Navajo Crystal storm pattern rugs have a distinctive design that emerged from the now-defunct Crystal Trading Post starting at the turn of the 20th century. The trading post’s proprietor, J.B. Moore, marketed Navajo rugs to buyers in the eastern part of the United States with mail-order catalogs (one in 1903 and one in 1911). The storm pattern was one of the rug designs that could be ordered and quickly became popular with collectors. Navajo storm pattern rugs are still made to this day.
Storm patterns are characterized by a large central rectangle with four smaller rectangles in each corner. The small rectangles are connected to the central rectangle with zig-zag lines. While the precise origin of the Navajo storm rug pattern is unknown, it was the weavers at Crystal that made this pattern the sought-after Navajo rugs that they are today.
