Iced the cupcakes with pink icing, smoothed the icing, then put white sugar sprinkles. The sugar looks like diamonds maybe?
After these were in the cupcake holder I thought they needed some fairy magic wands, so it was back to the melted chocolate on wax paper. If you trail the ends to a point you can spike them right into the cupcakes.
Next time I think I will make the magic stars a bit pointier.
