Laboratory-grown diamonds undergo a rigorous grading process before they can be certified as natural or lab-grown. GIA diamond specialists analyze these stones to verify their identity and determine if any treatments have been applied. They look for florescence, phosphorescence, and inclusions, among other things. Afterward, they issue a Laboratory-Grown Diamond Report and laser-inscribe the girdle of the stone with its statement and report number.
Synthetic diamonds
Natural diamonds are formed in nature under very high pressure and temperature. They are formed billions of years ago in the deep earth and are brought to the surface through movement. Miners then excavate these diamonds and sell them to the public. In the 19th century, many scientists attempted to recreate this process, but none were successful. This is why synthetic diamonds are referred to as lab-grown diamonds.
HPHT
HPHT lab-grown diamonds are naturally formed diamonds laboratory grown diamonds which undergo a highly controlled process of heat and pressure in a laboratory. During this process, diamonds change from their brown tint to a white hue. This process is considered eco-friendly because it does not require the destruction of tons of earth. In contrast, diamond mining companies require the destruction of a huge quantity of land in order to find the diamonds that they sell. Thus, the process of HPHT laboratory-grown diamonds does not leave any traces of land mining scars.
CVD
Diamonds produced with CVD technology are often referred to as cloud inclusions. They are clusters of needles and pinpoints whose properties are derived from the diamond-growing process. These inclusions can be ionized and have distinctive features based on their composition. Unlike traditional diamonds, CVD lab-grown stones are transparent, so consumers are not required to purchase them in the dark to determine their origin.
Phosphorescence
Whether you want to invest in a new diamond engagement ring or simply wear it as a simple adornment, phosphorescence of laboratory grown diamonds is a critical attribute to consider. This spectral property produces an orange or red glow in dark situations, and it is often a surefire way to spot a lab grown diamond. Although this characteristic is very rare in natural diamonds, it can indicate a potential laboratory grown diamond. If you notice this phenomenon, you should immediately send the stone to a laboratory for testing.
Cost
The first major difference between mined diamonds and lab-grown diamonds is the cost. While a diamond mined from the ground is a lot more expensive than a lab-grown diamond, they are structurally the same. Moreover, the difference in price is not just the size of the diamond; it is also its clarity. Lab-grown diamonds are much cheaper because the growing process involves extreme heat and pressure that causes the carbon atoms to bond closer together. This process can be performed at a high-tech lab and it is more cost-effective as compared to natural diamonds.
Size
Unlike traditional diamonds, which can only be found in a few sizes, lab grown diamonds can be any size. Because of this, they are popular among jewelry buyers. These diamonds are not only affordable, but they can also come in a variety of sizes, including those that are not available in natural diamonds. The following are some of the factors to consider when choosing a laboratory grown diamond. Read on to learn more.
Quality
Laboratory grown diamonds have recently gained in popularity as an alternative to natural diamonds. This type of diamond is a cheaper alternative to natural diamonds, and the 4Cs of diamond quality are easier to measure. In addition to being more affordable, these diamonds are often available in vibrant colors, which are rare in natural diamonds. In addition, they are often ethically sourced and are environmentally friendly. Therefore, laboratory grown diamonds are an excellent alternative for those who are concerned about the environment and want a better quality stone.
