Other grains added to the twin form crystals that often appear symmetrically joined, sometimes in a starlike or crosslike shape. WebSpar is an old mining or mineralogy term used to refer to crystals that have readily discernible faces. A spar will easily break or cleave into rhomboidal, cubical, or laminated fragments with smooth shiny surfaces.
