What is aquamarine?
Aquamarine is the blue to blue-green variety of beryl, the same mineral family as emerald, and it is best known as the March birthstone and a stone of calm, clear communication. Its name comes from the Latin for “water of the sea”, and its colour, caused by traces of iron, ranges from the palest sky blue to a deep, clear ocean tone.
Beryl can grow in large, remarkably clean crystals, so fine faceted aquamarine is often almost free of inclusions. The beads and cabochons used in crystal jewellery are usually softer and more milky, with a gentle, watery translucence that many people prefer for everyday wear. Brazil is the classic source, alongside Madagascar, Nigeria, Mozambique and Pakistan. Many aquamarines are gently heated to remove a greenish tint and bring out a purer blue, a common and stable practice. In Chinese it is 海蓝宝 (hǎi lán bǎo), “sea-blue treasure”.
Aquamarine meaning
In crystal tradition, aquamarine is calming, soothing and cleansing. It is associated with truth, trust and letting go: the ability to speak honestly, listen well and release what you no longer need to carry. Its connection with the throat chakra makes it a favourite for anyone who wants to communicate with more ease and less tension, whether in a difficult conversation or a presentation at work.
Its lore is full of the sea. In ancient legend it was the treasure of mermaids, and sailors are said to have carried it as a talisman for calm waters and a safe return. Today it is a popular gift for March birthdays and for anyone who loves the ocean. Our 2026 zodiac guide also suggests aquamarine for those born in the Year of the Ox, for calm and clear communication.
How to wear aquamarine
Wear aquamarine as a necklace, where it rests close to the throat chakra. In crystal practice that is the traditional placement for a communication stone: a pendant or short strand at the base of the throat is said to keep its calming energy near your voice. A necklace also shows off aquamarine’s light, watery colour, which looks especially fresh against 925 sterling silver.
Aquamarine pairs gracefully with other blue stones. With chrysocolla it is said to encourage compassionate speech; with lapis lazuli, confident self-expression; and with amazonite, a cool head at work. If you love it as a bracelet too, many people wear it on the left wrist, the receiving side in crystal practice, though the necklace remains the traditional choice. Our guide to crystal necklaces covers how to choose one to wear close to the throat.
Aquamarine as a birthstone and gift
As the birthstone for March, aquamarine is a natural choice for birthdays that month, and in crystal lore it is also linked with Pisces and Scorpio. Its meaning makes it thoughtful for other moments, too: a gift for someone starting a new chapter, preparing for an important talk, or simply in need of a little calm. See our birthstones by month guide for the full calendar.
When choosing, colour is personal. Deeper blues are the most prized in fine jewellery, but the soft, misty blues of bead-grade aquamarine have their own quiet charm. Look for an even colour you love and a smooth polish; very saturated, uniform blue at a surprisingly low price may be glass or dyed quartz, so it is always worth asking.
Caring for aquamarine
At 7.5 to 8 on the Mohs scale, aquamarine is one of the harder stones in crystal jewellery and wears well every day. It can still chip or crack if knocked hard, especially bead-grade stones with natural fractures, so store it apart from other pieces.
- Clean gently. Warm water with a drop of mild soap and a soft cloth is ideal; avoid ultrasonic cleaners for included or bead-grade stones.
- Take it off for chores. Remove it before the gym, cleaning or cooking, so it avoids knocks and household chemicals.
- Store it softly. Keep it in a pouch or its own compartment, and in Singapore’s humidity let necklaces dry fully before you put them away.
Fitting its watery lore, many people cleanse aquamarine with moonlight or a quick rinse in cool water. Our cleansing guide explains the gentle methods.
