The birthstone for March is one of my favorites (I know that I always say that but this time it is REALLY true). The name aquamarine was derived from an old Latin expression which meant ‘seawater’. I adore the multiple shades of blue-green that it comes in. It is a soft and sultry gemstone that looks good on almost everyone. Aquamarine is the blue-green variety of beryl, emerald is the green variety.
