March Birthstone
Aquamarine
The birthstone of courage, serenity, and honesty — treasured by sailors for centuries
Quick answer: The birthstone for March is Aquamarine.
Aquamarine is the modern birthstone for March (with bloodstone as the traditional alternative), celebrated for its serene blue color, excellent clarity, and ancient connection to the sea.
What Is the Birthstone for March?
The March birthstone is aquamarine. This breathtaking member of the beryl family — the same mineral group as emerald — captivates with its tranquil blue tones that range from the palest sky blue to the deep blue of a tropical sea. It is one of the most popular and wearable gemstones in the world.
The name "aquamarine" comes from the Latin aqua marina, meaning "water of the sea." Ancient mariners carried aquamarine talismans to ensure safe passage across stormy waters, believing the stone was a gift from Neptune, the Roman god of the sea. This maritime heritage makes aquamarine one of the most storied gemstones in history.
Today aquamarine is prized for its exceptional clarity, hardness, and versatility. Large, flawless crystals are relatively common, making aquamarine available in impressive sizes that are rare for other gemstones — and at accessible price points.

Pale Aquamarine
Light Sky Blue
The most common and affordable variety, with a delicate, icy blue that is perfect for everyday jewelry and large statement pieces.
Why Is Aquamarine the March Birthstone?
The connection between aquamarine and March is rooted in the ancient rhythm of the seasons. March heralds the arrival of spring — ice melts, rivers flow, and the sea begins to calm after winter storms. Aquamarine, with its water-inspired blue, perfectly captures this moment of renewal and awakening.
The modern birthstone list was officially standardized in 1912 by the American National Association of Jewelers (now Jewelers of America). They designated aquamarine as the modern March birthstone alongside the traditional bloodstone. Aquamarine's beauty, durability, and rich maritime symbolism made it an ideal choice to represent the month when winter gives way to spring.
Aquamarine connects to both March zodiac signs: Pisces, the water sign, resonates deeply with aquamarine's oceanic energy and intuitive qualities, while Aries appreciates its association with courage and bold new beginnings.
The History of Aquamarine
Aquamarine has been treasured since at least 480 BCE in ancient Greece. Roman fishermen called it the "sailor's stone" and carried it for protection and bountiful catches. They believed aquamarine was formed from sea water that had been blessed by Neptune, and that its power was strongest when submerged in ocean water beneath the light of a full moon.
During the Middle Ages, aquamarine was thought to be an effective antidote to poison — a serious concern for royalty and nobility. Crusaders wore aquamarine amulets for protection during battle and safe passage across stormy seas. It was also believed to reawaken the love of married couples and make the wearer invulnerable in legal disputes.
The Renaissance brought aquamarine into the courts of European kings and queens. One of the most famous aquamarines in history is the Dom Pedro, weighing approximately 10,363 carats — the largest faceted aquamarine in the world. This spectacular obelisk-shaped gem is now housed at the Smithsonian National Museum of Natural History in Washington, D.C.
Brazil has been the world's dominant source of fine aquamarine since the 18th century, particularly from the state of Minas Gerais. The discovery of exceptionally blue stones at the Santa Maria de Itabira mine established the "Santa Maria" designation for the finest, most intensely blue aquamarines.

Aquamarine is durable and well-suited for everyday wear, but a few precautions will keep it sparkling for generations:
Clean aquamarine jewelry with mild soap and warm water using a soft brush.

Steam cleaning is not recommended as sudden temperature changes can potentially damage the stone.
Store aquamarine jewelry separately from harder gemstones like diamonds to prevent scratching.

How to Choose Aquamarine Jewelry
When shopping for aquamarine jewelry, color is the most important factor. The most desirable stones display a medium-to-deep blue without noticeable green or gray tints. Because aquamarine often forms in large, clean crystals, you can find impressive sizes at reasonable prices — making it ideal for statement pieces.
- 1. Color first: Medium-deep blue with no visible green tint is the most valued. Deeper blues (Santa Maria quality) command higher prices.
- 2. Clarity: Fine aquamarine should be eye-clean. The gem naturally forms with excellent transparency.
- 3. Cut: Emerald cuts are classic for aquamarine and showcase its clarity. Oval and cushion cuts also work beautifully.
- 4. Setting: White gold, platinum, and silver complement aquamarine's cool blue tones. Yellow gold creates a striking contrast.
