A killer thumbnail specimen of brookite, from the exciting recent finds in Pakistan that have happily supplemented the formerly very rare occurrences of good brookites around the world. This one is really special, with two interpenetrating crystals and even a gemmy, doubly-terminated quartz crystal on one side of the specimen. The smaller brookite has minute edge wear, but as the specimen is displayed, what you are looking at is the perfect larger crystal, so it really doesn't matter. Superb! 2.5 x 1.5 x 0.7 cm
