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.

WebTools. Facets ( / ˈfæsɪt /) are flat faces on geometric shapes. The organization of naturally occurring facets was key to early developments in crystallography, since they reflect the underlying symmetry of the crystal structure. Gemstones commonly have facets cut into them in order to improve their appearance by allowing them to reflect light. 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).
