Cut a length of chain approx. 6". Attach a jumpring to either end of the chain and link this to either side of your floral ring charm. 

Find the central link of this section of chain and cut it. Check how this fits around your wrist and trim it accordingly if needs be. Next, attach a lobster clasp to one end of the chain and a single jumpring to the other side. 

To the loop on top of the floral ring charm, attach a jumpring. 
Take a headpin and trim off the nail tip end. Loop one side of the pin. (See this tutorial on how to turn a loop - here)
Thread on one of your amethyst coin beads. 
Trim and loop the other side of the pin just above the bead. 
Attach one of these loops to the jumpring on your ring charm.

Measure a length of chain long enough to go from approx. the centre of your hand, around your middle finger and back to the centre of your hand.
Connect the two ends of this length of chain with a jumpring.
Connect the jumpring to the other loop on your pin with the amethyst coin bead. 

To finish your bracelet, thread your selection of beads onto individual headpins. Trim and loop the pins and attach them at different points on your bracelet.
