This necklace is part of a series based on a series of drawings of seed heads, the enamel Shard section features some direct drawing into the enamel which is then fired.
Cleaning Instructions
Enamel is basically a type of glass, therefore it must be treated with a certain amount of care.
I recommend that the silver areas are cleaned with a Silver Cloth ( such as Goddards )
I would avoid using a liquid silver cleaner as this may affect the enamel.
