The kanji 珠 is a phono-semantic compound (形声文字, けいせいいもじ). The left side is the radical 玉 (ぎょく, gyoku), meaning "jade" or "jewel," indicating the meaning of the character. The right side is 朱 (しゅ, shu), which represents the sound. Thus, the character combines the meaning of jade/jewel with a phonetic component, representing the sound.
