Monica’s special interests are the mineral and polished decorative stone collections. She is author of Decorative Stone: the Complete Sourcebook (Thames and Hudson, 2007), and produced the Corsi Collection website which holds images and descriptions of all 1,000 specimens in this early 19th century collection of ancient and contemporary decorative stones, a project funded by the Esmée Fairbairn Foundation. Until her retirement in 2018, Monica was Head of Earth Collections and Collections Manager for the mineralogy and petrology collections at the Museum. She currently provides curatorial support, in particular working on the cataloguing of mineral collections.
