Brookite with AnataseEven though Brookite and Anatase are polymorphs, they are rarely found in nature together. As a matter of fact, compared to Rutile and Anatase, Brookite is considerably rarer. This piece is the only specimen to feature Brookite and Anatase together. Out of the hundreds of pieces I've seen from this area, it's incredibly difficult to find any specimens with both species together. A sharp, gemmy, lustrous, flame red colored 9 mm crystal of Brookite is

layered blades of Ferberite on the side

A very attractive “locality” specimen from Corocoro which was collected in October of 2010

"sword"-shaped crystals of Vivianite with metamorphosed Sandstone

well-formed dodecahedral crystals which are associated with a few gemmy prismatic Quartz crystals

fairly sharp
