Clear Quartz: crystal - DT Tabby

Another crystal that was once part of our teaching collection, this is a nice natural Tabby crystal that is in DT formation - possibly due to self-healing, as the faces are unusually textured. Although the terminations are not wonderful, there is some nice stepping to the sides, along with a few bridge crystals and keys. One face also has a prominent record keeper, and some unusual layered steps to another, perhaps indicating where the pattern of growth had shifted.
