Oh don't control yourself over buying what you want! If you want to buy more birthstones, you should keep your bells, plus there is going to be a new birthstone, the April one !
If I'm honest, I'm only interested in getting my own birthstone (July birthstone) ~ I guess you could say I bought it for no reasonexcept for the fact that the seller wanted to change their username and I felt bad for them hehe.
you've started a collection, so once you started you gotta complete it ?___?
Naaw I only have 3 birthstonesI'd be more bothered if I had all of the ones that have been available so far hehe.
