Liver stones

I posted a questuon in the liver cleanse forum (it was removed by moderator..I don't know why) Here it is..what do liver stones look like? I didn't know there were such a thing, but on my seven day "NutriCleanse" (my first) I had these almost bile colored pea to marble size, firm, but breakable things that were a white-ish to clay color inside. I knew I had not eaten anything that would look this way. Sorry if my question upset the moderator but I would like to know?
Thanks for any help in advance
