Description: A rather unusual, flattish quartz crystal with light amethyst / smoky colouring. It has two large, flat (?)negative crystals, each about 20 mm long (positioned roughly at a right angle to each other), that looks like two fully encapsulated crystals, with one of them having a minute crystal partially embedded in its side.
The crystal also has numerous small negative crystal inclusions and a small moving bubble, as well as fascinating growth patterns. There are also several minute, reddish hematite specks.
termination has a few very small nicks, while the lower part of the
crystal has a flaw and a large contact mark, where it parted from its
matrix at a sharp angle.
Chemical Composition: SiO2
Hardness on Mohs Scale: 7
Specimen Code: NBB 135
