At first, I thought that this was a hexagonal dipyramid with one tip broken off. But a loupe reveals an interesting six-way pattern on that flat end, indicating that it is a growth pattern. Also, instead of being just one sapphire crystal, this actually has two more tiny crystals attached. And, there is a square hole which appears to be filled with quartz crystals. The quartz, and the crevices of the sapphire, have a somewhat dirty appearance from minerals that are not easily removed.
