The replicas of the Carne Cross have been carved by Gloucester Cathedral stonemason Wieslaw Szod, using sandstone from the Forest of Dean.
Three replicas of a cross carved by a prisoner in the Korean War have been blessed by the Bishop of Gloucester.
The original - known as the Carne Cross - was made by Lt Col James Power Carne of the Gloucestershire Regiment and is housed in Gloucester Cathedral.
One replica will go on display in the cathedral, one at the Soldiers of Gloucestershire Museum, and one will be sent to Paju in South Korea.
They were blessed at Gloucester Cathedral on Sunday,
The ceremony was held 70 years on from the Battle of Imjin River, where Col Carne led about 700 men of the Gloucestershire Regiment against more than 10,000 Chinese, between 22 and 25 April 1951, on what has now become known as Gloster Hill.
It allowed UN forces time to retreat to defensive positions north of Seoul and led to the regiment gaining the nickname The Glorious Glosters.
Col Carne was eventually captured and while he was held, he carved a five-inch-tall (13cm) Celtic cross out of volcanic rock using, it is believed, just a nail.
Trustee of the Soldiers of Gloucestershire Museum, Lt Col Tony Ayres, said the original cross was moved from an alcove in the cathedral to its treasury about four years ago when "it became clear it was now a high value artefact".
Cathedral stonemason Wieslaw Szod said it was "an honour" to have carved the replicas.
"[Col Carne] made a great job, according to the conditions he was in, in a prison, using very basic tools," he said.
