This is a very pretty and delicate necklace.   I have made it using 14KGF Jeweler's wire and lovely Aquamarine beads.  The beads are two shapes - 4mm round and then 5 x 4 ovals.  These aquamarine beads have a very sweet light blue color and are attached by figure 8 wire.  I have made a simple fishhook and figure eight closure.
