Why We're Obsessed:

In 1912, Oscar Heyman and his younger brother Harry founded Oscar Heyman & Brother. Initially when he came to New York he worked for Faberge and later became Cartier's first non French jeweller. Today in the Madison Avenue workshop, the mission is to create pieces that endure in form, function, and beauty; all handmade resulting in jewellery that is defined by intentional geometry with carefully chosen gemstones to suit each silhouette.
