Ziegler gives us Valrhona, a French chocolate made with a high proportion of criollo beans; Ziegler describes it as not sugar sweet, but flower sweet, and once Ziegler puts it into words, I can taste the flower sweet, just as I could taste the raisiny aftertaste..
Diamond is the hardest naturally occurring mineral, topping Mohs' Scale of Hardness with a relative hardness value of 10.Diamond is a polymorph of the element carbon, and graphite is another. While the two share the same chemistry, C (elemental carbon), they have very different structures and properties.iamond is the hardest naturally occurring mineral, topping Mohs' Scale of Hardness with a relative hardness value of 10.
Diamond is the ultimate gemstone, having few weaknesses and many strengths. It is well known that Diamond is the hardest substance found in nature, but few people realize that Diamond is four times harder than the next hardest natural mineral, corundum (sapphire and ruby).But even as hard as it is, it is not impervious. Diamond is transparent, Graphite is opaque. 2  Diamond crystallizes in the Isometric system and graphite crystallizes in the hexagonal system. 3  Somewhat of a surprise is that at surface temperatures and pressures, Graphite is the stable form of carbon.
