Description: A fascinating group of quartz crystals with three generations of quartz growth.
Milky to clear quartz crystals received a thin coating of iron oxide and minute hematite crystals. This received a very thin coating of quartz growth, and finally another growth of quartz, resulting in the spectacular clear termination.
The clear crystal termination has a minute nick, while one of the larger crystals have a long chip running nearly its full length (visible on 1st image, right hand side). The matrix is a few broken pieces of crystal.
