Grauple are soft snowflake-like stuctures that bounce off hard surfaces. We usually call it snow pellets.
Small hail: Has a higher density than grauple, and are usually semitransparent and rounded, with diameters up to 1/5 inch. They consist partly of liquid water and sometimes have a frozen outer shell. Graupel transforms into small hail by the liquid water taken in through air capillaries in the ice framework.
Hailstones: Round stones of ice, with layers that look like an onion. Layers are formed during the stones and rise and fall within the storm cloud. During the a decent, the outer layer of ice melts slightly, and then re-freezes when updrafts carry the hail back up into freezing temperatures. The more clear the hailstone is, the slower the freezing process. The more opaque (milky) the hailstone is, the faster the freezing process.
