Irene Neuwirth’s pink ring is encrusted with a smooth marbled watermelon tourmaline, which showcases the founder's talent for sourcing precious stones in vibrant hues. Handcrafted in Los Angeles, it’s cast from complementing matte 18kt rose gold and framed with small white pavé-set diamonds, totalling 0.15cts, for a touch of sparkle. Wear it with ice cream-hued separates for a warm-weather occasion.
