I like the idea of using a variable to track whether the loop has to restart. As long as there's only two possibilities (valid and invalid), it's common to use a boolean in this role, something like:

valid_symbol = false

while !valid_symbol do
  # ...

Watch your spacing here. Good style is usually to put a space on either side of an equals sign or operator, like n2 = gets.chomp
