How to Design a Custom Engagement Ring: A Step-by-Step Guide

An engagement ring is one of the most significant pieces of jewellery you will ever purchase. It marks a moment that matters and for many couples, a ring pulled from a display case simply does not feel like enough. That is why more Canadians are choosing to go custom.

At Jacob Mercari, we work with clients from Toronto and across Canada to create custom engagement rings that are as individual as the people wearing them. In this guide, we walk you through exactly what the custom design process looks like — so you know what to expect before you ever book a consultation.

Why Choose a Custom Engagement Ring?

The jewellery industry has long relied on mass production thousands of identical rings manufactured at scale and distributed across chain retailers. For some buyers, that works. But if you are proposing to someone who values individuality, craftsmanship, or meaning, a custom ring offers something fundamentally different.

A custom engagement ring means:

The design is entirely yours — no compromises on style, metal, or stone
You control the quality at every stage of the process
The ring carries a story — your story — from the very first sketch
You often get more for your budget than you would at a retail chain

The Jacob Mercari Custom Design Process

We have refined our process over years of working with clients at every stage of their jewellery journey. Here is what designing a custom ring with us actually looks like.

Step 1: The Discovery Consultation

Every custom ring starts with a conversation. In your initial consultation available in person in Toronto or virtually for clients across Canada — we listen. We ask about your partner's style, your budget, any inspiration pieces you have gathered, and what the ring needs to feel like when they wear it every day.

There are no wrong answers and no pressure. This session is purely about understanding what you are looking for before anything goes on paper.

Step 2: Design and Concept Development

After the consultation, our team develops design concepts based on your brief. You will receive detailed renderings showing how the ring will look from multiple angles, including metal choice, stone placement, and any custom details, engraving, milgrain edging, unique prong styles, and more.

We revise until the design is exactly right. You will never be asked to approve something you are not fully confident in.

Step 3: Stone Selection

Once the design is approved, we source the centre stone. Whether you are looking for a natural diamond, a lab-grown diamond, or a coloured gemstone, we present you with hand-selected options that fit your design and budget.

We walk you through the 4Cs — cut, colour, clarity, and carat — in plain language so you can make an informed decision, not just an emotional one.

Step 4: Crafting the Ring

With design and stone confirmed, crafting begins. Our craftspeople build your ring to precise specifications using time-honoured techniques and modern precision tools. The process typically takes three to five weeks, and we keep you updated throughout.

Step 5: Final Review and Delivery

Before your ring leaves our hands, it goes through a thorough quality review. When you receive it whether picked up in Toronto or delivered securely to your door anywhere in Canada, you will know it was made specifically for the moment you have planned.

Common Questions About Custom Engagement Rings

Is a custom ring more expensive than a retail ring?

Not necessarily. When you design custom, you are paying for the ring you actually want not a margin markup on something close. Many clients find they get better craftsmanship and a more meaningful piece at a comparable or lower price than comparable retail options.

How long does the process take?

From first consultation to delivery, the process typically takes six to eight weeks. If you have a specific date in mind, we recommend starting the conversation as early as possible — ideally at least three months before you plan to propose.

Do I need to know what I want before the consultation?

No. Many of our clients come in with nothing more than a sense of their partner's personality and a rough budget. That is completely fine. Part of our role is to help you discover what the right ring looks like guiding you through styles, metals, and stones until something clicks.

Can I work with Jacob Mercari if I am not in Toronto?

Yes. We work with clients across Canada. Virtual consultations allow us to walk through designs, share stone options, and review renderings together exactly as we would in person. Completed rings are shipped securely and fully insured to any Canadian address.

What to Bring to Your First Consultation

You do not need to arrive prepared with a complete vision. But if you have any of the following, bring them along they help us understand your direction quickly:

Photos of rings you love (Instagram saves, Pinterest boards, or screenshots are all useful)
A sense of your partner's everyday style — classic, modern, minimal, vintage?
A comfortable budget range (you do not need an exact number)
Any stones or family heirlooms you are considering incorporating
Your timeline — specifically when you hope to propose
