Nic took his Great Grandma Kuetemeyer's ring and Busha Kowalski's ring into a small jeweler in Powell, Ohio and asked the jeweler to make a ring that joined two family histories into one future.
OK so, he probably didn't word it much like that, but that's essentially how it went down.
The main diamond is from Julie's Busha's ring, the diamond on the side of the main setting is from Great Gradma Kuetemeyer's.
