About Us

Omori Diamonds is a father & son jewellery design team and diamond importer based in Winnipeg, Manitoba. Our goal is to bridge the gap between time tested art of custom craftsmanship, and the modern jewellery landscape, bringing you an exceptional personalized experience. This is done from the intimate setting of our comfortable office, free from the high pressure and overhead of a retail store. We invite you to book your private appointment and to come and see why so many couples have chosen us to create their dream ring.

A Brief History

Jim Omori began his career as a jeweller and designer over 30 years ago, when he worked as the manager for a prestigious fine jewellery 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.

Into The Future

After a successful career as a designer and general manager in the Winnipeg jewellery industry, Jim and his son Chris formed Omori Diamonds by combining Jim’s expertise in artisan craftsmanship and Chris’s knowledge of the modern business landscape. It is our goal to provide you with a level of quality and creativity worthy of your most precious celebrations and memories.

Chris Omori


Chris Omori is Jim’s son. He has grown up around the jewellery business and is currently apprenticing under his father to learn the skills of the trade. While Jim first learned the trade through the traditional skills of wax carving and hand sketching, Chris has taken full advantage of the advances in modern design technology and has been doing design work using CAD (computer aided design). Outside of the business Chris has a passion for music, art and travel.

Omori Diamonds Conflict-Free Diamond Policy

Omori Diamonds has a zero tolerance policy towards conflict diamonds. We deal only with the industry’s largest and most respected diamond brokers who follow the Kimberly Process. The Kimberly Process is an international process adopted by the United Nations to track the flow of rough diamonds from the mine, assuring they are conflict free. The American and Canadian Custom Services actively enforce the Kimberly Process requirements.

All of our custom manufacturing is made using gold from Canada and follows the strictest guidelines for mining.
