I thought that this smoky quartz crystal was a tremendous bargain at the 1998 Tucson shows. It is in excellent condition, showing almost no damage, and has excellent form. It is odd in that 3 of its 6 faces (all which are "opposing", or not arranged adjacent to each other) are smooth and normally striated, wheras the other 3 are finely but intensely patterned (see the close-up image). It is also incredibly clear!
This smaller shark tooth is not nearly as impressive as the larger, aformentioned one on this page, but is actually much more unusual. It is of similar background to the larger tooth, but its fossilization was much different. Whereas most such megalodon teeth are black, dark gray, or dark brown in color, this one has a creamy, off-white coloration. Likewise, its density is much less than normal, so that a "dark" tooth of similar size would be quite a bit heavier. I believe that these traits are due to fossilization with phosphate minerals, instead of carbonate minerals, though I am not certain.
