While perusing YouTube the other day, I came across a channel created by a British mother-daughter mudlarking duo who make jewellery from their finds. They also make their own pieces, like this memento more silver skull pendant. (Mudlarking is basically sifting through the debris in river mud, in the hopes of finding unique, valuable and/or historic objects.)
This necklace is a one off piece, with a hand painted skull in the Georgian style. It sells for USD$365.79.
