Screw Quartz Crystal Cluster – Inner Mongolia, China
This is a rare screw quartz cluster from Inner Mongolia, China, displaying a radiating group of quartz crystals with an unusual surface texture. Each crystal exhibits distinctive horizontal striations and subtle spiral-like growth patterns, earning the nickname ‘screw quartz.’ These formations are the result of complex elestial or skeletal growth under fluctuating conditions, producing interrupted or stepped crystal faces.
