Birefringent urine crystals
WebCrystallographic Origins of Birefringence. The property called birefringence has to do with anisotropy in the binding forces between the atoms forming a crystal, so it can be visualized as the atoms having stronger "springs" holding them together in some crystalline directions. A useful situation with mineral crystals occurs when there are two distinct indices of … http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/biref.html
