Oscar Heyman’s unique combination of engineering capabilities, technical skill and artistic style enables us to create one-of-a-kind custom pieces. For instance, a diamond necklace comes with interchangeable ruby and sapphire drops, which can also be attached to studs and worn as earrings; one versatile design yields two necklaces and two pairs of earrings. We accept commissions for original designs.
