Joel Arthur Rosenthal, known as JAR, is celebrated for his intricate and extraordinary jewellery. The Paris-based designer makes work for an elite clientele; drawing from the natural beauty of precious stones, and combining their often vibrant colour with sculptural design. His finely tuned expert eye and exacting personal taste are second to none.

For this exhibition, JAR turns his eye to The Portland Miniatures. He has chosen an intriguing selection of jewel-sized paintings. In addition, these miniatures are accompanied by some of his favourite pieces of jewellery from The Portland Collection.

A highlight of the exhibition is a pair of rings that we believe were last together in 1786 – this exhibition will bring them together for the first time in over 230 years.
