Scope note
A handsome shell marble from Tortosa, Spain, where it is still quarried. Its predominant color ranges from a reddish lilac to yellow, the color being dependent on the quantity of embedded snails: the yellow represents the mollusk and the lilac represents the seabed in which it sank. Broccatello was used extensively as surface ornamentation in churches in Rome and Naples, Italy.
