Apparently they are Pearl, Alexandrite and Moonstone.
Did you know we share the same birthstone, that's so cool!For those, who have no clue what is a birthstone and how do you know your birthstone?
Your birthstone is the one that matches the month you were born in and the gem that's match with it is your birthstone!
For example: My birthday is in October, so my birthstone is Opal.
What's yours?
