try a single square-cut stone for a simple, classic look or check out a HALO design, with the sparkle of the aquamarine set off by a halo of white diamonds. Aquamarine is especially gorgeous when set into white gold or silver and will have you dreaming of white-sand coastlines and shimmering, blue horizons.
