The company, which is run by Roberto Nicastro, was founded in 1976, and it initially included the U.S. market among its export targets. After the mid-'80s, however, when high-end construction in the U.S. slowed, the company turned to markets in Europe and the Far East, where it supplied stone for many prominent structures. Completed works include the Nikko Hotel in Malaysia, the Portman Ritz-Carlton in Shanghai, China, and several hotels in Hong Kong as well as the World Trade Center in Stockholm, Sweden, and the Langham Hilton Hotel in London, England. The company's Sodalite has also been used for renowned structures such as Buckingham Palace in London and the palaces of sultans in the Middle East.
As the market changed in the late '90s, International Italmarmi's focus turned back to the American market. Today, the U.S. comprises 40% of the company's exports, with another 35 to 40% going to the U.K. The remaining exports go primarily to Northern Europe. To keep in touch with its American client base, an International Italmarmi representative goes to the U.S. every month to visit customers.
