These are so called crystals. They consist of an internal kernel and a peripheral cover learn more on engagement rings http://www.offshelf.com/. The kernel, as a rule, is presented by the colorless octahedron similar on physical properties to crystals of a version I, and a cover an octahedron if it has an insignificant thickness. At increase in a thickness last changes the form itself and changes the kernel form, giving to all crystal cubic shape. At dissolution of sides the crystal turns to the roundish. Thus, forms of these difficult crystals can change from octahedron and their doubles to cubes and roundish dodecahedrons. Coloring of crystals of a difference IV is defined by color of covers and more often has a yellow and chartreuse shade. Characteristic property of this version is presence of single atoms of nitrogen with paramagnetic properties. The isotope structure of carbon in a kernel and in a cover is close on the indicators and corresponds to a source.
