Diamond cubic strong isotropic property. Namely, for any two vertices "x" and "y" of the crystal net, and for any ordering of the edges adjacent to "x" and any ordering of the edges adjacent to "y", there is a net-preserving congruence taking "x" to "y" and each "x"-edge to the similarly ordered "y"-edge. Another (hypothetical) crystal with this property is the Laves graph (also called the K crystal, (10,3)-a, or the diamond twin). The compressive strength and hardness of diamond and various other materials, such as boron nitride, is attributed to the diamond cubic structure. Similarly truss systems that follow the diamond
Crystal Head Vodka Crystal Head Vodka Crystal Head Vodka is a brand of vodka manufactured by Globefill Inc. in Newfoundland and Labrador, Canada. It was conceived and founded by actor Dan Aykroyd and artist John Alexander in 2007. The vodka is quadruple-distilled and seven times filtered, with the final 3 filtrations through Herkimer diamond crystals, which are actually a type of double-terminated quartz rather than diamond. The Crystal Skull bottle was designed by artist John Alexander and is manufactured by Milan-based glass-manufacturer Bruni Glass. Aykroyd and Alexander first conceived of the idea for Crystal Head Vodka in 2007. Due to the lack of
