What Is Aquamarine?

Aquamarine is the pale blue to blue-green variety of the mineral beryl, colored by trace iron that sits within the same hexagonal framework that produces emerald. The name joins the Latin aqua marina, meaning sea water, a description earned by its cool, watery hue. It rates 7.5 - 8 on the Mohs hardness scale.

With a Mohs hardness of 7.5 to 8, aquamarine is durable enough for rings, pendants, and earrings worn daily with reasonable care. The International Mineralogical Association symbol for beryl is Brl, and gem-quality aquamarine is one of its most abundant varieties.

Aquamarine crystallizes in granitic pegmatites, where slow cooling allows beryl to grow into long prismatic crystals that sometimes reach several feet in length. Brazil's Minas Gerais state, Pakistan's Skardu region, and Nigeria's Jos Plateau supply most commercial rough to cutters.

Top color is traditionally called Santa Maria, a rich medium blue named after the Santa Maria de Itabira mine in Brazil. Most modern Santa Maria-grade material now comes from Mozambique, where African deposits produce a similar saturated blue tone.

Clarity standards for aquamarine are stricter than for most colored stones because large, clean crystals are common. A well-cut aquamarine should appear eye-clean, with any inclusions confined to the pavilion where faceting hides them.

Most commercial aquamarine is heat-treated to remove a faint greenish tint, producing the pure blue most buyers expect. The treatment is stable, standard in the trade, and disclosed by reputable sellers.

Meaning and Symbolism

Aquamarine has been carried by sailors for more than two thousand years as a talisman against rough seas. Roman mariners believed the stone could calm waves, and the Greeks associated it with the sea god Poseidon, whose temples often held carved beryl offerings.

Medieval Europeans placed aquamarine under pillows to inspire prophetic dreams and resolve disputes fairly.

The stone is traditionally given as the March birthstone in the United States, where it has been formally listed since 1912. Aquamarine is also the gift for nineteenth wedding anniversaries, symbolizing a marriage that has weathered many tides together.

In royal jewelry, aquamarine reached new prominence when the people of Brazil gifted Queen Elizabeth II a matching necklace and earrings from Minas Gerais in 1953. That set remains one of the most photographed pieces in British state wear.

In modern crystal practice, aquamarine is traditionally associated with clear communication, honest emotional expression, and steady nerves. Practitioners believe the stone links the throat and heart chakras, helping speech rise from genuine feeling rather than fear.

Many find it a useful companion during difficult conversations, public speaking, or periods of grief when words feel hard to reach.

Healing Tradition

The following describes cultural and historical traditions only. This is not medical advice. Read our full medical disclaimer.

Emotional

Practitioners believe aquamarine is a stone of clear feeling and honest speech. In crystal healing tradition, it is said to soothe reactive emotions, cool hot tempers, and help the wearer name what they actually feel rather than what they think they should feel.

Many find aquamarine supportive during grief, anxious transitions, and long travel, with the stone traditionally associated with emotional steadiness rather than suppression. Practitioners often pair it with rose quartz when the work involves softening after a hard period, or with amethyst when sleep has been disturbed by worry.

Aquamarine is also said to support people who over-apologize or speak around the truth, giving them a quiet confidence to say what they mean. It is not considered an energizing stone; readers looking for motivation usually turn to warmer gems like carnelian or ruby instead.

Spiritual

In crystal healing tradition, aquamarine is said to bridge the throat and heart chakras, linking emotional truth to the voice that expresses it. Practitioners believe this combination is what makes aquamarine the classic stone of honest communication, whether in journaling, prayer, or difficult conversation.

Many find aquamarine useful in meditations centered on water imagery, breathwork, or the tides of feeling. The stone has long been used in sea blessings, ocean crossings, and rituals around fluidity and flow. Modern practitioners often carry it during long journeys, whether physical travel or personal transitions.

Aquamarine is traditionally associated with the Moon and Neptune in Western astrology, which practitioners interpret as intuition softened by gentleness. Holding an aquamarine during evening reflection is a common practice; so is placing one in a bowl of water on the windowsill during a full moon.

Physical

Practitioners believe aquamarine supports what they describe as the body's water element, and it has long been used in traditions that link gems to the throat, the lymphatic flow, and cooling the nervous system.

Folklore associates aquamarine with sore throats, jaw tension, and the strain of speaking at length, and many find wearing it as a pendant near the collarbone comforting during seasonal colds or long meetings. In Ayurvedic gem therapy, aquamarine is said to balance excess heat in the head and chest.

