What Crystal System Is Diamond? The Special Jewels
In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point). A lattice system is a set of Bravais lattices. Space groups are classified into crystal systems according to their point groups, and into lattice systems according to their Bravais lattices. Crystal … See more Crystals can be classified in three ways: lattice systems, crystal systems and crystal families. The various classifications are often confused: in particular the trigonal crystal system is often confused with the rhombohedral lattice system See more The 7 crystal systems consist of 32 crystal classes (corresponding to the 32 crystallographic point groups) as shown in the following table below: The point symmetry … See more Two-dimensional space Two dimensional space has the same number of crystal systems, crystal families, and lattice systems.

WebDiamond belongs to the cubic crystal system, which is the most symmetrical of crystal systems. The basic crystal shape, or habit, of diamond is the octahedron; a form with eight equal triangular sides, … WebDiamond belongs to the cubic crystal system and should therefore exhibit isotropic optical properties. But it is well documented that diamonds often show weak birefringence. This study has focused on the causes of strain-induced birefringence in natural diamonds: dislocations, lattice parameter variations, inclusions, fractures, and plastic ... WebMay 16, 2024 · Diamond falls in the category of “Cubic crystal system” also known as “The Bravais lattice”.
