Quick Answer: Aquamarine is one of March's two traditional birthstones, alongside bloodstone. It is the blue to greenish-blue variety of beryl and has long been associated with protection, calm, loyalty, happiness in marriage, and the sea. Aquamarine ranks 7.5–8 on the Mohs hardness scale, making it suitable for many types of jewelry. When buying aquamarine, consider color, clarity, cut, carat weight, treatment disclosure, setting, and supporting gemological information rather than relying only on labels such as "AAA."
Few gemstones capture the feeling of clear water and early spring as naturally as aquamarine. Its pale blue to greenish-blue color has inspired comparisons with the sea for centuries and gives March birthstone jewelry a calm, distinctive appearance.
Aquamarine's appeal is not limited to color. It has historical associations with sailors and safe voyages, traditional connections with harmony and happiness in marriage, and enough durability for many rings, earrings, pendants, and other frequently worn jewelry designs.
For modern buyers, however, understanding aquamarine requires more than knowing its symbolism. Color intensity can vary considerably, fine faceted stones are often expected to look clean to the eye, heat treatment is common, larger stones do not necessarily command the same per-carat premiums seen in some rarer gemstones, and seller-specific labels such as "AAA" are not universal gemological grades.
This guide explains the meaning of March's aquamarine birthstone, its color, history, symbolism, quality factors, treatments, care requirements, engagement-ring suitability, and what to check before choosing aquamarine jewelry.
What Does the March Aquamarine Birthstone Mean?
Aquamarine has traditionally been associated with calm, protection, loyalty, clarity, harmony, courage, and safe travel. Its connection with the sea is central to much of its historical symbolism.
Ancient mariners carried or wore aquamarine because they believed the gemstone could calm waves and protect sailors during voyages. Other historical traditions connected the broader beryl family with courage, friendliness, intelligence, and protection during conflict.
Over time, aquamarine also became associated with happiness and harmony in marriage. That connection continues in modern jewelry, where the gemstone can represent trust, calm communication, lasting partnership, and a relationship that remains steady through change.
These meanings belong to historical, cultural, and spiritual traditions. They should be understood as symbolism and gemstone lore rather than scientifically established therapeutic or protective effects.
Why Is Aquamarine a March Birthstone?
Aquamarine is one of the traditional birthstones associated with March. Its watery blue appearance makes the connection especially memorable as the month begins the transition toward spring in many parts of the Northern Hemisphere.
The word aquamarine derives from Latin terms meaning "water of the sea." Its name reflects the gemstone's characteristic range of watery blue and greenish-blue colors.
Aquamarine is a variety of beryl, the same mineral family that includes emerald, morganite, heliodor, and colorless beryl.
For someone born in March, aquamarine jewelry can therefore combine birth-month significance with a gemstone that has a long history in fine jewelry.

Does March Have Two Birthstones?
Yes. Aquamarine and bloodstone are both recognized as March birthstones.
The two stones look very different. Aquamarine is typically transparent to translucent and blue to greenish blue, while bloodstone is generally an opaque or semi-translucent dark green chalcedony marked by red inclusions.
This article focuses on aquamarine because it is especially common in faceted fine jewelry, engagement rings, earrings, pendants, and other designs where transparency and light return are important.
Someone choosing March birthstone jewelry does not need to own both stones. The better choice depends on personal style, color preference, jewelry type, and the symbolism that feels most meaningful to the wearer.
What Does Aquamarine Symbolize in Love?
Aquamarine has traditionally been connected with harmony, loyalty, trust, calm communication, and happiness in marriage.
Its gentle blue color gives it a very different romantic personality from intensely colored gemstones such as ruby. Rather than suggesting fiery passion, aquamarine is often chosen to represent steadiness, peace, emotional clarity, and a relationship built on trust.
That symbolism makes aquamarine suitable for engagements, anniversaries, promise jewelry, and other relationship milestones.
Aquamarine is also traditionally associated with the 19th wedding anniversary, making it an especially meaningful gift for couples celebrating nearly two decades together.
Aquamarine History and Sea-Born Symbolism
Aquamarine's connection with water begins with its name but extends deep into historical folklore.
Ancient sailors believed the gemstone could protect them at sea and calm dangerous waters. Historical traditions also attributed protective and intellectual qualities to beryl, the mineral family to which aquamarine belongs.
These ideas helped establish aquamarine as a gemstone associated with safe passage, composure, courage, friendship, and harmony.
Modern wearers do not need to believe the legends literally to appreciate their cultural importance. For many people, aquamarine's sea-inspired history simply adds another layer of meaning to its peaceful blue appearance.
Famous Aquamarines: From Eleanor Roosevelt to the Dom Pedro
Aquamarine has also appeared in historically important collections.
