Fine Jewellery Guides & Inspiration | Jacob Mercari

Lab-grown diamonds are real diamonds. They have the same chemical, physical, and optical properties as natural diamonds but are created in advanced laboratories instead of forming underground over billions of years.

You have done the research. You know the general landscape the cuts, the settings, the budgets. Now comes the most important step: making the right choice for the person you love and the life you are building together. This guide is written for exactly where you are thoughtful, informed, and ready to decide with confidence.

Discover the newest engagement ring style designed for everyday wear and unforgettable sparkle. Our Half Bezel Engagement Ring Collection features sleek, sculptural settings that partially frame the center stone for a clean, contemporary look—while keeping the diamond beautifully secure.

At Jacob Mercari, we specialize in both expertly designed ready-to-ship engagement rings and fully custom creations, ensuring every couple finds a ring that feels truly personal.

Jacob Mercari is proud to unveil our latest release: The Contour Collection an intentional exploration of silhouette, geometry, and architectural jewelry design.

This collection was created for those who love a piece that feels modern yet timeless, bold yet refined. It’s not just about brilliance, it’s about the form that brilliance takes.

In the world of fine jewelry, there is a growing movement toward "Quiet Luxury" pieces that don't need to shout to be noticed. For many of our clients at Jacob Mercari, in Toronto, the goal isn't just to have the biggest diamond in the room; it’s to have a ring that reveals its beauty in layers.
