yes same. I really do want birthstones, but I haven't kept track of when they aged up. I turned aging up off so I usually batch age them up according to stage changes or new worlds coming to the game. I wish the game had an update for that anniversary's and tied in birthstones to the the sims infomation panel. I will definitely used my birthstone for my sim self, and she is wearing aquamarine stone earnings in this look as my current profile photo,as I thought of it, while making her. I but will make her jewelry in what ever stones she has collected, as well, she has quite a collection.
I do think birthstones add luck in real life and right before the pandemic I started collecting jewelry again, in my stone. I want to see if I can make similar in game.