In 1936, the Brazilian government presented First Lady Eleanor Roosevelt with a remarkable dark blue rectangular step-cut aquamarine weighing approximately 1,298 carats. The gemstone is now associated with the Franklin D. Roosevelt Presidential Library and Museum.
Another celebrated specimen is the Dom Pedro Aquamarine, an enormous faceted aquamarine weighing more than 10,000 carats and fashioned into a tall sculptural obelisk.
These stones demonstrate one of aquamarine's unusual characteristics: gem-quality crystals can occur in very large sizes compared with many other popular colored gemstones.
What Color Is Aquamarine?
Aquamarine belongs to a relatively narrow color range that includes:
- blue;
- very slightly greenish blue;
- greenish blue;
- strongly greenish blue; and
- green-blue.
Most aquamarine found in jewelry has a relatively light, pastel appearance. More strongly saturated blue stones are less common and can be more desirable when color, transparency, and cutting work together attractively.
When comparing aquamarines, look beyond the simple word "blue." Consider:
- Hue: whether the stone appears blue, greenish blue, or somewhere between;
- Tone: how light or dark it appears; and
- Saturation: how strong or muted the color looks.
The "best" color is not purely a matter of price. Some buyers prefer a purer blue appearance, while others specifically enjoy the natural watery greenish-blue character that inspired the gemstone's name.
How Is Aquamarine Quality Evaluated?
Aquamarine quality should be evaluated through a combination of characteristics rather than one seller-created label.
The most useful factors are color, clarity, cut, carat weight, treatment, and overall appearance.
Color
Clarity
Cut
- emerald cut;
- oval;
- round;
- pear;
- cushion;
- marquise;
- heart; and
- designer or fantasy cuts.
Carat Weight
Treatment
Overall Appearance
Color is one of the most important considerations when comparing aquamarines.
Fine stones may show attractive medium to stronger blue or slightly greenish-blue color without appearing overly dark. Most aquamarine, however, is much lighter in tone.
Color can also appear stronger as aquamarine becomes larger, which is one reason small accent stones may look noticeably paler than a larger aquamarine center stone in the same piece of jewelry.
Fine faceted aquamarine is generally expected to have high transparency and few obvious inclusions when viewed without magnification.
This is an important difference between aquamarine and its beryl relative emerald. Visible inclusions are extremely common and often accepted in emerald, while fine transparent aquamarine is usually expected to look much cleaner.
Some aquamarines can contain hollow or liquid-filled tubes and other internal features. Material with more obvious inclusions may be used for cabochons, carvings, beads, or unusual optical effects rather than conventional transparent faceted jewelry.
Aquamarine can be fashioned into a wide range of shapes because suitable rough is relatively available and the material can show excellent transparency.
Popular cuts include:
A good cut should help the gemstone display attractive color and brightness while maintaining balanced proportions.
When viewing a faceted aquamarine, look for excessive windowing—an area through which you can easily see straight through the center rather than receiving attractive reflections from the facets.
Aquamarine crystals can occur in unusually large sizes, so carat weight behaves differently from gemstones that become exceptionally rare at relatively modest sizes.
Large aquamarines are therefore not automatically suspicious or synthetic simply because of their size.
In fact, larger stones can sometimes display stronger apparent color than small stones. Beyond very large jewelry sizes, however, greater weight does not always mean a proportionally higher per-carat price because demand for extremely large gemstones is more limited.
Many aquamarines are heated to reduce greenish tones and produce a more purely blue appearance. Heat treatment is widely encountered and considered stable.
Treatment does not automatically make an aquamarine undesirable. The important issue is accurate disclosure and understanding whether any treatment affects value or care.
Aquamarine should ultimately be judged as a complete gemstone.
A slightly lighter stone with excellent transparency and cutting may look more attractive to one buyer than a deeper blue stone with poorer proportions. Personal preference, intended jewelry style, and budget should all be part of the decision.
Browse aquamarine rings to compare how different cuts, stone sizes, settings, and metal colors affect the overall look.
Is Aquamarine Heat Treated?
Heat treatment is common in aquamarine.
Natural aquamarine can contain both blue and green components. Controlled heating may reduce the greenish component and create a more purely blue appearance.
This treatment is generally considered stable, meaning the resulting color is not expected to disappear during ordinary wear.
When comparing aquamarine jewelry, useful questions include:
- Has the gemstone been heat treated?
- Is any other treatment disclosed?
- Is the stone fracture filled?
- Does its treatment affect cleaning recommendations?
- Is an independent gemological report available if the stone's value warrants one?
The goal is not necessarily to avoid treated aquamarine. It is to understand what you are purchasing.
What Does AAA Aquamarine Mean?
You may see aquamarine described as AAA, AA, A, premium, fine, or similar quality terms.
These descriptions can be useful within an individual seller's own product system, but they are not universal standardized gemological grades for aquamarine.
