Clear Quartz: crystal - Chlorite Included Key Channeller

This is a good-sized unpolished Chlorite included Quartz that has been in our teaching collection for a number of years. The green-black inclusions are veiled and layered towards the base of the crystal, whilst the upper half remains very clear with only minor veiling. The termination is fairly clean; the main face has seven nicely symmetrical sides, and there is a good key indentation to one side.
