Mrs Creighton said she last recalled having the ring in 2006.
''I was out in the garden and, as girls do, very proud of wearing their rings and what have you, and I lost it.''
She searched for it at the time, but to no avail.
As the years went by, she gave up any hope of ever seeing it again.
Mrs Creighton was so excited and overwhelmed that she pulled the green top off the carrot in surprise.
She had been out in her garden every year digging up vegetables, laying compost and planting seedlings and never found the ring, she said.
''I just could not believe it. I was absolutely stunned.''
Earlier this month, Canadian woman Mary Grams also found her engagement ring wrapped in a carrot, having lost it at her family farm in 2004.
