March Birthstone: Aquamarine
If you were born in March, Aquamarine is your birthstone. It is loved for its clear ocean blue colour and its easy elegance in everyday fine jewellery. It’s the sort of gemstone that feels quietly special, whether it’s set as a simple pendant, a refined pair of studs, or a centre stone that catches the light with a soft, aqua blue glow.
Where Aquamarine Gets Its Meaning
Aquamarine’s name comes from the Latin for ‘water of the sea’, and that connection has shaped its story for centuries. It has long been associated with calm, clarity and safe travel, particularly by those who lived and worked around the water. In folklore, it’s often described as a protective stone for sailors to bring smooth journeys, both literal and emotional.
In modern jewellery, that symbolism translates beautifully:
- For birthdays in March: a personal marker to celebrate you.
- For milestones: a fresh chapter stone, often chosen to represent clarity, courage, and new horizons.
- For couples: a gentle alternative to more traditional engagement rings, especially for someone drawn to softer colour rather than high-contrast sparkle.
If you’re buying aquamarine as a gift, the meaning is simple and wearable: peace, protection, and a little bit of ocean light you can keep close.
The Allure of Aquamarine
Aquamarine sits in the beryl family (the same family as emerald), but its personality is completely different. Where emerald is often lush and dramatic, aquamarine is clean, luminous, and airy.
The Colour That Makes It Unmistakable
Aquamarines range in colour from pale, icy blue through to deeper sea blue tones. Some stones even look slightly greenish-blue, which can look incredibly refined in daylight, especially when paired with yellow gold for warmth or platinum for a crisp, cool finish.
A quick styling guide:
- Pale aquamarine: elegant, minimal, and very ‘quiet luxury’. Stunning in simple, modern settings.
- Deeper blue aquamarine: more presence, more contrast, and a richer look in evening light.
- Green-blue tones: a softer, more organic feel, especially beautiful in vintage-inspired designs.
The Most Desirable Aquamarine Hue And Why It Costs More
When it comes to value, colour leads the conversation. In general, the stronger and purer the blue, the more desirable the aquamarine, and the higher the price tends to be.
The most sought-after hue is typically a deeper blue, slightly greenish blue, with moderate intensity. You may also hear the term ‘Santa Maria’ used for exceptionally vivid, saturated blue aquamarines, traditionally associated with Brazilian material. These richer blues are rarer, which is why they often command a premium compared to the more common pale sky blues.
A quick buyer’s tip: If two stones are the same size and clarity, the one with the richer, cleaner blue will usually be the more valuable choice.
How Aquamarine Catches Light
Aquamarine is known for its clarity, which means light moves through it with a glassy brightness like sunlight shimmering on water.
It’s particularly flattering in:
- Emerald cuts (clean lines, mirror-like flashes)
- Oval and pear shapes (a softer, romantic look)
- Cushion cuts (a little more vintage, very wearable)
The Metal Pairings That Elevate Aquamarine
Aquamarine is versatile, but the metal you choose changes the mood:
- 18ct yellow gold: warms the stone and gives it that effortless, heirloom feel.
- White gold or platinum: a cooler, icy look that makes the blue feel even cleaner.
- Rose gold: romantic and modern, especially with paler aquamarines.
Keep Aquamarine Looking Luminous for Years

A truly perfect aquamarine piece isn’t the one with the deepest blue on paper. It’s the one that catches the light the way you love, and feels like you every time you wear it.
