Three Step Process

Let's Talk

We start with a conversation — your budget, your ideas, your vision. No pressure, no commitment. We'll brainstorm together and put together a general quote based on what you're thinking.

Design Deposit & CAD

Once you're ready to move forward, a small $150–200 deposit secures your design. This covers our time and gets the process started. We'll build a detailed CAD rendering of your ring and send it to you for review. Adjustments are welcome — we don't move forward until you love it.

Final Price, Full Build

With your design approved, we give you the final price, collect payment, and get to work. Your ring is handcrafted at our bench in Canada from start to finish. The deposit goes toward your final balance — so nothing is wasted.

What others are saying

I got my wife's engagement ring from my boy Jeff at Mad Minerals. The details and dedication to his art is still getting noticed to this day. Amazing service and first class work.

Jeff did an amazing job with both mine and my husbands rings! Jeff and his team do incredible work and would recommend then 1000x over!

Jeff absolutely crushed it. The rings turned out unbelievable and most importantly my wife adores them. Couldn't be happier how it all turned out - he took care of everything from start to finish.

Jeff was great from start to finish. I have had a struggle finding a reliable and trustworthy jeweller in Montreal and he is the best i've seen. I've recommended several to him as well. Thank you Jeff and Mad Minerals.
