Cholesterol Gallstones : Appearance

Comments:
Cholesterol Gallstones: They can be small or large, single or multiple, round to ovoid, and pale yellow in color. Pure cholesterol stones (100% cholesterol monohydrate) have golden yellow color, whereas mixed cholesterol stones are darker, greyish-yellow to brown due to increasing amounts of calcium carbonate, phosphates, and bilirubin.

Cholesterol stones have a finely granular, hard external surface and a radiating crystalline or laminated interior. Facets develop when multiple stones form and grow within a confined space. The consistency is hard and they are not easily crushed between thumb and index finger, unlike the pigment stones.
