This object is so fascinating:
Bush Barrow dagger - Wessex Museums
The Bush Barrow dagger is one of the most incredible Bronze Age finds in Britain. The blade is made from bronze, but the handle is decorated with microscopic gold studs set in a zig-zag pattern.

Each gold stud on the dagger handle is as thin as a human hair and most are less than one millimetre in length.
We counted how many studs there were in a single square centimetre. Then by multiplying that up for the surface area of the dagger handle, we estimated that there were around 140,000 gold studs.
