Annette Petch works in silver and gold to produce hand made jewellery and small objects such as bowls and boxes. Recently she has begun using a new kind of sterling silver called Argentium, which is made from recycled silver and does not tarnish. Most of the gold she uses is also recycled. Annette is based in Sheffield, UK.

Her designs are based on natural forms including leaves, flowers, buds, seed pods, and shells, and the secret spaces found within them. Annette likes to incorporate texture, and the sounds of pebbles on the beach, wind rustling through the leaves, or water running over stones.

Ethical Silver

Argentium silver is a high purity jewellery alloy that meets the hallmarking requirements for the UK standard. The alloy modifies the conventional sterling silver composition with the addition of germanium.
