How can I fix my chipped champagne glasses?

I have 3 or 4 champagne glasses that a heavy handed friend has chipped slightly on the rims. They are expensive lead crystal and I would like them repaired. Can anyone in reasonable distance of EX5 (Exeter) help?

I have today just filed the chipped rim of my cut glass bowl, using a set of diamond files that I bought for less than £5 delivered, on eBay!! I am an amateur and I must say the result is quite good! The chips are now smoothed out and no longer obvious. I suspect any professional mender will use diamond files anyway....
