There are 3 Czech firepolished beads, the middle one just slightly bigger, and to add an accent I have used three 4mm beads on the last wrap for the middle bead. Those 3 tiny beads add some weight to the piece so it wouldn't turn when worn, so it's also a practical addition, apart from the bearing wire being slightly bent for the same reason.
The funny things about this picture is, that the wire I have used was BLACK steel wire, yet here it looks silver in colour. Note to self: have to do something about lighting for my photos...
