and the meaning of jade does it bring good luck or something? thank you
DIFFERENT NECKLACE SAME SYMBOLS IN THE SAME ORDER ON IT

In Japanese the first character means good luck… I can’t tell what the second character is, but if the last is 寿 (sorry if that shows up as a square), then it means congratulatory. Most Japanese kanji characters were derived from the Chinese language and still have the same meaning.

Hope I helped!
