Similarly, natural diamonds usually have minor imperfections and flaws, such as inclusions of foreign material, that are not seen in synthetic diamonds. Screening devices based on diamond type detection can be used to make a distinction between diamonds that are certainly natural and diamonds that are potentially synthetic.
Natural blue or blue-gray diamonds, common for the Argyle diamond mine in Australia, are rich in hydrogen; these diamonds are not semiconductors and it is unclear whether hydrogen is actually responsible for their blue-gray color. [21] Natural blue diamonds containing boron and synthetic diamonds doped with boron are p-type semiconductors.
However, in reality most gem-sized natural diamonds are imperfect. The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice. Depending on the hue and intensity of a diamond's coloration, a diamond's color can either detract from or enhance its value.

Synthetic diamonds, also referred to as lab-grown diamonds, are created using advanced technological processes such as High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). These methods result in diamonds that are chemically and physically identical to natural diamonds , offering the same brilliance and durability.
A situation that arises as a result of this is the exploitation of natural resources and labor within gemstone mining operations. Many mines, particularly in developing countries, face challenges such as inadequate safety measures, low wages, and poor working conditions. [ 49 ]
Oldenlandia corymbosa, commonly known as flat-top mille graines or diamond flower, is a species of plant in the family Rubiaceae. [1] [2] It is an annual herb with ascending or erect stems which are 4-angled. [3] Its genome size is 273.7 megabase pairs. It is a commonly used herb in China and India for treating sore eyes, anthelmintic ...
