The March birthstone resembles a light blue color. The color is technically called aquamarine. It is a mixture between a blue and a green. It is often compared to a light turquoise color. The aquamarine stone was associated with water. People believed if this stone was emerged under water, it would have special powers. This stone comes in a few different variations of color. They are found to be either a blue-green color or a sky blue color. Both of these colors look great in any kind of jewelry piece. An alternate March birthstone is called bloodstone. This is a dark green stone with red spots. Instead of using this stone as a piece of jewelry, it is usually carved into different shaped beads. These beads can be used to create birthstone necklacepieces.
