We specialize in diamonds that have received the highest grading from the Gemological Institute of America (G.I.A.) or the American Gem Society (A.G.S.). This is your assurance that your diamond has been deemed excellent cut, excellent symmetry, and excellent polish. Many diamond dealers refer to these as “ideal cut” , “Hearts and Arrows cut” and “triple excellent diamonds”. All of our diamonds are ethically sourced and we offer a wide selection of Canadian diamonds.

Owner Jim Omori has been in the Winnipeg Jewellery industry for over 30 years. He has enjoyed helping hundreds of couples find their perfect engagement and wedding rings. Jim also specializes in buying diamonds and custom jewellery design.
