Ethically Sourced Diamonds & Gems

Our unique business model allows us to provide the best and brightest GIA certified diamonds at very competitive prices. Each design is crafted within your budget and around the specific diamond or gem it will accompany resulting in a true custom design.


We specialize in ethically sourced 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.
