These are priced by weight and not necessarily by size.  There are variations of colors and I believe that is dependent on what mine they come from.  Unfortunately, the supplier does not provide that information when I buy them.  They put a variety in a package and sell them like that.  They are a reputable supplier from the UK and these are a very nice quality.  Turquoise is becoming more difficult to obtain.  There are many people out there selling fake Turquoise, but these are the real deal.  
 
I do always take one size to shows.  It varies which size I take.  Usually a size between $10-$17.  If there is a specific size you want, I would recommend ordering online.  Also, if there is a specific shade of color you like, you are always welcome to add a message with your order and I will do my best to accommodate your request.
