clarity, sound of jewels
瓏 centers on the clear, bright quality of polished jade or gems, especially the luminous clarity and the delicate ringing sound they make when struck together.
瓏 combines 王 (jade) with 龍 (dragon), which likely provides the sound. The character originally referred to a type of jade used in ceremonies, associated with clarity and resonant sound.
The left side 王 (jade) shows this is about precious stones, and the right side 龍 (dragon) suggests something majestic. Imagine a dragon's hoard of perfectly clear jade pieces that ring like tiny bells when they touch.
For ロウ, picture a row of clear jade pendants hanging in a line: row -> ロウ, and each one chimes with a pure, bright sound.
