A conglomerate stone composed of rounded quartzite pebbles that are cemented together with a siliceous paste. Cut and polished stones resemble plum pudding. Puddingstones are normally used for decoration rather than building construction as they tend to be coarse and friable. One notable exception is the puddingstone quarried in Roxbury, Massachusetts, that was used considerably as a building stone in the Boston area.
