In the 1960s and 1970s Helga Zahn (1936-1985) was one of the leading jewellery artists in Great Britain. She had a preference for silver and natural materials such as pebbles. Her vocabulary is formed from the clarity of simple geometric shapes - the rectangle and circle - from the simpilcity and sobriety of connecting elements - mostly simple small rings - and from an almost starkly reduced colour canon: silver, black, brown. Exceptional one-off jewellery pieces emerged, partly using found objects.
