Item Description

This beautifully polished 93-gram quartz point holds within it a very elongated inclusion of brookite. That internal brookite crystal measures over 4 cm length and is terminated within! Actually, I see now it is doubly terminated! The terminations then flare off attached, hair-thin acicular needles of rutile, extruding from the brookite and shooting off into the quartz.
