The kanji 圭 is a *会意文字 (kaii moji)*, a compound ideogram. It is formed by combining two identical characters 土 (tsuchi), meaning "earth" or "soil." The doubling of 土 might have originally represented a piece of earth carved into a square, a shape associated with jade carving in ancient China, and thus representing a piece of jade with sharp angles.
