Clear Whites on the Nails

There was a girl with an Italian last name with smooth black hair, blue eyes, and freckles.  I remember her nails were see-through on the part that usually is grown in white.  Then when the daughter of the music people I mentioned just now sang in front of the classroom for a master class, meaning people getting together to present what they've learned with a teacher and audience of classmates.  I could see that her nails were longer but see through.
