This is probably the cause of the scarcity of free-growing hematite crystals, whereas the sagenitic rutile has been found quite frequently.
Streun and Kaspar Fahner opened a cleft containing fine crystals of quartz, epidote, calcite, sagenitic rutile, and slightly corroded, translucent raspberry-red octahedral fluorite crystals to 3.2 cm; the strahlers collected a total of 5 kilograms of fluorite from the cleft (Parker, 1973).
Some crystals are sceptered or reverse-sceptered, some are of the 'Tessin" habit and taper smoothly to points, and some are smoky or yellow ("citrine"), but the niftiest thing about this quartz is its variety of associations: around the bases of crystal groups and/or included within the crystals are creamy white, lustrous dolomite rhombs, green muscovite, and nests of gleaming red-brown sagenitic rutile needles.
