Sisters Christie and Rosanna Wollenberg blended their backgrounds in art and luxury fashion into their jewellery boutique, Otiumberg. Everyday elegance leads the London label founded in 2016, setting precious stones in designs for the modern woman's lifestyle with delicate earrings, necklaces and beyond. SUSTAINABLE STEPS — Otiumberg uses recycled gold, ethically sourced stones, recyclable organic and FSC-certified packaging, and has completely eliminated plastic from their supply chain.
