I Love Harbor Springs
The Petoskey Stone You Won't Leave Behind
Our colorful enamel Petoskey stone necklaces turn Michigan’s most iconic shoreline treasure into something special for every day.
From Harbor with Love
Hi, I'm Kristy, cofounder of Plum Diamonds and Harbor Springs native. Even from across the lake, I still like to think Plum was grown "up north" with love; inspired by small-town warmth and thoughtful service.
The Subtly Nautical Jewelry You've Been Missing
Inspired by days on the water, our Lake Cleat Knot Pendants capture the familiar shape of a boat cleat wrapped with a tiny rope detail. Available in precious metals and made for lake lovers, boat people, and anyone who feels most at home near the water.
THE LAKE KNOT PENDANTMichigan Mahjong Tile Keepsakes
