The term 'with a diamond-shaped pattern' can be summarized by the word 'ARGYLE'. ARGYLE is a pattern consisting of diamonds, or lozenges, of varying sizes and colors arranged in a repeating pattern. It is most commonly associated with knitwear, such as socks and sweaters, but it is also used in other fabrics, wallpaper, and even tattoos. The term 'ARGYLE' is derived from the tartan of Clan Campbell of Argyll in western Scotland.
