Rottermond Jewelers, Milford

If it's meant to be treasured for a lifetime, it should come from Rottermond Jewelers. At least, that's what many Michigan grooms figure when they get down on one knee—so many that Rottermond keeps a running list of engagements that use their stones. It's these kinds of small, careful touches that snagged Rottermond a spot on wedding site The Knot's list of best wedding-ring vendors in the Detroit metro area in 2014.

In the store itself, Rottermond's passionate gemologists pair their old-fashioned attention to detail with a host of modern technologies. Customers can choose pre-cut baubles from labels like Rhythm of Love, Hearts on Fire, Scott Kay, Simon Golub, Valina, Martin Flye,r and Bridal Bell, of course, but they can also opt to design their own rings using 3D software. Even the repair services include lasers and other high-tech tools. Appraisals and gold quotes are among the remaining Rottermond services, but many visit the Milford and Brighton locations just to peruse the glittering wares.
