All Polar Bear Diamonds are 100% Canadian in origin, and have been mined, cut, and polished in Canada’s Northwest Territories. Like all Canadian diamonds, Polar Bear diamonds are held to the strictest ethical, environmental, and quality standards. Polar Bear diamonds also feature a laser inscription of a polar bear and a unique tracking code, which are invisible to the naked eye.http://farm4.static.flickr.com/3369/4575607131_db995f3a34_o.jpg
