Diamonds are made out of pure, crystallized carbon. Carbon molecules in diamonds are arranged to create a very hard, clear, crystalline structure with a Mohs scale rating of 10. Diamond values tend to fluctuate depending on various grades of transparency and light refraction.

Common synthetic materials are nylon, acrylic, polyester, carbon fiber, rayon and spandex. Synthetic materials are made from chemicals and are usually based on polymers. They are stronger than natural and regenerated materials.

Synthetic oil, which is manmade in a laboratory as opposed to being derived from crude oil, is more stable at a variety of temperatures and has a more consistent molecular structure. Because of this, synthetic oil helps engines run cooler, provides better lubrication at higher temperatures and lasts

Synthetic oil is a motor lubricant that is not derived from common crude oil. The base of synthetic oil is made from synthetic stocks known as Polyalphaolifen.

Natural diamonds are formed deep within the earth, using heat and pressure found around 87 to 118 miles beneath the surface. Carbon compressed tightly together forms a crystal lattice, the purity of which determines colors in the diamond.

Synthetic elements are made by adding protons or neutrons to existing elements. A beam of subatomic particles is fired at an atom of an existing radioactive element. When this atom captures an extra proton, or captures an extra neutron and decays, a new element is formed.

Diamonds, which are one form of pure carbon, are created from intense heat and pressure that happen deep inside the earth over eons. In modern times, scientists have learned how to recreate this heat and pressure to make artificial diamonds.

Synthetic or artificial blood works primarily through passive diffusion. This process takes advantage of the tendency of a gas to move from areas of greater concentration to areas of lesser concentration until it reaches equilibrium. In humans, oxygen shifts from the lungs (high concentration) to th

Diamond is the hardest mineral on the Mohs scale of mineral hardness, with a rating of 10, and is four times harder than the next mineral on the chart, corundum, of which sapphire and ruby are varieties. The Mohs scale is the most common system used for this measurement. It is a relative scale, grad

Naturally black diamonds are extremely rare and can have a very high value, depending on the cut, color, clarity and carat size of the diamond. The most accurate way to learn the value of a black diamond is to have it appraised by a jewelry appraiser or a jeweler.
