These are very, very petite!  half inch to a little over an inch.   My good source dried up, and these are all I can find.  They are not the best quality.  Believe me, I've been searching for better to no avail.  These have not been sorted through, about 10% of the weight is crumbs and other shells.

They are very small, but pair them with those tiny 6mm or 8mm triangles I just got in, and I think they would be beautiful and dainty.
