Abstract: Gall bladder stones are crystalline structures formed by concretion or accretion of normal or abnormal bile constitutents. These stones are normally made of cholesterol, calcium, phosphate, carbonate and proteins. The aetiology of gall bladder stones is multifactoral. Scanning electron microsscopy (SEM) is used here to investigate the surface features of the mechanically fractured part of the stone samples. Micrographs exhibit a non uniform polycrystalline surface without specific grain boundaries with porosity, leading to loose bounding of crystals and hence low specific gravity. These results pertaining to surface characterisation are very useful for understanding the disintegration process of stones inside or outside the human body.
