Name and quarry location: | Sicilian jasper, probably diaspro di Collesano, probably from Collesano, Palermo, Sicily, Italy |
Geological description: | Yellow-brown jasper with cavities and fractures infilled with chalcedony which is agate-banded in places, or with colourless crystalline quartz. Some dendrites of manganese/iron oxides are evident. |
Comments: | 'Solisano' is almost certainly a mis-spelling of Collesano, a source of jasper and agate according to Montana (1998) who cites Borch's spelling 'Golizano'. Tata (1772) lists jaspers from 'Monte di Golisano'. Jervis (1881, 1889) also describes jaspers and agates from this locality. |
