The “Yes” happened on the water. The ring began on paper.

Months before that, the two of them sat down with Liza and described something that did not exist yet. Two stones, yellow gold, an emerald set into the band. Designed with them, then made for them.

We wrote the guide because the caption comes up every week.

What to give the one you’re marrying, for the bride and for the groom. A bracelet, the alternatives when a bracelet is not the piece, and a watch that outlasts the day by decades.

Between the vows and the first dance, a quieter tradition.

The gift exchanged on the morning of the wedding. Not the rings, which speak for themselves, but a piece chosen for the person, one they will wear long after the day is over.

“I thought it would take two weeks.” It won’t.

A custom ring takes six to eight weeks from the day the design is finalized. First conversation to ring in hand, closer to ten to twelve.
