Happy birthday to all our March babies! We love the beautiful aquamarine birthstone, a calming and gentle blue that evokes peace and tranquility. Sometimes called the “sailor’s gem”, this beautiful stone is thought to have protected sailors from harsh seas, according to mythological ideas. Since birthdays between March 1- 20 are Pisces signs, this water-inspired stone feels more than fitting.

A few brief facts to tuck away while shopping for your birthstone piece: Gemologists believe aquamarine is blue in color because of the iron in the crystal. It’s found deep in the earth and the majority of sourcing sites today are in Pakistan and Brazil. Because this gem is plentiful, it’s usually quite affordable, too.

Whether you’re a March baby, love someone who has a birthday in March, or simply love this beautiful bluish-green gem, consider one of these aquamarine birthstone pieces from our favorite ethical and sustainable jewelry brands!
