Answer:
I have two suggestions for you, Michelle.
1. Add a piece of pattern wire to the center of the frame bundle;
2. Use a harness, such as the one shown on the heart below, but change it just a bit. Instead of using just 2 wires, use 4 and bring the center 2 up across the front of the stone, and the other 2 on the sides as normal. Make the bail and embellish as desired.
