Polaris Diamond

The Gahcho Kue mine, in Canada, has yielded its largest diamond since operations began there more than four years ago. The 157.38 carat diamond, described as being of exceptional quality, will be sold later this month at a tender of special size diamond in Antwerp. Canadian miner Mountain Province Diamonds has named the diamond Polaris after the North Star, because of its rare natural blue fluorescence.
