This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
琑 combines 王 (jade) with 肖, which likely contributes the sound. The exact historical development is uncertain.
The left side 王 suggests jade or a precious stone, while the right side 肖 provides the sound. Without a clear meaning, picture a small, delicate jade piece: ちいさ.い (small) and くさり (chain) hint at a tiny linked ornament.
For サ, imagine a small jade pendant shaped like a saucer: saucer -> サ, and the tiny jade piece hangs from a chain.
