I have a USB microscope that's very helpful -- much better than the jeweler's loupe I have.

They exaggerate the magnification, but this is basically what it looks like with a 1-2mm edge bevel:

3D,

Nice looking USB microscope. Does it happen to have a fine focus control?

It has fine focus control of sorts.  The black knob on the back adjusts the height (zoom and course focus) while the gray ring on the barrel does finer focus.  It's a bit fiddly in practice, but not bad.
