I originally thought about drilling holes in each side of the gold part, but then found a cuff bracelet I had bought years ago and never wore. It had black beading around the top and bottom, but I was able to easily remove the black beads and replace them with gold seed beads and black and clear crystals. Then, I simply glued the decorative part onto the cuff, using lots of E6000 glue.
Here's the finished piece.
Hope she likes it!
