Over the past several years, a quiet revolution has been taking place in the world of fine jewellery. Canadians, known for being thoughtful, values-driven consumers, are increasingly turning to lab-grown diamonds — not as a compromise, but as a deliberate, informed choice. Sales of lab-grown diamonds have surged across the country, and the reasons go far beyond price.

Here's exactly how lab-grown diamonds are graded, which certifications matter, and what to look for when reviewing a diamond report.

Whether you’re shopping for yourself or searching for the perfect gift, knowing what to look for can make all the difference.

Here are the most common mistakes people make when buying diamond jewelry online—and how to avoid them.

At Jacob Mercari, we love natural diamonds for exactly that reason. They are not just stones. They are stories you can wear.

When it comes to meaningful gifts, few things carry the same emotional weight as diamond jewelry. Whether it’s a birthday, anniversary, holiday, milestone, or a “just because” moment, diamonds have become one of the most powerful symbols of love, commitment, and lasting connection.

At Jacob Mercari, we love sapphires because they combine timeless beauty with everyday practicality. Whether you are designing a custom ring, choosing a meaningful pendant, or looking for a colourful gemstone piece you can wear daily, sapphire is always a beautiful choice.

At Jacob Mercari, we’ve built our studio on the belief that the most meaningful jewellery tells a story. Birthstones are one of the oldest ways to do exactly that. Whether you’re designing a custom engagement ring, a gift for someone you love, or a personal piece for yourself, choosing a gemstone tied to your birth month adds a layer of intention that a diamond alone simply cannot replicate.
