bandsaw/diamond wire

has anyone ouy there modified a woodworking band (http://maplered.com) saw to cut Marble (http://www.lightemprador.com) /Granite (http://tanbrown.org) for mosaic or inlay with any success?? i'd like to find a source for a diamond wire , or small flat blade, length about 94-95" long to try to convert my saw to wet-cutting. the little band (http://maplered.com) saws i've seen are too weak. any help or advice is greatly appreciated as i have a commissioned piece on the horizion... thanks
