The gallbladder is located on the liver and near the stomach. Gallstones form when cholesterol or bile stored in the gallbladder hardens into pieces of stone-like material. Gallstones are made of cholesterol salts and bilirubin salts. Gallstones can be as small as a grain of sand or as large as a golf ball. The gallbladder can develop just one large stone, hundreds of tiny stones, or almost any combination.
