Irene Neuwirth - Irene Neuwirth offers a refined interpretation of the single earring trend with this 18kt rose-gold piece. It's crafted in the USA with a white diamond pavé-embellished bar and hook fastening that totals 0.13ct, then set with a pear-cut drop of yellow tourmaline – a stone sourced in the mountains of Sri Lanka. Style it as the sole accessory to silk blouse for a dinner party, keeping hair swept up to ensure it catches the candlelight.
