Main diamond producing countries. Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.Diamond as a form of carbon is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water.
Diamond is a good electrical insulator, having a resistivity of 100 GΩ⋅m to 1 EΩ⋅m [32] (1.0 × 10 11 – 1.0 × 10 18 Ω⋅m), and is famous for its wide bandgap of 5.47 eV. High carrier mobilities [33] and high electric breakdown field [34] at room temperature are also important
Diamonds are such a highly traded commodity that multiple organizations have been created for grading and certifying them based on the "four Cs", which are color, cut, clarity, and carat. [1] [2] Other characteristics, such as presence or lack of fluorescence, also affect the desirability and thus the value of a diamond used for jewelry.
A real diamond is just that: one that’s originally found in nature. However, Jhaveri tries to use the term ‘natural’ when describing them, saying that lab-grown diamonds are just as real as ...
The simulants imitate the look and color of the real stone but possess neither their chemical nor physical characteristics. In general, all are less hard than diamond. Moissanite actually has a higher refractive index than diamond, and when presented beside an equivalently sized and cut diamond will show more "fire".
Fake diamonds are often indistinguishable from authentic diamonds to the naked eye. But it turns out that telling the difference between a fake diamond and a real diamond is easier than you thought.
