The kanji 環 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is a radical, and the right side is a phonetic component. The radical on the left side is 王 which means "jade" or "gem." The right part of the character, 圜, provides the phonetic sound カン (kan), and also indicates a circular form. Thus, 環 originally referred to a ring made of jade, reflecting its preciousness and circular shape. The character then broadened to represent rings and circles in general.
