I hope this links back to the original question. If not this is a response to Kalyna's query. I have added a small diagram hope this helps, the only other thing I can think of is to just turn the whole pendant around so the pretty side shows?
"i put the jump ring(s) on the pendant then place the jump ring(s)with pendant on the chain, ribbon, etc. when the piece is worn the pendant thats hanging on the jumpring(s) is backwards. showing the back of the pendant instead of the pretty side!"S
