A gemmy, light blue topaz crystal from the prized locality of the Little Three Mine. Though it is evidently could not be removed in its entirety, most of the faces are intact, and are super-sharp. The interior is so clear and glassy you could cut a stone from it; a large face provides a window into the interior and a good display face. Old material mostly from the 1950s and 60s, hard as heck to get even within san diego these days. 3 x 2 x 1.6 cm
