Making Dreams Come True
Since 1902

From engagement rings that will take her breath away to stunning jewelry that will let someone know how much you care, Diamond Castle Jewelers has what you need to make those precious moments unforgettable.

Novi’s Home for Fine Jewelry Since 1902

For over 120 years, Diamond Castle Jewelers has been Novi’s family-owned destination for fine jewelry, expert design, and on-site repair. As jewelers since 1902, we’ve built our name on something simple: a welcoming smile at the door and exceptional service every step of the way. We specialize in loose diamonds — most of them GIA certified — and our gemologists and expert staff will help you find the perfect stone in any size, shape, and quality, with craftsmanship and value you can trust. From resizing a treasured ring to designing a custom piece all your own, we’d be honored to help you find something as lasting as our legacy.
