To commemorate Kanshi Hashimoto's 2012 donation of 870 pieces of jewelry from the Hashimoto Collection, The National Museum of Western Art is showcasing around 300 of the 760 rings in the collection. These rings — many encrusted with diamonds and other gems — represent various periods of history, the oldest dating back 4,000 years. This is the first time they are being shown to the public.

To show them off as accessories and statement pieces, many of the selected pieces will displayed alongside mannequins styled in garments of the same era. From the courtly 18th-century Rococo fashion of Marie Antoinette to the early modern 20th-century styles of Coco Chanel, the outfits, on loan from the Kobe Fashion Museum, provide a full picture of how the rings were originally worn; July 8-Sept. 15.
