| Full boules. This is an incredible, once-in-a-lifetime find. Large, complete 6" diameter silicon boules, not cut up, but complete from top to bottom just as they grew from the vat. They are said to have come from the back room of a mineral dealer's shop in California, discovered after the death of the shop owner. All trace of their history has thus been lost. The cut-off tops of boules like this are not too hard to find, but complete boules are not commonly seen. They are too valuable for cutting up into chip wafers for anyone to consider leaving them in complete form. These look pretty irregular, and my theory is that there's something wrong with them that makes them unsuitable for chip making. Maybe the purity wasn't good enough, or maybe the diameter profiles came out too wild. It's amazing to think that these 40-pound monsters are each one single crystal all the way from the top to the bottom. No, they are not for sale.
