Aquamarine: the Ultimate Jewellery Guide

Aquamarine, with its clear blue tones that seem to capture the spirit of the ocean, is one of the most calming and beautiful gemstones in the world. Its name comes from the Latin aqua marinus, meaning “water of the sea,” and it has long been treasured as a symbol of courage, clarity, and everlasting youth.

As the birthstone for March, aquamarine is both elegant and meaningful — perfect for jewellery that carries a sense of serenity and timeless style.

History & Symbolism of Aquamarine

Throughout history, aquamarine has been associated with the sea and protection. Ancient sailors believed it came from the treasure chests of mermaids and wore it as a talisman for safe passage across stormy waters. In the Middle Ages, it was thought to bring courage, clarity in decision-making, and harmony in relationships.

Today, aquamarine symbolises serenity, hope, and renewal. It is also the traditional gemstone for 19th wedding anniversaries and continues to be adored for its tranquil beauty.

Shades & Varieties

Aquamarine belongs to the beryl family, the same as emerald, but its appeal lies in its distinctive blue tones:

• Pale Sky Blue: Soft, delicate hues reminiscent of clear spring skies.

• Seafoam Blue-Green: Light tones with a hint of green, often romantic and dreamy.

• Deep Ocean Blue: Richer, more saturated stones — rarer and especially prized.

Most aquamarines on the market are heat-treated to enhance their blue tones, resulting in the vibrant colours so loved in fine jewellery.

Popular Aquamarine Jewellery Styles

Aquamarine’s clarity and colour make it perfect for both modern and vintage-inspired designs. Popular choices include:

• Aquamarine Solitaire Rings – A serene alternative to diamonds for engagement or statement rings.

• Aquamarine & Diamond Earrings – Sparkling combinations of cool blue and brilliance.

• Vintage Art Deco Pendants – Highlighting the stone’s geometric clarity.

• Aquamarine Tennis Bracelets – Elegant and contemporary.

• March Birthstone Jewellery – Personal and meaningful gifts.

Choosing a Quality Aquamarine

When buying aquamarine jewellery, consider the following:

• Colour: The most valuable stones display a vivid, medium-to-deep blue. Lighter shades are also beautiful and widely available.

• Clarity: Aquamarines are usually eye-clean, meaning they are free from visible inclusions.

• Cut: Step cuts like emerald and cushion shapes enhance clarity, while brilliant cuts maximise sparkle.

• Carat: Larger aquamarines are more common than many gemstones, making bold statement pieces surprisingly accessible.

Caring for Aquamarine Jewellery

Aquamarine is relatively durable, ranking 7.5 to 8 on the Mohs hardness scale. With the right care, it can remain radiant for generations.

Care Tips:

• Clean gently with warm water, mild soap, and a soft brush.

• Avoid harsh chemicals and prolonged exposure to heat.

• Store separately to prevent scratches from harder gemstones.

• Remove before heavy physical activity to protect both the stone and setting.
