- Are lab diamonds real diamonds?
- While lab diamonds are grown in a lab over the course of weeks or month, lab grown diamonds are every bit as real as natural, mined diamonds according to the U.S. Federal Trade Commission. In 2018 the FTC declared that “these stones have essentially the same optical, physical, and chemical properties as mined diamonds. Thus, they are diamonds.”
- How are lab grown diamonds made?
- Laboratory-grown diamonds, also known as man-made diamonds or simply “lab diamonds”, are grown in a highly controlled environment that seeks to replicate the growing process that occurred in nature billions of years ago when the earth was a very different place. Today, scientists have developed two main techniques for creating lab diamonds which we’ll outline further below, namely High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
- High Pressure-High Temperature (HPHT) uses extremely high pressure (about 1.5 million pounds per square inch or the weight of two Empire State Buildings) coupled with incredibly high temperatures (up to 1,500 degrees Celcius or about 25% as hot as the surface of the Sun). The conditions are created using various types of laboratory machinery. By placing a small diamond “seed” and carbon inside this environment of extreme pressure and temperature, the carbon transforms into a diamond (diamond is formed by a special configuration of carbon atoms in nature as well).
- CVD diamonds begin with diamond seeds that are placed in a vacuum-sealed plasma reactor and exposed to a carbon-rich gas under extreme heat and pressure. The gas is then ionized (a process by which an atom acquires a negative or positive charge by gaining or losing electrons), breaking the molecular bonds so that the carbon atoms are free to attach themselves to the diamond seeds and begin to organize themselves into a larger diamond, layer by layer
- Does the StoneAlgo Cut Score apply to Lab Grown Diamods?
- Yes! The Cut Score is calculated in the exact same manner for Lab Grown as it is for Natural diamonds. Look for the Cut Score on all of our Round diamond details pages and within the search results for Round diamonds.
- Does the StoneAlgo Visual Carat apply to Lab Grown Diamonds?
- Yes! We calculate the VIsual Carat weight for all Lab Grown diamonds displayed on StoneAlgo. This measurement is really important when trying to determine just how big a diamond will appear. Look for the Visual Carat on all details pages and on all cards within our search results.
