Prepare a tool by purchasing sandpaper of about 600 grit or finer. This can found in automotive stores as well as furniture finishing departments.
Wet a small piece of sandpaper so that it is flexible enough to wrap smoothly around a cylindrical tool such as a pencil or pen. Fasten with a small amount of tape.
Use the tool to slowly file the chip in the crystal, taking great care not to use too much pressure. Focus on any rough or sharp places. Be patient, but don't overcorrect. The finished product is not likely to be perfect, but the goal is to make the stemware safe to use. If the repair is perfect, the value of the piece will not be affected.
Purchase a Crystal Saver diamond file from a website or dealer if the repair with sandpaper is not satisfactory. The Crystal Saver is a rounded file designed to smooth the edges of a chipped glass. It may or may not produce perfect results.
