Material properties of diamond Material properties of diamond Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. Diamond is an optically isotropic crystal that is transparent to opaque. Diamond is the hardest naturally occurring material known. Yet, due to important structural weaknesses, diamond's toughness is only fair to good. The precise tensile strength of diamond is unknown, however strength up to 60 GPa has been observed, and it could be as high as 90–225 GPa depending on the crystal orientation. The anisotropy of diamond hardness is carefully considered during diamond
Crystal Light Crystal Light launched Pure Fitness, a "naturally-sweetened" low-calorie fitness drink mix which is sweetened with sugar and Truvia, a sweetener derived from the stevia plant. It is currently sold in "On The Go" packets. In 2011, Crystal Light Pure Fitness was renamed Crystal Light Pure, and three additional flavors were introduced. In April 2012, several Crystal Light varieties were added to the line of sodamix syrups for SodaStream home soda makers.
