Since 1912, Oscar Heyman has been creating magnificent jewelry with the finest gemstones sourced from around the world at their atelier in New York City. Every piece of jewelry is signed and numbered, assuring the artistry and quality Oscar Heyman has delivered for over 100 years. The Museum of Fine Arts, Boston (MFA) published a book they wrote and researched on Oscar Heyman’s contribution to 20th century American jewelry and purchased a fifty-carat carved emerald brooch at TEFAF Maastrich in 2007 for the museum’s permanent collection
