Literally hundreds, if not thousands more accounts of analyzed stones can be found on other sites simply by spending some quality hours with Google or your favorite search engine.
The overwhelming ingredient in the green stones is cholesterol, with bile, bilirubin, calcium, and protein appearing on occasion. The variations depend on the history of the patient, the condition of the liver and gallbladder, calcification level of the stones, and other similar sorts of variables.
Interestingly, allopathic medicine likes to say that bile *is* fecal matter.