Aquamarine is not a substitute for medical care, and practitioners frame its role as supportive rather than curative. For readers who run cold easily or feel emotionally adrift, crystal healing tradition sometimes recommends pairing aquamarine with a warmer stone such as sunstone or citrine to keep the energy balanced.

“I speak clearly, I feel honestly, and I move through change with the calm of still water.”

Zodiac, Birthstone and Gifts

Aquamarine is the modern US birthstone for March, shared by late-winter Pisces and the tail end of Aquarius. Astrologers traditionally associate aquamarine with the watery element and the Moon, which practitioners say mirrors the Piscean gift for feeling and intuition.

For Pisces, aquamarine is said to ground the sign's fluid emotions into clear communication, giving shape to feelings that can otherwise blur. For Aquarius, the stone is believed to soften the air sign's detachment with compassion.

Practitioners suggest wearing aquamarine in silver or white gold, often on the left hand near the heart line, and rinsing it briefly at each new moon to refresh its clarity.

Care and Cleansing

Aquamarine is among the easier stones to cleanse because it tolerates most common methods. Running tap water for under a minute is safe for a loose, unset aquamarine, as is a brief rinse in lukewarm soapy water with a soft brush to remove skin oils from jewelry.

Avoid long soaking for any set stone, since adhesives in older mountings can weaken over time.

Moonlight cleansing is traditionally preferred for aquamarine because of its watery associations; an overnight rest on a windowsill during a full moon is considered ideal. Sunlight cleansing should be brief, no longer than fifteen minutes, to avoid any gradual color shift in pale stones.

Smoke cleansing with palo santo or cedar, sound cleansing with a singing bowl, and recharging on a clear quartz cluster are all considered safe and gentle methods for this stone.

Important care warnings
  • DO rinse aquamarine jewelry in lukewarm soapy water and dry with a soft cloth after long wear.
  • DO NOT use ultrasonic or steam cleaners on aquamarine, especially stones with visible fissures or fracture fills.
  • DO store aquamarine separately from harder gems like sapphire or diamond that can scratch it.
  • DO NOT expose aquamarine to prolonged direct sunlight, since extended UV can slowly fade pale stones.
  • DO remove aquamarine rings before gardening, housework, or gym sessions where hard impacts are likely.
  • DO ask sellers to disclose any heat treatment or fracture filling at the point of purchase.
  • Note: store loose crystals in soft pouches to protect polished edges from chipping.

Real vs Fake

A genuine aquamarine is usually eye-clean with only faint inclusions visible under magnification. Typical natural inclusions include fine hollow tubes that run parallel to the crystal axis, tiny two-phase inclusions with liquid and gas, and occasional flat mineral platelets.

A stone sold as aquamarine that shows obvious curved gas bubbles or swirl marks under a 10x loupe is almost certainly glass.

Common imitations include blue glass, pale blue synthetic spinel, and heat-treated blue topaz misrepresented as aquamarine. Blue topaz is usually a deeper saturated blue with a higher specific gravity and a different refractive index, which a jeweler can confirm in seconds.

Synthetic aquamarine exists but is uncommon in the trade because natural material is plentiful enough not to justify the cost of growing it.

Practical at-home checks include weight and feel; aquamarine is noticeably denser than glass of the same size and cooler to the touch. A genuine stone should also scratch window glass easily but will itself scratch if rubbed against a sapphire or diamond tester tip.

For any aquamarine over two carats, a report from an independent gemological lab is the most reliable check for origin and treatment. Reputable sellers disclose heat treatment openly, since it is standard and stable.

Aquamarine Jewelry & Gifts

Aquamarine pricing depends on color saturation, clarity, size, and origin. Pale commercial aquamarine in small sizes starts around $30 to $80 per carat, while well-saturated medium-blue stones run roughly $100 to $400 per carat through reputable online retailers.

Santa Maria-grade material with a rich vivid blue can exceed $800 per carat above three carats, and unheated top-color specimens reach $1,500 and beyond at auction.

Heat treatment is standard in the trade and does not require a price discount if disclosed. Unheated stones command a modest premium among collectors, and origin documentation for Santa Maria, Mozambique, or Pakistan material can add further value.

For engagement rings or heirloom pieces, ask for a report from GIA, Mindat, and USGS confirming variety, origin, and any treatments. Avoid stones marketed as aquamarine that look unusually deep or electric blue, as these are often heat-treated blue topaz sold under the wrong name.
