Sea Glass Bead Necklace - Big Uranium UV Pendant

Very large bright green coloured mudlarked field found bead on an 18" sterling silver chain. The bead is faceted Uranium glass and glows under UV light! It was found on a field that had an old bottle dump from the 1920s in England. I have removed a small rust stain on one side - there is a shadow of it still slightly visible.
