Ruthenium Chattering Skull Ring by Roz Buehrlen. This chattering skull ring has been designed to have three ruthenium chattering skulls, with a double enamelled setting on the shank. 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.
