WebFor gemologists, the scientific definition of a crystal goes right to the atomic level. A crystal is a solid whose atoms are arranged in a "highly ordered" repeating pattern. These patterns are called crystal systems. If … WebThe 7 crystal systems are NOT defined by translational vectors. This is where so much confusion comes from. While it is true that the cubic crystal system generates conventional unit cells with 3 perpendicular, equi-length axes, that is a coincidence (or at least, a correct fact which is derived from the true definition of a cubic crystal system).
WebSpecific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water. A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an equal volume of water. For instance, quartz with a density of 2.65 is 2.65 times as heavy as the same volume of water. WebFibrous. Fibrous is a habit name used when minerals occur in very fine fiber-like crystals.
