Sorry about that Cathy but the advertising item was sold so I can't trace the new owner. Please delete the photo.
Thanks to all who have responded. The current "Diamond Crystal" is based in Teheran, Iran - but I read recently that several Bohemian glass companies had beeen bought by Iranians so maybe this is new instar of the older company. I intend to email them and If I get a positive response I will post to that effect.
