Beadlet

A small bead or something resembling a small bead; a young or minor beadle.

From bead plus the diminutive suffix -let (as in 'leaflet,' 'booklet,' 'piglet'). The suffix -let in English creates small or minor versions of things. Applied to 'bead,' it means a tiny bead; applied metaphorically, it could mean a minor beadle.
