Aquamarine (or Ngoc Hai Lam) is the gemstone that represents the month of March. This March stone belongs to the Beryl stone family, named after the color of sea water but exists in two colors: blue and green. Aquamarine has excellent transparency, saturation and light tones, so it is almost impossible to find any dark or dark blue stones.

In ancient times, Aquamarine was believed to have healing powers, especially for the heart, liver and stomach. Today, the stone is associated by the gemological association with a symbol of youth, health, hope and love.

In addition, the traditional birth month gemstone of March is Bloodstone - a member of the Chalcedony stone family, with a striking blue color with orange or red spots, with a rich history in the Middle Ages.
