onion-stone

Updated: May 4, 2025

Intermediate between the white marbles used for external architecture and the coloured marbles used for internal decoration, and forming the link between them, is the variety called by the Italians cipollino, or onion-stone. Its classical name is Marmor Carystium, from Carystos, a town of Euboea, mentioned by Homer, situated on the south coast of the island at the foot of Mount Oche.