One company's AAA aquamarine cannot automatically be assumed to match another company's AAA aquamarine.
When you see a seller-defined grade, look for the characteristics behind the label:
- What color range does it represent?
- How transparent is the stone?
- Are eye-visible inclusions accepted?
- What treatment has been disclosed?
- How is cutting evaluated?
- Are measurements and carat weight provided?
- Does the stone have supporting documentation where appropriate?
This gives you more useful information than the letters alone.
Aquamarine vs Blue Topaz: What Is the Difference?
Aquamarine and blue topaz can look similar at first glance, especially when both appear light or medium blue. They are nevertheless different gemstones with different mineral identities, treatments, rarity patterns, and birthstone associations.

Neither gemstone is automatically better. Aquamarine is the more relevant choice when March birthstone significance, beryl identity, or its traditional symbolism matters. Blue topaz may appeal to someone who simply wants a stronger blue color at a different price point.
For a deeper comparison, read our Aquamarine vs Blue Topaz guide.
Is White Aquamarine Real?
The phrase "white aquamarine" can be confusing.
Aquamarine is specifically the blue to greenish-blue variety of beryl. Colorless to nearly colorless beryl is generally known as goshenite.
That means a completely colorless beryl should not simply be assumed to be a normal blue aquamarine with an unusual marketing name.
If a product is described as "white aquamarine," ask the seller exactly what gemological material is being offered and whether any laboratory identification is available.
This distinction is especially useful when comparing online gemstone listings where color names may be used loosely.
Where Does Aquamarine Come From?
Aquamarine is found in several parts of the world.
Brazil has historically been one of the most important sources, particularly the state of Minas Gerais. Aquamarine is also found in Pakistan, where some deposits occur at high elevations in mountainous regions.
Other known sources include parts of:
- Madagascar;
- Nigeria;
- Mozambique;
- Zambia;
- Kenya;
- China;
- Myanmar;
- Russia;
- Ukraine; and
- the United States.
Geographic origin can be interesting, but it should not replace actual gemstone evaluation.
Aquamarine does not become high quality simply because it comes from a famous source. Color, transparency, cutting, treatment, dimensions, and overall beauty matter more to most jewelry buyers.
Can You Wear Aquamarine Every Day?
Aquamarine ranks approximately 7.5–8 on the Mohs hardness scale, making it a practical colored gemstone for many types of jewelry.
It is suitable for frequent wear when treated with reasonable care, including use in rings and engagement rings.
However, "durable" does not mean indestructible.
Aquamarine is less scratch resistant than ruby, sapphire, or diamond, and a hard impact can still damage a gemstone or its setting.
For aquamarine rings intended for frequent wear:
- choose a secure setting;
- consider a bezel, halo, or sturdy prongs for additional protection;
- avoid striking the gemstone against hard surfaces;
- remove the ring during heavy manual work;
- keep it away from abrasive materials; and
- have prongs and settings checked periodically.
The correct setting is especially important for engagement rings because they are usually worn far more frequently than occasional jewelry.
Why Choose Aquamarine for an Engagement Ring?
Aquamarine offers several qualities that make it attractive for non-traditional engagement rings.
Its light blue color is distinctive without being overpowering, and its traditional associations with harmony, trust, calm, and lasting partnership work naturally with the meaning of an engagement.
Its 7.5–8 Mohs hardness also makes it practical enough for regular ring wear when the stone is securely set and cared for appropriately.
Aquamarine pairs differently with each metal:
- White gold or platinum: emphasizes a cool, icy blue appearance;
- Yellow gold: adds warm contrast to the blue gemstone; and
- Rose gold: creates a soft, romantic contrast.
Diamond accents can increase contrast and brightness, while solitaire or bezel designs allow aquamarine itself to remain the main visual focus.

How Should You Clean Aquamarine Jewelry?
A conservative home-cleaning method is simple:
- Fill a small bowl with lukewarm water.
- Add a small amount of mild soap.
- Use a soft jewelry brush to clean gently around the aquamarine and its setting.
- Rinse carefully with clean lukewarm water.
- Pat dry with a soft, lint-free cloth.
Warm soapy water is the safest general cleaning approach.
Ultrasonic and steam cleaning can be suitable for many aquamarines when the gemstone does not contain fractures or liquid inclusions. However, if the treatment or internal condition of the gemstone is unknown, using warm soapy water is the more conservative choice.
Fracture-filled aquamarine deserves particular caution and should be cleaned gently.
Avoid prolonged exposure to intense heat, harsh household chemicals, or situations where the jewelry can strike a hard surface.
For a step-by-step cleaning guide, see How to Clean Aquamarine Jewelry.
How Can You Tell If Aquamarine Is Real?
Color and clarity alone cannot conclusively prove that a gemstone is aquamarine.
