Description
On a pointed oval shield, 2 inches (5.08 cm) in width and 3 inches (7.62 cm) in height overall, and within an 1/8 inch (.32 cm) scarlet border, a landscape similar to that depicted in the coat of arms of Guam, with sky and sea in light blue, land areas green, palm tree with green foliage and brown trunk and in left foreground a canoe in brown with white sail.

Symbolism
The design is based on the coat of arms of Guam, showing land, sea and sky, with an ancient flying proa (canoe) approaching the beach near the mouth of the Agana River, and a palm tree in the foreground. The shape of the insignia is that of the sling stones used by the ancient Chamorros in hunting and fighting.
