A bordeaux shimmer stone stud in gold-plated brass carries a drop of faceted ebony onyx beads on a fine chain — the warm bordeaux-red of the stone sitting above the near-black of the onyx as the chain descends. The bordeaux shimmer stone departs from the ebony-dominant palette of the other shimmer stone pieces: it introduces a deep, saturated red-wine tone as the anchor, with the ebony bead chain providing the cool dark continuation. The chain drop adds length and movement below the stone, a deliberate change of material and register at the transition point. A drop earring for the bordeaux in the shimmer stone family.
