The London-based Italian designer Barbara Bertagnolli draws inspiration for her one-off pieces from the colours, unusual cuts and shapes of the gemstones she selects. Working directly without drawings, she has her own distinctive technique combining silver and applied 24 carat gold with influences from the Medieval period, the Vienna Seccession and contemporary abstract forms.
