Il Pezzo Mancante — Italian for "the missing piece" — is a Tuscan atelier for handcrafted lighting and furniture from noble materials, founded in 2010 in Florence by Cosimo Terzani and Barbara Bertocci. Cosimo Terzani — son of Sergio Terzani, who founded the renowned Florentine lighting studio Terzani | La Luce Pensata in 1972 — previously served for nine years as Creative Director of the family business. Barbara Bertocci brings her background in fashion, theatre and entrepreneurship as Art Director, concept designer, brand voice and bridge between atelier and client. In 2010 they founded the atelier, initially with outsourced production, then — after two years — entirely in their own workshop: for complete control over quality and the possibility of creating genuine one-of-a-kind pieces. The "Missing Piece" — a small brass cylinder with serial number — is embedded in every piece and seals authenticity and uniqueness. Atelier: Via Roca Tedalda 31, Florence.

Materials: solid wood (walnut, wenge, ash, oak — natural oil finish), brass casting (hand-forged, hand-welded — legs, handles, structural elements), mouth-blown crystal (diffusers and candle elements), marble from the finest Carrara quarries (Calacatta Gold and others).
