I know these cut-to-clear vases with gilding and enamel paint are in current production in the Czech republic (or in Russia, Hungary or Poland). I see these (mostly with a white top layer) quite regularly and find they are remarkably cheap for such an intricate piece of work. You can normally pick these up for 30 to 50 UKPs.
Now I do not think they were made with intent to deceive - but the auction house describing it as "late 19th early 20th Bohemian" had it wrong. The
style is late 19th - but the production continues to this day.
As for wear on the stand ring ("soft scratch") this can occur in as litttle as 10, 15 years so it is an indication of
some age - but it does not have to be a
great age.
Moser is just one of the many glass makers who worked in this style - but there are many others.
http://www.crystal-treasury.com/ has similar items, I believe.
