Makes no difference to the cost of the blanks.  A chunk of glass of type ABC
is the same, regardless of the grinding yet to be done on it.  Yes, the cost
of making those blanks into a finished lens element may/could/probably is
different.

I'm talking about when a camera company designs a lens it has different
glasses in it and it gets designed differently depending on which glass is
specified for each element.
