i think they are afraid a rhinestone might fall off and drop onto the steel band clamped on to hold their 20 pound shoes on and then it will be like the straw that broke the camels back, just that 1/1000 oz extra weight will make the horse's whole foot fall off. gotta be it. and you gotta wonder about a world where they have padded shoeing/pressure shoeing/acid on the coronet band/mustard oil on the fetlocks but a rhinestone, oh the humanity.
