These are priced by weight and not necessarily by size.  Also, I doubt I will ever be able to obtain any more of these.  I ran across them one year in Tucson and I don't have the name of the place I got them from.  I was on a "tumbled stone" quest that year.  I'd just walk into random tents and ask if they had any tumbled stones.  These were the only tumbled ones they had.  They have done really well on the online store.
