I have seen common opal boulders up to 7 feet across. Common opal is at times formed in huge pieces. In Washington state I have seen vertical walls of diatomaceous earth pits with solid opal over 30 feet tall and a thousand feet wide.

That diatom opal is mighty pretty, too. Yellow and milky. Met a gentleman in Hope, ID with multiple  hunks lining his driveway, all over two ft square. Guess you gotta work at the mine to get those crumbs!
