Birthstone or Favorite Stone?

We've been shipping lots of Balance Bead Birthstone sets lately, and it occurred to me that I'm not 100% sure whether our customers are picking their actual birthstones or just their favorite colors. My crystal birthstone color would be pink (October) but I'm really loving a set I shipped out today: silver with dark green crystal (May). Unfortunately, the picture doesn't quite capture the sparkle of the crystal. So pretty! I try not to steal from my own stock but I just may have to make an extra set for myself!
