The tons of sludge that were removed were spread out in the family orchard to level the ground. Using a rake to remove the stones and bricks revealed something much more valuable – a pair of gold torc bracelets.

They have ridged and crested bands and terminals formed as double spirals and are of the type created by Celtic goldsmiths at the end of the bronze age when they were regarded as high status objects, symbols of wealth and rank.

The pair will be offered in Monaco as part of the Hotel des Ventes de Monte Carlo’s July 21 sale of Antiquities with an estimate of €80,000-100,000.
