Museum of Jewelry & Adornment
Wander an immersive museum of jewelry and adornment — the gemstones and precious metals that catch the light alongside the rings, necklaces, and heirlooms passed down through generations, and the craft of the jeweler as told through art and history, each in its own gallery, so you can get to know the stories behind the pieces we treasure: where each stone and style came from, what makes it matter, and the role it plays in how we adorn ourselves today.
