Iceland's coat of arms is a silver cross in a sky-blue field, with a bright red cross inside the silver cross. The arms of the cross shall extend to the rim of the shield on all four sides. The width of the cross shall be 2/9 of the width of the shield, but the red cross half as wide, at 1/9 of the width of the shield. The upper sections shall be squares and the lower sections the same width as the upper sections, but 1/3 longer.
The shield bearers are the four guardian spirits of Iceland as described in Heimskringla [by Snorri Sturluson, 13th century]: A bull on the right side of the shield; a giant, on the left; a vulture on the right above the bull; and a dragon on the left, above the giant.
The shield rests on a plate of columnar basalt.
Details of the four guardian spirits are given in the section on the history of the coat of arms.
