The role of strain and temperature is critical inside the development of diamonds. Diamonds are fashioned deep inside the Earth’s mantle, where by the strain and temperature are really higher. The disorders required for diamond formation incorporate high tension, significant temperature, plus a source of carbon.

The value of colored diamonds relies on the intensity, purity and quality of their coloration. Those which has a saturated, vivid colour are termed "fancy-shade diamonds" or "fancies". On average, only one diamond in 10,000 has a shade that earns the "extravagant" designation.

Diamond check here simulants are elements that seem like diamond, but they may have distinct chemical compositions. Diamond simulants could be natural resources for example colorless zircon or sapphire.

on the 35% that did fluoresce, 97% had blue fluorescence of which 38% experienced faint blue fluorescence and 62% experienced fluorescence that ranged from medium to very sturdy blue. Other colors diamonds can fluoresce are environmentally friendly, yellow, and red, but are incredibly rare and are occasionally a mix of the colours such as blue-inexperienced or orange.

Slash: the standard of design and craftsmanship Utilized in slicing a diamond is what establishes its appearance.
