Where are you starting?
Three ways to find the one
Most people arrive knowing almost nothing about diamonds. That's completely normal — start wherever feels comfortable.
I have no idea where to start
Come in and look at real stones with no pressure. We'll walk you through cut, colour, and carat in plain language — and show you what your budget actually buys.
Book a guided visitI want to see the collection
Solitaires, halos, three-stone, and hidden halo settings — all made in our Montreal atelier, available in white gold, yellow gold, and platinum.

A sketch, a screenshot, an heirloom stone you want reset. Bring it in — custom is what our workshop was built for.

Most jewellers order your ring. We make it.
Walk into most jewellery stores and the ring you choose gets ordered from a supplier catalogue — often the same one their competitor down the street uses.
Ours are designed, cast, and hand-set in our own workshop by jewellers who have been doing this for three decades. When you ask for a slightly thinner band or a lower setting, the answer is yes — because the bench is twenty feet away.
What actually happens
From first conversation to the moment you ask
4
We talk
In person or by phone. Tell us the style, the budget, and the date you're aiming for. No sales pitch.
5
You see the stones
We lay out hand-selected diamonds — natural and lab-grown — side by side so you can compare with your own eyes.
6
We design it
A 3D render before anything is cast, so you approve the exact proportions before we begin.
7
We make it
Cast, set, and finished by hand in our workshop. Typically two to three weeks, faster if you need it.
In their words
They said yes

Come see them in person
Photos can only tell you so much. Book a private appointment and we'll show you stones at several carat weights, on an actual hand, so you can see the difference for yourself.
