March's birthstone is a shade of blue called aquamarine. The intensity of the blue varies and can be either deep or light, and it may also have a green tone to it. Some places where aquamarine gemstones can be found include Brazil, Pakistan and Nigeria.
Aquamarine is a color connected to the sea and themes like hope and health. The color is also sometimes used for a couple's anniversary. Aquamarine gemstones in darker shades are known as rarer than the lighter shades, so they cost more.
Although aquamarine is known as the primary birthstone, March also has bloodstone as its secondary birthstone, and its color is dark green and has some red spots on it.
