A chemically pure and structurally excellent diamond is beautifully clear without hue, or color. On the other hand, in reality most gem-sized pure diamonds are imperfect. The colour of a diamond can be impacted by chemical impurities and/or structural defects from the crystal lattice. With regards to the hue and intensity of the diamond's coloration, a diamond's colour can possibly detract from or increase its value.

In the nineteen fifties, new ways of diamond formation ended up identified on this planet's surface area. Experts ended up ready to create the temperature and strain disorders necessary to make diamonds within a lab.

Diamond unit cell, exhibiting the tetrahedral composition The most typical crystal framework of diamond is termed diamond cubic. It really is shaped of unit cells (begin to see the figure) stacked with each other. Even though there are eighteen atoms inside the figure, Every single corner atom is shared by eight device cells and each atom in the middle of the confront is shared by two, so there are actually a total of 8 atoms for each unit cell.[sixteen] The duration of both sides of your device mobile is denoted by a and is also 3.567 angstroms.[seventeen]
