Oxymoron
... burned the hair without oxygen ... ???
A synthetic diamond company has transformed 10 strands of Beethoven's hair into a "Fancy Blue" 0.56 carat gem expected to sell for up to $1m on eBay. According to the Telegraph, LifeGem obtained the sample of the composer's locks from the University Archives in Connecticut, which boasts barnet samples from a raft of celebs …
It is perfectly possible to burn something without oxygen as only fire needs oxygen. Simply raising the temperature in a vacuum (perhaps by heating the walls of the container - in a similar way to cooking on a hotplate) would be enough to reduce the hair to carbon ash, thus allowing safe extraction.
Not that we really care about where the atoms came from, but...
1 carat = 0.2g, so the 0.56 ct diamond weighs 1.12g, and is to all intents and purposes pure carbon. But Ludwig's barnet yielded only 0.113g of soot, and that was going to be used in *three* diamonds. If they're all the same size, that means that the Beethoven jewel is in fact only three percent Genuine Genius Fur. I expect to see the ebay auction accurately labelled.
