WOW! THE PIC SAYS IT ALL! THIS CLEAR, doubly-terminated quartz encloses a 2.2 cm doubly-terminated brookite crystal that is floating in perfect alignment to the axis of the quartz, as if it grew around the brookite as a seed! Small acicular rutile crystals shoot off the brookite, as well. This small treasure, for rarity and novel aesthetics, is one of the best included quartzes of ANY type that I have ever seen. It has every quality you can ask for in a significant inclusion, including the fact that the brookite even on its own would be a major example of the species.
