how this element can be identify?
Optical techniques can distinguish between natural diamonds and synthetic diamonds. They can also identify the vast majority of treated natural diamonds.

describe carbon in covalent bonds and the importance of it It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds what are the characteristics of this element? Carbon is the sixth element, with a ground-state electron configuration of 1s2s2p, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements. where this element can be found in the earth? Earth's crust what are its most common allotropes? Amorphous carbon, graphite, and diamond how did this element get its name? The English name "carbon" comes from the Latin "carbo" for coal and charcoal, whence also comes the French "charbon", meaning charcoal. what is the last allotrope? Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. what can you tell about its electrical conductivity properties? Blue diamonds are natural semiconductors, in contrast to most diamonds, which are excellent electrical insulators. what are its surface properties? Diamonds are naturally lipophilic and hydrophobic, which means the diamonds' surface cannot be wet by water, but can be easily wet and stuck by oil.

Diamond [SEP] Identification
This test takes about two to three seconds. Whereas the thermal probe can separate diamonds from most of their simulants, distinguishing between various types of diamond, for example synthetic or natural, irradiated or non-irradiated, etc., requires more advanced, optical techniques. Those techniques are also used for some diamonds simulants, such as silicon carbide, which pass the thermal conductivity test. Optical techniques can distinguish between natural diamonds and synthetic diamonds. They can also identify the vast majority of treated natural diamonds. "Perfect" crystals (at the atomic lattice level) have never been found, so both natural and synthetic diamonds always possess characteristic imperfections, arising from the circumstances of their crystal growth, that allow them to be distinguished from each other.
