emperor's seal
璽 centers on the emperor's personal seal, a physical mark of ultimate authority and authenticity.
璽 combines 爾 (originally a phonetic element) with 玉 (jade), reflecting the material of the imperial seal. The exact historical development of 爾's role is uncertain.
The top 爾 looks like a complex official emblem, and the bottom 玉 is jade. Picture an intricately carved jade stamp that only the emperor can use.
For ジ, imagine the emperor pressing his seal with a soft 'ji' sound as it stamps the paper: the sound 'ji' cues ジ.