Several materials can resemble light blue aquamarine, including treated blue topaz, glass, and other blue gemstones.
For higher-value purchases, the most dependable way to verify identity is through qualified gemological testing.
Useful buying signals include:
- clear disclosure of the gemstone identity;
- measurements and carat weight;
- treatment information;
- high-quality photographs or video;
- seller return policies; and
- an independent gemological report when appropriate for the value of the piece.

Frequently Asked Questions About March Aquamarine
What is the birthstone for March?
Aquamarine and bloodstone are both traditional March birthstones. Aquamarine is the blue to greenish-blue variety of beryl and is especially popular in faceted fine jewelry because of its transparency, attractive color, and durability.
Does March have two birthstones?
Yes. March has two widely recognized birthstones: aquamarine and bloodstone. Aquamarine is typically transparent and blue to greenish blue, while bloodstone is generally dark green and opaque to semi-translucent with red inclusions.
What does aquamarine symbolize?
Aquamarine has traditionally symbolized calm, protection, harmony, courage, loyalty, safe travel, and happiness in marriage. These meanings come from historical and cultural gemstone traditions rather than scientifically proven effects.
What does aquamarine symbolize in love?
In relationship jewelry, aquamarine is commonly associated with trust, harmony, loyalty, calm communication, and lasting partnership. These associations make it meaningful for engagement rings, anniversaries, promise jewelry, and other romantic milestones.
What color is the March aquamarine birthstone?
Aquamarine ranges from blue to greenish blue and green-blue. Most stones have a light pastel appearance, while more strongly saturated blue material is less common and can be more valuable when combined with attractive transparency and cutting.
Is aquamarine suitable for an engagement ring?
Aquamarine can be suitable for an engagement ring because it ranks approximately 7.5–8 on the Mohs hardness scale. It still requires sensible care, particularly against hard impacts and scratching, so a secure setting is important for rings intended for frequent wear.
Is aquamarine usually heat treated?
Heat treatment is common in aquamarine and may be used to reduce greenish tones and create a more purely blue appearance. The treatment is generally stable. Buyers should still ask what treatment has been disclosed for the specific gemstone they are considering.
What does AAA aquamarine mean?
AAA is a seller-defined quality description rather than a universal standardized aquamarine grade. Different businesses may define AAA differently, so buyers should compare the actual color, transparency, cut, treatment disclosure, dimensions, and supporting documentation instead of relying on the letters alone.
Is white aquamarine real?
Aquamarine is the blue to greenish-blue variety of beryl. Colorless or near-colorless beryl is generally known as goshenite. If a gemstone is sold as "white aquamarine," ask the seller to clarify its exact gemological identity.
What is the difference between aquamarine and blue topaz?
Aquamarine is a variety of beryl and naturally occurs in blue to greenish-blue colors, while blue topaz belongs to a different mineral family and much commercial blue topaz receives treatment to produce its color. Aquamarine is also a traditional March birthstone.
Why can a large aquamarine still be natural?
Aquamarine can form in unusually large gem-quality crystals, so large faceted stones are more available than similarly large fine examples of some other gemstones. Size alone therefore does not prove that an aquamarine is synthetic or imitation.
How should aquamarine jewelry be cleaned?
Warm water, mild soap, and a soft brush are a safe general method for cleaning aquamarine jewelry. Ultrasonic or steam cleaning may be suitable for many stones when fractures or liquid inclusions are absent, but warm soapy water is the more conservative option when treatment or internal condition is unknown.
Where does aquamarine come from?
Important aquamarine sources include Brazil and Pakistan, with additional deposits found in countries such as Madagascar, Nigeria, Mozambique, Zambia, Kenya, China, Myanmar, Russia, Ukraine, and the United States. Geographic origin alone does not determine gemstone quality.
What makes aquamarine valuable?
Aquamarine value depends on the interaction of color, transparency, cut, carat weight, treatment, and overall beauty. More intense attractive blue color and high transparency are generally desirable, but buyers should evaluate the complete stone rather than relying on one characteristic or marketing grade.
Final Thoughts: Why Aquamarine Remains a Meaningful March Birthstone
Aquamarine has remained popular because its visual character and symbolism complement one another. Its clear sea-blue appearance suggests calm and openness, while centuries of gemstone lore connect it with safe travel, harmony, loyalty, courage, and happiness in marriage.
For someone born in March, that gives aquamarine immediate personal significance. For an engagement or anniversary, its traditional association with lasting partnership adds another layer of meaning. And for anyone who simply prefers light blue gemstones, aquamarine offers a distinctive alternative to more intensely colored stones.
The best purchase, however, comes from understanding what you are buying. Compare color and transparency, look at cutting rather than carat weight alone, ask about heat treatment, understand seller-defined quality labels, choose a secure setting for frequent wear, and consider independent gemological documentation when appropriate.
