璣 is a traditional Chinese hanzi, listed here under the keyword “pearl that is not quite round”. It is built from 王 (king) and 幾 (how many? how much?).
On KumiJi Glyph Explorer, open the parts search and type “king” + “how many? how much?”. 璣 is among the results, together with every other character containing the same shapes.
