|Electrochemically grown crystals.|
These crystals were reported to have been grown in a factory some time ago. I don't know much more about them, but they are beautiful, shiny, and titanium-like. A few are about an inch long, the rest crumbled.
I purchased a small quantity in 2002, and then three pounds in 2003, one pound for me and two for the museum displays I have been working on with The Red Green and Blue company. As of mid-2003 the seller reports having about 20 pounds left: When that is gone, there may be no more of these available.
