The jeweler could make the cage flat on the back to sit flat on the skin but curve the wire on front and sides to get it closer to the real organ shape you're trying for?
The second gold heart in the above post -- the gold one, has elements I could really see with your first inspiration picture -- the more delicate drawing.
I think I'd throw out the big, plump, vividly colored second inspiration piece. That doesn't say necklace to me. The first drawing you posted, I think has some real possibilities. As I said above, incorporating the wire elements of the heart with all the wires might also have possibilities.
Maybe give the jeweler more freedom to interpret the first drawing -- throwing out detail for a more pleasing whole.
