Some pieces begin with a sketch. This one began with a friendship. The Josephine is named after one of Kinn's closest and most cherished friends of the brand—a woman who has been part of the story since the very beginning and whose vision helped shape this setting into what it is today. She wears it. Founder Jennie wears it. And now it is yours.

A ribbed gold solitaire setting with a bezel-set center stone, the Josephine is available in elongated cushion, round, and east-west oval—three distinct shapes, one unmistakable silhouette. The ribbed band adds texture and depth without competing with the stone, creating a ring that feels both architectural and deeply personal.

An engagement ring is not just a piece of jewelry. It is the first heirloom, the one that starts the collection, the piece that gets passed down with the story of how it came to be. The Josephine was designed to carry that weight beautifully, for a lifetime and beyond.

Designed and created in Los Angeles with ethically and sustainably sourced diamonds.

Your Vow ring is made to be worn every day and cherished for a lifetime. To preserve its beauty, avoid contact with harsh chemicals, lotions, and perfumes, and remove before any strenuous activity. When not worn, keep your ring safe in its Kinn packaging.

Clean gently with warm water, a drop of mild dish soap, and a soft-bristled toothbrush. Let it air dry in a safe place, and polish with a soft cloth to restore its shine. For diamonds, we recommend an annual professional cleaning to maintain their brilliance and ensure the setting remains secure.
