Origins and Composition
Aquamarine is a variety of beryl (Be₃Al₂Si₆O₁₈), from the same family as emerald. Its characteristic color, ranging from pale blue to intense blue-green, is due to the presence of ferrous iron in its crystal structure. It forms in granitic pegmatites and hydrothermal veins, often alongside tourmaline, topaz, and quartz.
The most beautiful deposits are found in Brazil (notably in Minas Gerais), Russia (Ural Mountains), Pakistan, Afghanistan, Madagascar, and Mozambique. Crystals can reach exceptional sizes—some specimens weighing several kilograms have been discovered.
A Spellbinding Palette of Blues
Aquamarine comes in a spectrum of incredibly subtle blues:
- Pale sky blue: the most common, light and luminous shade, evoking the marine horizon.
- Aqua blue-green: the most prized hue, reminiscent of shallow tropical waters.
- Deep blue: rarer, intense, and precious, sought after in high-end jewelry.
- Santa Maria blue: the most coveted variety, an intense and saturated blue, originating from Brazil.
Its transparency and vitreous luster give it incomparable luminosity, which plays magnificently with natural light.
Virtues and Properties in Lithotherapy
In lithotherapy, aquamarine is associated with the throat chakra and the element of water. It is renowned for:
- Soothing emotions: like waves smoothing sand, it calms inner storms, reduces stress, and promotes serenity.
- Strengthening courage: a stone for sailors and travelers, it provides protection during difficult journeys—both literally and figuratively.
- Facilitating communication: linked to the throat chakra, it helps to express thoughts with clarity and kindness.
- Stimulating clairvoyance: it promotes intuition, meditation, and connection to one's inner wisdom.
- Purifying and regenerating: associated with water, it is considered a stone of purification, both physical and emotional.

Aquamarine in History and Cultures
Greek and Roman sailors wore aquamarine amulets to protect themselves from storms and shipwrecks—it was considered the treasure of mermaids. Egyptians used it in their funeral adornments to ensure a serene passage to the afterlife. In the Middle Ages, it was reputed to reveal truth and expose lies.
Aquamarine is the birthstone for March, a symbol of spring renewal and rebirth. It is also associated with the 19th wedding anniversary, symbolizing the depth and fidelity of lasting love.
Aquamarine in Jewelry
With a hardness of 7.5 to 8 on the Mohs scale, aquamarine is durable enough for everyday wear. It suits all cuts—oval, cushion, emerald, pear—and pairs beautifully with white gold, silver, and platinum, which enhance its aquatic reflections.
Its transparency makes it a stone of choice for fine jewelry pieces: solitaires, pendants, earrings, and bracelets. It combines wonderfully with diamonds, pearls, and moonstones for compositions of timeless elegance.
How to Care for Your Aquamarine
Aquamarine is relatively robust, but a few precautions are necessary:
- Clean it with warm, soapy water and a soft brush.
- Avoid ultrasonic cleaners if the stone has inclusions or fractures.
- Protect it from prolonged sun exposure, which can discolor paler shades.
- Store it separately from harder stones to prevent scratches.
To energetically recharge it, place it under moonlight or near a source of running water. Avoid salt, which can alter its surface.
