Tourmalineis one of October's birthstones and comes in many colors - but primarily in pink and green. 

 Aquamarine is March's birthstone and is a beautiful, medium priced, light blue or blue-green stone. It sparkles and shines so wonderfully that is it often made into an aquamarine/tourmaline engagement ring. Though this gemstone is wonderful in any setting, we found that aquamarine/tourmaline rings, aquamarine/tourmaline pendants and aquamarine/tourmaline earrings are the most popular aquamarine/tourmaline jewelry.
