Birthstone Lore

According to astrology, aquamarine is aligned with the star sign of Pisces. and also considered the birthstone for March.

Aquamarines appear in many historical texts as a cure for ailments, including tired eyes, sore throats and of course, seasickness. Their colour is said to inspire creativity and courage.

In ancient times sailors would wear aquamarine amulets as protection from the stormy seas.

The blue cousin of the emerald

Aquamarine belongs to the beryl mineral family, which also includes emerald.

But while emeralds are green and fairly small, the aquamarine gets its blue hues from iron trace elements and occurs as big crystals.

Brazilian aquamarines are particularly large and have an almost glass-like purity.

Aquamarine Colour

Aquamarines can range from a clear light greenish-blue to an opaque dark blue.

Although crystals with intense blue colour are considered more valuable, most people seek light green-blue stones because of their unique, almost diamond-like sparkle.


From Princess Diana to the Oscars

Aquamarine has been used widely through the ages, from seamen’s talismans to haute jewellery.

It’s notably seen in British, Dutch and Danish crown jewellery and on Cate Blanchett‘s huge bib necklace at the 2015 Oscars.

Princess Diana had several aquamarine pieces and, most famously, wore an aquamarine ring instead of her blue sapphire engagement ring after becoming newly single in 1996.

Where on Earth?

The best aquamarines in the world come from Brazil, although the gem is also mined on the African and Asian continents.

The beautiful Brazilian provinces of Minas Gerais, Espirito Santo and Bahia have mines that produce the most vividly blue, pure beryl.

The Brazilian gem trade is conflict-free and the government restricts mechanised mining to protect the environment.

What to look for in aquamarine jewellery

Some gems are judged more by their colour, and some are more valued for their clarity.

With aquamarines, it’s important to strike a good balance between the two. Our gemmologist recommends:

  • No visible impurities
  • Vivid colour, whether lighter or darker
  • A skilful cut that makes it sparkle

Why buy aquamarine?

Aquamarine is a fantastic alternative to diamonds because of its showstopping sparkle and because it suits almost any complexion.

In terms of price, high-grade aquamarine is more expensive than blue topaz, but it’s not as dear as emeralds. This makes it affordable as well as beautiful.

In short, aquamarine is perfect for adding value, excitement and meaning to your jewellery collection, especially if it’s your birthstone.
