Giovanni Barbieri’s new limestone tile series is peppered with small divots and smooth, hand-hammered undulations for a stone flooring that looks old yet delivers a polished surface suitable for use as a contemporary interior backdrop. Designed in collaboration with New Ravenna Mosaics, the Timeworn series comes in gray or beige hues. New Ravenna Mosaics. 757.442.3379. www.newravenna.com.
