The very name, Aquamarine, brings to mind the limpid, clear blue tint of the sea. Many Aquamarines are greenish when mined and cut. For those who prefer the purer blue, these gemstones are heated to enhance their blue color permanently. Some Aquamarine fanciers prefer the greenish hues, saying the greener tones remind them more of the sea. The color tones of Aquamarine are subtle and varied. Its soft luster is a wonderful addition to any natural colored gemstone jewelry collection.
