fine quality jade
璦 refers specifically to fine quality jade, emphasizing its beauty and value as a precious stone.
璦 combines 王 (jade) with 愛, which likely contributes the sound アイ and may also suggest the idea of something cherished or beloved, fitting for fine jade.
The left side 王 (jade) tells you it's a type of jade, and the right side 愛 (love) suggests it's a jade so fine that it's loved and treasured.
For アイ, imagine an eye (アイ) made of fine jade, gleaming with beauty: eye -> アイ, and the jade is so clear you can see your reflection in it.
