Can crystals be divided into smaller pieces?

Yes, crystals can be divided into smaller pieces through a process called cleavage, which occurs along specific planes of weakness in their structure. When a crystal is broken, it tends to split along these planes, resulting in smaller crystals with the same internal structure. However, the smaller pieces may not maintain the same external shape or size as the original crystal. Additionally, excessive fragmentation can lead to irregular shapes rather than well-defined smaller crystals.
