Our Story

William & Henri – Fine Jewelry brings precise workmanship, vast expertise, and a deep-rooted history to every diamond that bears its name. Each aspect of the manufacturing process is completed by hand, from stone sourcing to individual facet polishing. A William & Henri diamond receives meticulous attention to detail and the utmost care. As fourth generation diamantaires, the owners of William & Henri understand what it means to create a work of art that endures a lifetime.

Love motivates and imbues every feature of William & Henri’s work. Founded to help friends bring to life the perfect engagement ring or special gift, William & Henri’s intimate philosophy creates an unparalleled creative experience. From a showroom located in the heart of New York City’s Fifth Avenue, a William & Henri consultant will help identify the ideal stone and work closely with each visitor to create an exceptional jewelry design. From this inspiration the team fabricates a customized setting to house the diamonds, crafting a statement as distinctive as the passion each couple shares.

W & H shares its knowledge of diamonds and fine jewelry in personal consultations, where guests will receive an education tailored to their needs. Here visitors can discover the William & Henri Fine Jewelry collection, or uncover the unique extravagance of the Diamond Rental Program. No matter the size of the stone, bought or borrowed, William & Henri redefine essential luxury one carat at a time.

All William & Henri diamonds are 100% natural and conflict-free. We are involved in all aspects of the manufacturing process, ensuring our diamonds originate from ethical and conflict-free sources. Additionally, we use the internationally recognized Kimberly Process to certify that our diamonds are obtained using legitimate means and are not used to help fund conflict.
