This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
璏 combines 王 (jade) with 彘, which likely contributes sound. The exact historical development is uncertain.
The jade radical 王 suggests a connection to precious stones, but without a clear meaning, treat the character as a rare jade-related shape.
For テイ, imagine a rare jade tablet (テイ) inscribed with the character 璏: tablet -> テイ, and the jade piece is mysterious.
