Excavating a Bronze Age tomb on the Isle of Man, archaeologists found a spectacular jet necklace. These were widely traded luxury items at the time, found on several British and French sites; I posted another one here. The jet seems to come from Yorkshire although other sources are possible. This one is said to be 4,000 years old.
This one was made up of intricate plates that presumably formed a symmetrical design; I can't wait to see what it looks like reassembled.
