金刚石

It is not known how rare this resemblance is, or whether it is most often seen in inclusions of silicates such as garnet, whose crystallography is generally somewhat similar to that of diamond; but when present, the resemblance is regarded as compelling evidence that the diamonds and inclusions are truly congenetic.

现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的硅酸盐内含物中，而这类物质的晶体结构普遍地在某种程度上类似于金刚石的晶体结构。但一旦存在，这种类似就被视作极有说服力的证据，证明金刚石与内含物确是同源的。

The carbons in explosives are decomposed into gas-like carbon atoms in the detonation reaction zone, then unoxidized carbon atoms coagulate into carbon liquid droplets and finally consolidate into solid diamonds The new mechanism differs from one conclusion that carbons of explosives are at first transformed into solid graphites, then into diamonds, and also differs from the conclusion that gaseous carbons coagulate into liquid droplets in the reaction zone, then crystalize into diamonds in Taylor rarefaction wave zone.
