If you are considering a custom engagement ring, one of your first questions is probably: how much will it cost?

In Toronto, the price of a custom engagement ring can vary considerably. A simple design with a lab-grown diamond may begin in the lower thousands, while a detailed ring with a larger natural diamond can cost significantly more. The final price depends primarily on the centre stone, setting, precious metal and complexity of the design.

At Jacob Mercari, we believe pricing should feel clear not mysterious. We work with each client’s style, priorities and budget to create a ring that feels personal while providing guidance on where their money will have the greatest visual and practical impact.

What Is the Average Cost of a Custom Engagement Ring in Toronto?

As a general guide, many custom engagement rings fall within the following ranges:

Custom engagement ring Approximate starting range (CAD)
Simple 14K gold setting, without a centre stone $1,050–$2,000+
Detailed pavé, hidden-halo or multi-stone setting, without a centre stone $1,800–$3,000+
Complete ring with a lab-grown diamond Approximately $2,000–$5,000+
Complete ring with a natural diamond Approximately $4,000–$10,000+

 

These figures are intended as general examples rather than fixed quotes. Diamond quality, carat weight, metal prices and design details can all affect the final cost. Larger stones, rare specifications and highly intricate settings may fall above these ranges.

A private consultation allows us to provide a more accurate estimate based on the ring you actually want to create.

What Determines the Price of a Custom Engagement Ring?

1. The Centre Stone

The centre diamond or gemstone is often the largest part of the budget. Its price is influenced by several factors, including:

  • Whether it is a lab-grown diamond, natural diamond or coloured gemstone
  • Carat weight
  • Shape
  • Cut quality
  • Colour and clarity
  • Certification
  • Rarity and availability

Two diamonds of the same carat weight can have very different prices. A well-chosen diamond does not simply look good on paper; its proportions, brilliance and overall appearance should work beautifully in the finished ring.

At Jacob Mercari, clients can compare certified lab-grown diamonds and natural diamonds, or choose a sapphire, ruby, emerald or another fine gemstone.

2. Lab-Grown vs. Natural Diamonds

Both lab-grown and natural diamonds are real diamonds with the same fundamental physical and optical properties, but their prices are very different.

Lab-grown diamonds generally make it possible to choose a larger or higher-quality stone for a lower price than a comparable natural diamond. This can leave more room in the budget for a detailed setting, larger carat weight or premium colour and clarity.

Natural diamonds typically cost more because of their natural origin, rarity and market value. For clients drawn to tradition and natural formation, a carefully selected natural diamond can be an important part of the ring’s meaning.

There is no single right choice. The best option is the one that reflects your preferences, priorities and budget.

3. The Engagement Ring Setting

A refined solitaire will usually cost less than a design with pavé diamonds, a hidden halo, side stones or intricate metalwork.

Common setting styles include:

  • Solitaire
  • Cathedral
  • Bezel
  • Hidden halo
  • Pavé band
  • Three-stone
  • Halo
  • Toi et moi
  • Custom sculptural or nature-inspired designs

The amount of gold or platinum, number of accent stones and labour required all contribute to the price. You can explore our engagement ring settings to compare styles and starting prices.

4. The Precious Metal

The metal you choose also affects the total cost. Jacob Mercari custom engagement rings can be created in 14K or 18K white, yellow or rose gold, as well as platinum.

Fourteen-karat gold is a popular choice because it combines beauty, durability and value. Eighteen-karat gold contains a higher percentage of pure gold and has a richer colour, while platinum offers a naturally white appearance and substantial feel. The amount of metal required will also matter; a wide band generally costs more than a delicate one.

5. Design Complexity

A custom ring does not need to be elaborate. Some of the most beautiful custom designs are clean, timeless solitaires created with carefully considered proportions.

However, features such as hand-applied details, an intricate gallery, custom diamond layouts, engraving, multiple gemstones or a fitted wedding band require additional design and production work. We explain these costs before manufacturing begins so you can decide which details matter most.

Does Custom Design Always Cost More?

Not necessarily.

Custom design means the ring is created around your chosen centre stone, preferred metal, finger size, lifestyle and design priorities. It does not automatically mean adding expensive details.

In many cases, customizing an existing setting is a practical way to achieve a personal result while controlling the budget. A band width can be adjusted, prongs refined, a hidden halo added or removed, or a setting adapted for a different diamond shape.

The benefit of custom design is control. Instead of paying for features you do not value, you can direct the budget toward the details that matter most to you.

How Can You Keep a Custom Ring Within Budget?

Start by sharing a comfortable budget range with your jeweller. This allows the design and diamond search to be approached realistically from the beginning.

Several thoughtful choices can make a meaningful difference:

  • Choose a lab-grown diamond if size and brilliance are the highest priorities.
  • Compare several diamond shapes, since pricing can vary by shape.
  • Consider a stone just below a full-carat milestone, such as 1.40 instead of 1.50 carats.
  • Focus on cut and overall appearance rather than automatically choosing the highest colour and clarity grades.
  • Select 14K gold instead of 18K gold or platinum.
  • Begin with a clean solitaire and add detail through a wedding band later.
  • Prioritize the features that are most visible and meaningful to you.

An experienced jeweller can help identify where a difference in price will be noticeable—and where it may not be.

What Is Included With a Jacob Mercari Custom Engagement Ring?

The value of a custom ring extends beyond the materials alone. Your Jacob Mercari experience includes guidance through diamond or gemstone selection, design development, a detailed CAD preview and careful production of the finished piece.

Custom engagement rings also include:

  • An independent third-party appraisal
  • Diamond certification where applicable
  • Complimentary lifetime sizing

How Does the Custom Engagement Ring Process Work?

The process begins with a conversation about your ideas, budget, timeline and preferred centre stone. You do not need to arrive with every detail decided. Inspiration photos, saved designs or even a simple description are enough to begin.

After the direction is established, we help you select a diamond or gemstone and create a detailed CAD rendering of the ring. You will be able to review its proportions and design details before production begins. Once approved, the ring is manufactured, carefully set, polished and inspected before its independent appraisal and final presentation.
