Window quartz crystal with interesting gas inclusions and good termination

Measurements:  83 x 52 x 20 mm

Description:  A milky to clear window quartz crystal with patches of faint amethyst colouring. The crystal has lots of interesting gas inclusions and flaws and one deep window. It  seems like the crystal's growth was subjected to very high temperatures. 

The cream to brownish colouring is due to clay that was caught up in the window. There are a few small nicks to the crystal and damage to the bottom of it. 

The termination is good.
