International Tumble Stone was founded in 1999 by John Marjamaa. His work with stone started in 1994 when he was building a new house and wanted granite counter tops in it. Soon he was buying saws, polishers and other tools and starting a new business with a partner (gargoyle granite and marble). Marjamaa, who gets bored very easily soon sold his share and decided to take on bigger rocks! It takes a big saw with a diamond wire to cut rocks up to 8 feet wide. John decided to build his first one, rather than pay to import one from Japan or Italy. Soon after came the drills, polishing equipment, cranes, forklifts and all of the other specialized equipment it takes to fabricate rock into one of a kind pieces of art. Over the years John brought on a well-equipped staff consisting of his son and other close friends and family members. Today Tumble Stone employs about 20 people and ships rock all over the US and Canada.
