Identify this story

I’m looking for the name of a vintage science fiction story. While a scientist is looking through a powerful microscope he discovers a beautiful woman living in a microscopic world contained in a drop of water, he then falls in love with her.
Also, is this story currently in print as part of a collection?

I don’t think this is it but http://etext.lib.virginia.edu/cgibin/browse-mixed?id=ObrDiam&tag=public&images=images/modeng&data=/texts/english/modeng/parsed

It sounds much like Ray Palmer’s The Girl in the Golden Atom, certainly a classic. It’s available in a number of places. The one I have is Under the Moons of Mars: Science Fiction in the Munsey Magazines edited by Sam Moscowitz.

But I think there really may be one in which a scientist sees a girl in a drop of water, too. I seem to have a vague recollection of it. If so, I can’t recall the story title, or its author.

I believe you’re looking for The Diamond Lens by Fitz-James O’Brien.

Dijon’s right. It just took the name o the author to jog my memory.

My memory’s obvioult shot – it as Ray Cummings, not the ever-paranoid Ray Palmer, who wrote The Girl in the Golden Atom and its sequels.
