This started out like the "Swallow Tail" pendant design, but part way through it was obvious it wasn't going to work the same because I was using larger beads. So I just made the two halves without connecting them. Then I strung on the stone bead, so it could dangle off a picot from a ring. The middle is connected together with some chains and shuttle joins -- the kind that lock the chain. The larger pearls were put on long picots before I joined to them.
This design needs additional experimenting. You'll probably see a lot of variations on this before I attempt to share a pattern from this idea in more detail.
