The Cracked Crystal beads have a diameter of 6mm, the whole strand of chrased Rock Crystal is about 40cm long.
Cracked Rock Crystal is not, as the name suggests, frosted - the fine structure of the lines is created by brief heating. The fine crack structure can eventually recede through intensive wearing and the resulting skin contact, as the cracks are filled by skin fat and oil and become less visible. Careful cleaning with alcohol, however, brings out the structure again.
Cracked, crushed or icecrushed Rock Crystal or Crystal as well as Iris Crackled Quartz and Crackle Quartz is another name for Crushed Crystal.
