Above: arguably the world's smallest item of quality gold jewelry, a 16-atom configuration newly created by scientists but not yet available in stores. As this article from the New York Times notes, 20-atom configurations of gold take a pyramidal shape, an array echoed in the golden sands of Egypt.
Below: a small, but not quite that small, merkaba from cosmic jeweler Ka Gold (HT: Jennifer Emick).
DA VINCI CODE EXTRA: click the pic for Ka Gold's explanation of the mystical merkaba and you'll see a rather familiar figure, pictured here in a more family friendly version!
