These ‘picture agates’ were highly prized as microcosms of the natural world, collected by artists and scientists alike. 
The artist Thomas Gainsborough had a picture agate ring in his collection which is now in the Ashmolean Museum, Oxford. The stone in this pendant is the same type material as the Gainsborough ring.
