|
30th January 2026

Discover the most serene gemstone of them all: aquamarine. Distinguished by its green-blue color, the birthstone for March is named after seawater and has a calming quality that reflects its association with the ocean. Aquamarine jewelry makes the perfect birthday or anniversary gift for anyone celebrating a milestone this month, but you’ll appreciate this beautiful gemstone all year round. Here’s what you need to know about March birthstone jewelry.

What is the March birthstone?

The March birthstone is aquamarine, a green-blue variety of the mineral beryl. It aligns very nicely with the corresponding sign of the zodiac, which is also inspired by the ocean: Pisces (19th February – 20th March) is a water sign symbolized by two fish swimming in opposite directions. As well as the March birthstone, aquamarine is the traditional gemstone to celebrate a 19th wedding anniversary.

What is aquamarine?

Aquamarine is a green-blue semi-precious gemstone. It’s a member of the beryl family, just like emerald, and shares many characteristics with its vivid green cousin. Beryl comes in a variety of different colors depending on trace impurities in the crystal structure, and the aquamarine variety owes its sea-blue color to traces of iron. With a moderate hardness, rating 7.5 to 8 on the Mohs scale, aquamarine is a durable choice for birthstone jewelry.

Thanks to its color, aquamarine has long been a symbol of the ocean. It’s named after the Latin words for ‘water of the sea’, and has a seafaring history dating back to ancient times: Roman fishermen associated the gemstone with the god Neptune and believed that it brought protection and good luck.



Where are aquamarines from?

Aquamarine is mined mainly in Brazil, the source of one of the most famous aquamarine gemstones in history. Weighing in at 1, 298 carats, it was a gift from the Brazilian President Getúlio Vargas to Eleanor Roosevelt, the First Lady of the United States, in 1936. Aquamarine is also found in Pakistan, Nigeria, Mozambique, Kenya, Madagascar and Zambia, as well as the US, China, Myanmar, Russia and Ukraine.

What does aquamarine symbolize?

Sea-blue in color, it’s no surprise that aquamarine is a symbol of the sea. It’s said that Roman sailors who were caught in a storm would throw aquamarines overboard into the water in a bid to appease the gods. The Romans also believed that aquamarine had healing properties, particularly when it came to matters of digestion.

Generally, aquamarine is associated with calm and clarity. Thought to promote happiness and harmony in marriage, aquamarine makes a meaningful addition to a personalized anniversary gift or even a wedding ring. And as a member of the beryl family, aquamarine is believed to provide protection in battle, too.

What to look for when buying aquamarine jewelry

Looking to buy aquamarine jewelry? Like any gemstone, aquamarine is rated according to its color, clarity, cut and carat weight. When it comes to color, aquamarine in darker shades of blue is generally considered more valuable. The carat weight can have an impact on the color: smaller stones tend to be paler, while more intense color is found in aquamarines weighing 5 carats or more. Clarity is also an important factor. Look for aquamarines that are even in tone with no visible inclusions.


What is birthstone jewelry?

Birthstone jewelry refers to earrings, necklaces, rings or bracelets that incorporate the wearer’s birthstone – a lovely way to make a gift more personal. Every month of the year is associated with its own gemstone. Aquamarine, for example, is the birthstone for March, while May shines the spotlight on emerald, another variety of beryl. More birthstones by month include garnet for January, ruby for July and topaz for November.

While birthstone jewelry gifts are a popular way to celebrate a birthday, they’ll add a thoughtful touch to any piece of jewelry. Many couples add each other’s birthstones to their wedding bands or have them set into anniversary gifts to commemorate the month they got married.

Is aquamarine expensive?

Aquamarine is classified as a semi-precious gemstone, and it’s more affordable than precious gemstones such as emerald, ruby, sapphire or diamond. While emerald is also a variety of beryl, it commands a higher price than aquamarine because of its rarity. Aquamarine, on the other hand, is relatively abundant. As with any kind of gemstone, the cost of aquamarine is ultimately determined by the quality of the individual gemstone and the interplay between color, clarity, cut and carat.

How to care for aquamarine

Aquamarine has a Mohs rating of 7.5 to 8, making it durable enough to take its place in jewelry that you wear every day. Here’s how to keep it looking its best:

  • Wash your aquamarine pieces in warm, soapy water
  • Clean your jewelry gently with a soft cloth or a very soft toothbrush if required
  • Dry with a lint-free cloth and make sure that it is thoroughly dry before storing
  • Treat your aquamarine birthstone jewelry to a professional clean every year or so
  • Remove aquamarine jewelry before swimming, showering or applying lotion

How to store aquamarine jewelry​
