Heriz rugs come from a town in the Azerbaijan Province of Iran. The most frequent Heriz or Herez rug layout has a geometric based medallion design, almost square in nature, which is also reflected in each corner of the field with a traditional palmette border, encased by minor borders in more detailed designs. The colors most often seen are reds, blues, ivory with small increments of gold. The look is tribal in nature as these rugs were originally woven with hand-spun wool and vegetable dyes. The more finely woven antique pieces, often in lighter tones have been designated Serapis.
