A bangle that does a quiet job well. The blue agate is calm rather than showy, so it lifts a work outfit without shouting and adds a little colour to an evening one.

Why the plating matters: the gold here is 3 micron 18ct plating over brass. Plating thickness is the figure that decides how a gold plated piece holds up, and Harfi states it plainly rather than leaving you to guess. It is also described as nickel free and lead free.

How it wears:

  • Slim enough to stack with finer bracelets
  • A 58mm width that sits comfortably on most wrists
  • Delicate detailing around the stone

Key facts:

  • Metal: 3 micron 18ct gold plating over brass
  • Stone: blue agate
  • Bangle width: 58mm
  • Nickel free and lead free
  • Guarantee: 1 year

Who it is for: anyone who likes a soft pop of blue, and anyone shopping for them. It works as a birthday, anniversary or thank-you gift, and it is easy to wear every day.

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.

Sabrina and Chris Sophelia Founders
