A jewel of downtown Plymouth is about to close its doors.

After operating in the western Wayne County city since the mid-1970s, Delta Diamond will close its doors at the end of the month.

“We’re leaving at the right time for us,” said Aurelia Piotrowski, the wife of Thomas Piotrowski, who owned the shop until his death in 2016. “We’re holding our heads up high and we’re going to try different things.”

The shop originally opened in 1973 in Dearborn before moving to Plymouth a few years later, first operating in the Mayflower House before eventually landing in its current home at 895 W. Ann Arbor Trail, where it’s been for several decades, seeing plenty change downtown throughout the years. 

“Town has a different vibe, but it’s good,” said Kathy Aschermann, Piotrowski’s daughter and a gemologist at the shop. “Everything changes. You can’t have all retail and no service.
