One Brazilian dealer at the show had about 5 flats of diamonds in conglomerate from Brazil.  I searched through all the pieces, and this was the best in the lot, with a large (for the locality) crystal measuring 7 mm from point to point.  

I have never seen this sort of specimen from anywhere other than Brazil.  Alluvial diamonds are usually off matrix, and matrix diamonds are rare from any locality.

On a lighter note, it was pointed out that it looks like a chocolate chip cookie....
