Bog oak is a fossilized wood that's been preserved in Irish peat bogs for hundreds or thousands of years. This unappealingly named but very attractive material was used self-referentially during the 19th century to produce Irish-themed jewelry, harps and clovers being the most common motifs. These unusual bog oak earrings are carved in the shape of bluebells, the stamens are suspended from concealed silver loops which allow for lovely movement when worn.
