Adhesives for Lalique crystal

This is a request from a colleague who does not have e-mail.

An artifacts conservator would like to know if there are any new
adhesives recommended for Lalique crystal.  Is there one which
matches its refractive index better than others?  I have already
searched the DistList archives and it appears that recommended
adhesives for glass have changed very little in the past ten or
fifteen years.  Many thanks for any information,
