Canadians have the highest diamond engagement ring acquisition rate in the world at 85 percent. The jewelry market is broken into two retail categories; fine jewelry (with precious metals and gems) and costume jewelry. The Canadian jewelry market has hit or exceeded projected growth expectations for the previous three years. Primary purchasers of both fine and costume jewelry are females between the ages of 20 and 50.  In 2006, over US$2 billion was spent by Canadian consumers on jewelry.
