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.
Corundum, naturally occurring aluminum oxide mineral (Al2O3) that is, after diamond, the hardest known natural substance. Its finer varieties are the gemstones sapphire and ruby, and its mixtures with iron oxides and other minerals are called emery. 1  Corundum in its pure state is colourless, but the presence of small amounts of impurities can impart a broad range of hues to the mineral. Ruby owes its red colour to chromium, sapphire its blue shades to the presence of iron and titanium; most corundum contains nearly 1 percent iron oxide.
