Topic: Fine cut crystal perfume bottle, silver top, possibly American

[chilternhills]

I bought this charming perfume bottle yesterday, just because I liked it. It oozes quality in the cut crystal - it's very fine. I hope the pictures show that. The bottom of the square base is star cut. The base is also beveled (narrower toward the bottom) and stepped. The silver top is marked 'Sterling Silver', which suggests it's not English. The person I bought it from thought American.

Any ideas as to its manufacture? The flask measures 9.2 cm to the base of the silver top. The base is 4 cm square at its maximum size. The sprayer is a pump action mechanism, i.e. there was no separate puffer.

Thanks for your help.
