The pieces are priced and sold per stone, not by weight.  Size will vary and the coin in the photo illustrates the general size to expect.  Some of the pieces have a bail already attached, some do not.  The price is not based on the presence of a bail.  If you receive a piece and don't want to hand it from a chain or ribbon then you can easily remove the bail and incorporate it into your next metal clay project!  While we managed to acquire a nice inventory of these hand selected dichroic cabs, when they are gone - they are gone!   What you receive will be among the highest quality generally available!
