Extended data:
Diamonds come in various colors, ranging from colorless to black, of which colorless is particularly preferred. They can be transparent, translucent or opaque. Many diamonds are yellow, mainly because they contain impurities. Diamonds have very high refractive index and strong dispersion, which is also the reason why diamonds reflect colorful flashes.
Diamonds emit blue-green fluorescence under X-ray irradiation. Primary diamond ore only occurs in kimberlite cone or a small amount of K-Mg lamprophyre. Kimberlite is their parent rock, and diamonds from other places are transported by rivers and glaciers.
Diamonds are generally granular. If the diamond is heated to 1000℃, it will gradually become graphite.
In diamond crystal, carbon atoms are interconnected by tetrahedral bonds, forming an infinite three-dimensional skeleton, which is a typical atomic crystal. Each carbon atom forms a valence bond with the other four carbon atoms through SP3 hybrid orbitals, forming a regular tetrahedron.
Because the C-C bond in diamond is very strong, all valence electrons participate in the formation of valence bond, and there are no free electrons, so diamond is not only hard, but also has a very high melting point and is not conductive.
In industry, diamonds are mainly used to make probes and abrasives for drilling, and also used to make high-grade decorations such as hand ornaments with complete shapes, which are very expensive.
