The hollow focal bead here is made with clear Murano glass and is decorated with whimsical dots in orange, yellow, red, lime, periwinkle and turquoise.  It measures 19mm wide (from hole to hole) and is about 21mm tall.  There are 5mm orange spacers on either side. 

The raised dot beads use the same colors as in the focal bead and measure approximately 10mm wide.

I've included some sterling heishe spacers and a couple of cracked Czech glass beads to finish the set off.
