The kanji "琉" is a phono-semantic compound (形声文字, けいせいもじ, *keisei moji*). ⚫︎ The semantic component is "玉" (たま, *tama*), meaning "gem" or "jewel," which provides the meaning related to precious stones. ⚫︎ The phonetic component is "㐬" (which is now considered an obsolete character and no longer used in standard Japanese), which originally gave a rough indication of the sound and possibly a secondary connotation. ⚫︎ Therefore, the character was created to represent a specific type of gem or the beauty associated with it. The combination of the components helped give a meaning and pronunciation.
