Boy do I hate this particular job! What I do is separate the pile
first by eye, then further divide the smaller piles by either an inner
diameter measurement made with a micrometer (just inside between 2
diagonal prongs), or for the truly tiny ones, you can just plop what
you know is a .01 diamond onto a little cone of wax and just see how
it fits. Look in the back of your various catalogs for reference
sections and you’ll find diamond weights listed by diameters. Then you
can sort your boxes according to what they accomodate.
Personally, I’ve changed a lot of my findings storage into millimeter
based measurements. For bezels and stud earrings, it’s much easier.
Stuller findings even stamps the mm size into some of their products,
so all I need is a loupe to sort them.
