Newark Torc Newark Torc The Newark Torc is a complete Iron Age gold alloy torc found by a metal detectorist on the outskirts of Newark-on-Trent, Nottinghamshire, England, in February 2005. The torc is made from electrum, an alloy of gold, silver and copper, weighs 700 grammes (1.5 lbs) and is 20 cm in diameter. The body is formed from rolled gold alloy wires, which had then been plaited into eight thin ropes then twisted together. The terminals are ring-shaped and bear floral and point-work designs. The torc was probably made in Norfolk. It closely resembles the Great Torc from Snettisham, now displayed
