Birthstones Silver SeriesThe Royal Canadian Mint has introduced a series that will appeal to anyone's tastes and interests: birthstones. Each month has a unique and beautiful birthstone associated with it, some of which are the emerald, sapphire, ruby and even diamond. These exquisitely produced coins would be a perfect gift for anyone. Each .9999 fine Silver coin features a gem-toned Swarovski crystal that replicates that month's birthstone. All coins in this series also have a limited mintage, adding further collectible appeal on top of the unique gemstone quality and exceptional design.
