Signet Jewelers, based in the U.K. is the world's largest specialty retail jeweler by sales, with stores in the US, UK, Republic of Ireland and Channel Islands. Approximately 78% of company sales are derived from the 12 different store brands operating in the U.S. They include Kay's, Jared's, JB Robinson, Marks & Morgan, and Belden Jewelers among others (all of which operate as Sterling divisions). Nearly all of these stores are located in malls where there is also a Kay store and target a similar customer. In many cases there are three or more Sterling stores competing under different names within a 300-yard radius of each other.
