Sac Bijou Birkin by Pierre Hardy, 2012

These miniature rose gold and diamond accessories from the Haute Bijouterie Collection are small enough to be worn as a bracelet but are functional. Designed by Pierre Hardy, creative director of fine jewelry at Hermès, each piece features 2,712 diamonds. In 2019, another version of the Sac Bijou Birkin was released, comprising black garnets and spinels instead of diamonds.
