Thanks again everyone! I called my stones tan but they could definately be considered goldish. They were definately a darker brown color on the inside though. Maybe a little green. I wish I had examined them more closely but to be honest, since they were so different than previous stones I thought they were possibly bowel material and didn't want to mess with 'em too much! Anyway, I am convinced now that they were infact stones and I am glad those suckers are gone!! They were so big- about the diameter of a quarter and most were alomost perfectly round. I passed around 10- 15 two different times. I did save a couple and they sort of just started to melt away, just like the green ones I've had do when left at room temp.
