WHAT IS BROOKITE?
BROOKITE CRYSTALS: LARGE, BEAUTIFUL, REDDISH- BROWN CRYSTALS OF BROOKITE FROM THE FAMOUS KHARAN, BALOCHISTAN, PAKISTAN LOCATION. SOME OF THE WORLD'S FINEST BROOKITE CRYSTALS COME FROM THIS AREA, BUT THEY ARE HARDER TO OBTAIN NOW DUE TO THE POLITICAL UNREST THERE. CRYSTALS UP TO 4 1/2 CM TALL! SOME SINGLES, DOUBLES, AND OTHERS ON MATRIX WITH QUARTZ CRYSTALS. BROOKITE IS TITANIUM DIOXIDE AND HAS THE SAME CHEMICAL COMPOSITION AS RUTILE AND ANATASE, BUT IS IN THE ORTHORHOMBIC CRYSTAL SYSTEM. IT IS RARE, HAS A HARDLNESS OF 5 1/2-6 AND RANGES IN COLOR FROM YELLOW, RED, BROWN, TO BLACK. THE FOLLOWING SPECIMENS ARE VERY REASONABLY PRICED. TAKE A LOOK!
ANATASE CRYSTALS ARE ALSO TITANIUM DIOXIDE IN COMPOSITION, BUT THE CRYSTAL FORMATION IS TETRAGONAL ALSO FROM THE SAME LOCATION AS THE BROOKITE.
