This is an unpolished Fire Quartz crystal that has been in my personal collection since 2004. When I bought it, I was told it was a Natural Titanium Quartz, but I feel that it has much of its colour from Lepidocrocite and iron, and looks not dissimilar to a Harlequin Quartz. It has a slightly rugged surface with superficial phantom deposits of black, orange and red, and a nice clear core. Although it has a rather flat termination, it is a good trans-channeller formation.
