In days when marble blocks were still carried on ox-drown carts (the 1920s), the Testi family owned two quarries in Sant’Ambrogio di Valpolicella: one of Rosso Verona and the other of Bronzetto Verona. The famous marbles were quarried by the Testi family and sold to local and foreign Companies.
After the War and after post-war reconstruction, (in the early 1970s), one of the sons, Claudio Testi, founded the Testi Fratelli  partnership.
He was joined by his brothers Gustavo and Riccardo – at the time employed elswhere (one in Switzerland, and the other at a major local marble firm) – each contributing new experience and professional skills to those already acquired at the family quarry by then no more in production.

Today Testi Fratelli leads a Group of independent, associated companies offering domestic and foreign markets, a wide range of products and services. With the arrival of Graniti Marmi Affi (founded in 1970s)the Group was in the position to offer anything from paving slabs, curtain walls and cornices to ornamental fountains and monuments. With Combus , Segraf, Savoia & Lugoboni and Testi do Brasil (joined later) the services are extended to: marble polishing and resin treatment,granite gangsawing, diamon cut flooring and modulgranite.

Though one of the major Groups, it has remained loyal to its roots, still giving great importance to its Serbias quarries in Sardinia (Italy) (Bianco Sardo Luna Pearl, Bianco Sardo Champagne, and Serbias – Grigio Malaga) and in Piedmont,Italy (London White^TM and Duke White^TM granites).
It also imports rough blocks of marble and granite from northern Europe, Spain, Brazil, India, South Africa and elswhere. 86% of the Company’s turnover is from the exportation of finished products, keeping in high consideration the national market as well.
