Aquamarine

Aquamarine is the birthstone for March. It is a type of beryl, the same mineral as emerald, and is blue to blue-green. It is often found in large crystals and has relatively high transparency, so it can be enjoyed as large pieces of jewelry. The deep dark blue one is called ``Santa Maria Aquamarine'' and is highly valued.
