she is a variant
there are two versions of each rainbow pony
so far the only one we have not found two versions of is moonstone, i am sure she is out there though.
you can be sure she is a variant as my yellow symbol starshine is MOC
so it is not that the paint has rubbed away which is making the symbol look yellow.
nightlight ~ large vs small
raindrop ~ large vs small
skydancer ~ normal vs reversed
starshine ~ yellow vs gold
flutterbye ~ round vs square
moonstone ~ unknown!
there are pictures of each in the nirvana gallery
