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 to order

Our jewellers in Melbourne and Auckland make your ring to order, with quality checks at every step.Every stone comes from a certified supplier and is checked before it is set.Because we don't have showrooms or physical stores, our prices are much lower than at jewellers that do.
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.
