Golden Bark Nugget - 9ct gold with white diamond*** This necklace has now sold. I can make another but it will vary slightly from the image shown below as each nugget is unique*** This 9ct gold nugget of English Oak bark features a single white diamond. Each nugget is completely unique, cast directly from an individual piece of bark. (You can read more about the creative process here.) The nugget hangs from an 18 inch trace chain. It works well on its own, or as an addition to any 'neckmess'.
