Aquamarine gets its name from the Latin for seawater, and the stone lives up to it: a clear, pale, watery blue that sits happily with a plain T-shirt and just as easily with a party dress. This necklace is a simple way to wear the March birthstone every day, without it feeling like occasion jewellery.
It also works as a gift. Give it for a March birthday, or to a bride as her something blue. Aquamarine has long stood for clarity, hope and loyalty, which is a decent thing to hand someone.
The key facts:
- Metal: 18ct gold vermeil (gold over sterling silver)
- Stone: natural aquamarine
- Chain length: 46cm
- Pendant size: 12 x 12mm
- Guarantee: 1 year
Why the vermeil matters: because the base is sterling silver rather than a cheaper metal, the gold finish sits on a more substantial foundation. That is the point of vermeil, and it is what you are paying the premium for over standard gold plating.
How it wears: at 46cm, the chain sits at collarbone level, and the 12 x 12mm pendant is large enough to show the stone's colour without dominating an outfit. It is easy to layer, or to wear on its own.
This one comes from Harfi, whose Sophelia jewellery is built around thoughtful gifting: the small, quiet reminders that someone is thinking of you.

About Harfi
At Sophelia, the bonds between loved ones have always meant everything to us. We believe the moments that matter most in life aren’t always the biggest ones – they’re also the small, quiet reminders that someone is thinking of you.
No matter where you are in the world, we’re here to help you show someone that they matter. Whether it’s a birthday, a graduation, or simply a thank you, it’s about making sure they feel seen, appreciated, and close to you – even from miles away.
At our heart, we’re a company built on sharing in joy. With two beautiful daughters at the centre of our world, we’ve always been reminded how powerful even the smallest gestures can be. A thoughtful gift isn’t just something you give – it’s a way of saying ”I’m with you, I’m proud of you, I’m thinking of you”. And your loved one can think of that every time they wear their jewellery.
That’s what Sophelia is about. Not just jewellery, but the feeling behind it – the connection it carries, and the moment it creates when it’s opened.
