This is a statement piece. The brooch includes an O-ring to wear as a pendant as well as a brooch. Sterling silver trim and chocker necklaces. The ox looks to be carved out of ivory, but I am unsure material. The stone on the ivory is likely Baltic Amber based on my readings of the artist. The large stone on top, I am u certain to its origin. Necklace has hook eye closure. Pendant measures approx 3”
