Or for a more "gut feeling" approach...
THUMBNAIL: fits in a 1.25 inch square "Perky box" (invented by Willard Perkins to hold small rocks)
MINIATURE: simply a rock that can be squeezed into a 2-inch square box
CABINET: A hand-sized specimen larger than 4 inches (10 cm ) in a dimension
SMALL CABINET: in between Miniature and Cabinet...you can hold it in your palm
TOENAIL: a new division in Tucson show judging - basically they are just barely too big to squeeze in a tn box
