But some people will also sell you Moon Glass.
Is it the next best thing? No, it's better and whilst it is not from the moon the price may actually be not too dissimilar, gram for gram, to a bit of old moon rock.
And it is fabulous and glamorous and very appropriate for Boodles where it has been used in their new showroom at The Savoy designed by Eva Jiricna (who else) with the able assistance of Luke Desborough as Project Architect.
Specification of the 'Moon Glass' as supplied and installed by Techniques Transparentes is as follows:
12mm thick, optiwhite glass, sandblasted on the rear to give a lunar landscape appearance, with a white gold leaf ( 9 cts) applied to the sandblasting
