Thick band engagement rings

Chunky engagement rings on our 3mm band, the widest we make in gold or platinum, so the band carries as much of the look as the stone. Every ring opens at 3mm, and you can choose 2.5mm or 2mm before you order.

How wide is a 3mm band?

3mm is the widest band we make, half as wide again as our standard 2mm, and at that width the band stops framing the stone and becomes part of the look. It carries the most metal of any width, holds its shape through decades of daily wear, and balances a centre stone of 2 carats or more.

Our approach

We have a very hands-on bespoke process. You'll work with Brie to design and craft your dream ring. We make sure that this experience feels very special and tailored to you.

01

Consultation

Start from one of our designs, bring us one you found elsewhere, or design something new with us.We do it by video call or email, whichever suits you.You work with Brie directly from the first conversation.
02

Unlimited revisions

We change the design as many times as it takes for you to love it.Then we render it in CAD so you can see your exact ring before it is made.Revisions stay unlimited at that stage too.
03

Made by hand

Our master jewellers, setters and polishers build your ring by hand, with quality checks at every step.Every stone comes from a certified premium supplier and is hand checked before it is set.Because we are a boutique studio, you will not find this quality at our prices anywhere in Australia.
04

Insured, fast shipping

Your ring ships fully insured and tracked.It arrives boxed and presented, ready for the moment you have planned.We keep you updated from the first consultation all the way through to the end.

Create your custom ring

We design and craft your dream ring specifically for you. You'll work with Brie to pick your stone, design your setting, and any other details that really make it your own. We can't wait to make your special moment come true.
