Edge length of Cracked Crystal cube beads about 4mm, length of the strand about 40cm.
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 Crackle Quartz are other names for Crushed Crystal.
