Buying a Lab Grown Green Diamond
Buying a Lab Grown Green Diamond
Buying a lab grown green diamond is a great idea if you want to get a diamond that is beautiful and will last a long time. The process of growing a diamond is called Chemical Vapor Deposition (CVD), and it can be very costly, but it’s a very good option if you’re looking for a diamond that isn’t a traditional color. This type of stone can come in a variety of colors, including white, pink, blue, yellow and green. This type of stone is much more affordable than traditional stones, and it’s also easier to clean and care for.
High-Pressure High-Temperature (HPHT)
Using a diamond from the High-Pressure High-Temperature (HPHT) process is a more eco-friendly option for jewelry buyers. Unlike the process used to make Natural-Origin diamonds, this process uses a lot less pressure and heat.
This method uses a growth chamber, which contains a tiny diamond seed and highly refined graphite. The growth chamber is sealed and surrounded by high pressures. The pressure promotes the growth of crystal structures. The chamber is then cooled. The elements within the growth chamber melt and reform over a few days.
Another popular process used to make synthetic diamonds is Chemical Vapor Deposition (CVD). This process uses lower temperatures and pressure than the HPHT method. The diamonds produced by CVD are typically black in color. However, they are still high color and clarity.
Both processes are intended to produce high-quality diamonds that are free of inclusions. However, it is difficult to tell a lab-grown diamond from a natural diamond, because they are so similar in composition. The only way to know for sure is to ask the lab about their official certification.
The growth cycle of a HPHT diamond starts with a small seed of diamond material. The seed is then placed in a chamber, which contains carbon and a catalyst. It is then left for many days to grow into a diamond.
Once the cycle is complete, the growth cell is removed from the machine and the new rough diamond is extracted. It is then cleaned before it is polished and cut. The new rough diamond is typically sold at the same price as a mined diamond. The cut and clarity are also considered when pricing a lab-grown diamond.
Chemical Vapor Deposition (CVD)
WD Lab Grown Diamonds is the market leader in Chemical Vapor Deposition (CVD) laboratory grown diamonds. They produce diamonds for jewelry, scientific and industrial markets. They have laboratories in Chicago and Washington, D.C. They are also the first diamond company worldwide to be certified Climate Neutral.
The process of growing CVD diamonds relies on a unique technique. This process replicates the crystallization of carbon over a diamond seed inside a vacuum chamber.
The process begins with a diamond plate being heated to 800 degrees Celsius. Then a vacuum is created in the chamber using a rotary pump. The vacuum chamber is filled with hydrogen-carbon gas and oxygen.
The carbon-rich gas then attaches to the diamond seed and breaks the molecular bonds. The process is repeated over a period of weeks. The final diamond is then grown at the desired temperature and pressure.
The growth process is controlled and monitored by specialists. The process seed can be a small slice of diamond or graphite. It is placed in the chamber at a high vacuum. The size of the chamber will determine how many weeks it will take to finish a single diamond.
The growth process can be heated with chemical activation or thermal activation. Gases can also be heated by using a torch.
High pressure, high temperature (HPHT) is another technique used to produce lab grown diamonds. The process requires a large vacuum chamber filled with a hydrogen-carbon gas mixture. It can also be a source of ionized plasma.
The HPHT process can turn diamonds yellow, pink, orange or green. This process can also create colourless diamonds.
HPHT Faint Blue/Blue Nuance
During the growing process of a diamond, it is exposed to raw elements like nitrogen, oxygen, and boron. Boron is a chemical that makes diamonds electrically conductive. Boron impurities in diamonds can give a diamond a bluish hue.
Boron can also make a diamond read as moissanite on a cheap diamond tester. It can be difficult to remove boron. In addition, removing boron is expensive. It is a good idea to choose a diamond that has been grown without boron.
During the growing process, boron is introduced to speed up the process. During the growth phase of a diamond, the crystal lattice is exposed to high temperatures. This causes boron to spread across the surface of the diamond. It is called the Blue Nuance effect. It is also the reason for the blue tint in HPHT diamonds.
It is important to note that the Blue Nuance effect isn’t always present in HPHT diamonds. In fact, some synthetics have been accidentally contaminated with boron during the growth process.
The Blue Nuance effect isn’t as prevalent in HPHT grown diamonds as it is in mined diamonds. Several natural diamonds have a blue tint, but they are rare.
It’s important to note that a diamond with a blue tint will display a different color when exposed to sunlight. Blue diamonds will also display a different color when removed from their source.
In addition to the blue tint, HPHT diamonds will also display phosphorescence. Phosphorescence is a cool phenomenon that can last seconds to minutes. It is often used to distinguish natural and lab grown diamonds.
In addition to phosphorescence, some lab diamonds will display a grey undertone. These undertones are not easy to detect in 360 degree videos. However, high-quality photos will reveal the strain lines.
GIA color-grading system for fancy colored stones
GIA’s color-grading system for fancy colored stones is an effective way to evaluate a diamond’s color. Although it isn’t 100% accurate, it does give a rough idea of what the stone will look like. In addition, the scale is universal and applies to any color. The system also allows graders to describe the degree of hue, tone, and saturation in a diamond.
Color distinctions between diamonds can make a big difference in a diamond’s value and quality. However, these subtle distinctions are impossible to notice unless you’re trained.
The Gemological Institute of America (GIA) has a color-grading system that can be used to grade any color. The scale begins with the letter D, representing colorless diamonds, and continues through Z, representing more colored diamonds.
The most important component of the GIA color grading system is saturation. Saturation refers to the depth of color, as well as the strength of the hue. The higher the intensity of a hue, the higher the value of a fancy colored diamond.
The GIA color-grading scale begins with a colorless diamond and ends with a colored diamond. It is a scale for white diamonds, but can be applied to any color.
There are nine grades that make up the GIA color-grading scale. Each grade has a defined range of color appearance. In addition, there is a separate scale for fancy colored diamonds.
Fancy colored diamonds are special diamonds with a unique color pattern. Colors can range from green to blue to purple. Some fancy colored diamonds are even described as having a tint of yellow. These diamonds are more rare and therefore more expensive than colorless diamonds.
