Using some (of my MOST favorite) black steel and some 8mm vintage (glass) pearls, I created single swirled components out of the 19gauge steel using a hand-concocted jig (simply a 3/8" metal rod in a piece of pre-drilled teflon) and my needle nosed pliers. That satisfied my desire for symmetry in each unit and made it much easier to form each swirl.
Before I added the loop at the end, I slipped on an 8mm vintage pearl and then connected them so the necklace resembles a sort of vine curling around itself and up and around the neck, and the pearls seem to float on the vine.
I added a hand formed "S" clasp and an extender chain (for added length), but once it was on it seemed too plain, so I added three lengths of curved, hammered steel, staggered in length, each with a pearl, to the center unit. When on, the necklace sits on the collarbone and the center dangle rests just at breast level.
