A gold brooch that is one of only three known examples in the world and the best preserved of them has been unearthed at Troy. The delicate piece features a long, tapered pin with four spiral rings at the top.The pin was found in the layer that dates to 2,500 B.C. Another extremely rare find was made in the same context: a flat jade stone that may have originally been part of a ring or jewel. A luxury import traded from distant lands, jade is very uncommon on the archaeological record of Early Bronze Age Anatolia. A bronze pin was also found in this layer.The brooch was unearthed in the layers of Troy II, one of the early settlement phases of the site.Scholars have long debated the beginning of this period, with estimates ranging between 2,300 and 2,200 B.C. The discovery has now provided clear evidence, dating the layer firmly to around 2,500 B.C.This breakthrough helps refine the chronology of Troys early history, which has been central to archaeological research for decades. The gold pin, jade stone, bronze pin and other objects found in this seasons excavation will go on display at the Troy Museum in anakkale
