Custom Engagement Rings in Toronto

At Jacob Mercari, we create custom engagement rings designed around your vision. Whether you have a specific style in mind or need help bringing your idea to life, our team guides you through every step of the design process.

Each ring is crafted using premium materials, including lab-grown and natural diamonds, 14K and 18K gold, platinum, and fine gemstones. From our Toronto studio, we serve clients across the Greater Toronto Area, Canada, and the United States through both in-person and virtual consultations.

Step 1

Consultation

For your consultation, we can meet with you in person or online at our Toronto Studio.

If you are unsure, please reach out to us. We can start with a quick chat and then work from there.

Our design team will work closely with you to bring your vision for a custom engagement ring or jewellery piece to life. We like to make the consultation fun and easy. Bring any ideas or images that you have saved up. We will discuss your ideas in detail, mentioning any pros or cons to the design, so you have all the information on a given design before moving forward.

Step 2

Computer Model Design

We will create a digital design for your idea. You are free to make any changes you see fit. We want you to make the design exactly as you want. We do not put pressure or rush the process.

Step 3

Manufacturing

We manufacture your ring using your chosen metal alloy and diamonds or gemstones, ensuring it matches the 3D rendering exactly. Once the ring is cast, our skilled craftsmen will carefully set the diamonds and polish the jewellery. Quality is of utmost importance. Our custom engagement rings and jewellery are made in Toronto. This ensures we can tightly control the quality of manufacturing.

Step 4

Presentation

After the custom piece is complete and quality has been checked, we will have it appraised by a third party. You are welcome to pick up in person in Toronto, or we can ship via FedEx insured delivery.
