Our Story

A Brief History

Jim Omori began his career as a jeweller over 30 years ago, when he worked as the manager for a prestigious fine jewelry shop on the West Coast of Canada. During this time he was mentored by some of Canada’s top designers and learned many of the techniques and skills which he still uses to this day. Over the next decades, Jim developed a great reputation as an award winning designer and jeweller and made many lifelong friendships with other well respected gemologists and designers in the industry.

Bridging the gap

After a successful career as a designer and general manager in the Winnipeg jewelry industry, Jim and his son Chris formed Omori Diamonds inc. by combining Jim’s expertise in artisan craftsmanship and Chris’s knowledge of the modern business landscape. They have since grown drastically, creating hundreds of custom design projects for clients in Winnipeg and across Canada.
