Pieces: 1
Shape: Monoclinic crystal
Type: Violet Blue Scapolite crystal grown around by a Greyish Orthoclase crystal (Feldspar Family) A well formed monoclinic crystal system is one of the seven lattice point groups. A crystal system is described by three vectors. In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a rectangular prism with a parallelogram as its base. Hence two vectors are perpendicular (meet at right angles), while the third vector meets the other two at an angle other than 90
