One of the most striking objects recovered from the bronze age site were the pair of exceptionally rare gold bracelets, 3000 years old,  made up of eight identical strands of twisted, square-sectioned, gold wire. Susan LaNiece from The Briish Museum established that the twisted wires are a little under 1 mm thick and have been joined side-by-side to form a flat band with their ends secured by flat, rectangular gold terminals. Both bracelets were found tightly coiled and were examined using optical microscopy and Scanning Electron Microscopy after minimal cleaning. Energy dispersive X-ray analysis in the scanning electron microscope on the surface indicated that the solder areas between the wires and where they join the terminals are slightly richer in copper and silver (at 77% gold, 20% silver and 3% copper) than the wires themselves and the terminal.
