We’ve researched our favorite sustainable jewelry brands for the best aquamarine jewelry pieces—these are our top picks for their quality and timeless design.

Happy birthday to all our March babies! We love the beautiful aquamarine birthstone, a calming and gentle blue that evokes peace and tranquility. Since birthdays between March 1- 20 are Pisces signs, this water-inspired stone feels more than fitting for the perfect gift.

What does aquamarine symbolize?

Aquamarine symbolizes tranquility, serenity, and clarity. It also embodies youthfulness, hope, and everlasting joy. Various cultures believe to instill courage, alleviate stress, and improve communication. Sometimes called the “sailor’s gem”, this beautiful stone is thought to have protected sailors from harsh seas, according to mythological ideas. Its soothing blue-green hue reflects the calming essence of water, making it a favored choice for both jewelry and decorative items.

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, and can be found as the standout stone in many jewelry pieces.

Our team has reviewed hundreds of sustainable jewelry brands, and we’ve selected our favorite aquamarine birthstone necklaces, rings, bracelets, and earrings from the brands below based on eco-friendly production practices, fairly sourced materials, and quality design.

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!
