"It was brought in to me and I could see it had been dropped obviously and I said to Helen's fiancé (Steve Backshall) who brought it in that it looked like it had been dropped on concrete and that's pretty much what had happened.
"He (Backshall) admitted to having dropped it himself.
"It was damaged on two edges - on one edge quite badly and the other less badly. But it was quite a mission to restore it.
"They are pretty heavy and bigger than you think. They are about 4in in diameter and must weigh half a kilo and they are solid silver in actual fact and gold-plated on the top so they are a very special piece of jewellery really.
"I feel very honoured to have been trusted with restoring such a priceless object.
"I am very pleased with the way it came out and I think Helen Glover is very pleased as well."
