Ruthenium Chattering Skull Studs by Roz Buehrlen. These mini hand carved skull earring pip studs have been created with ruthenium, making them the perfect everyday accessory with your outfits. About The Designer: Roz Buehrlen’s design style is based on nature, but she can draw inspiration from anywhere. Roz travelled extensively during her childhood and visited cultural hotspots such as Kuwait and India. When she returned to the UK, she studied at the Camberwell College of Arts, and then worked at a bronze foundry in Suffolk. These expansive educational experiences led to her discovering she had a passion and talent for sculpting, crafting, and smith work. Fascinated by the casting process, Roz, built her own foundry studio, and eventually, her eponymous jewellery brand. To view more of this designer\'s collection please visit Roz Buehrlen.
