Get to Know as-grown Diamonds

Here is a phrase of significant importance when buying lab-grown diamonds. Often, this can determine the level of purity of the gem.

As-Grown diamonds are created using a process similar to what natural diamonds go through. It is called High-Pressure High Temperature (HPHT). 

In most cases, this will result in colorless diamonds.

When you are looking through the certificate for the diamonds you want to buy, search for the phrase as-grown diamonds or HPHT

The opposite of these would be Chemical Vapor Deposition (CVD) this is an alternative process to create lab-grown diamonds and most of the time it will result in brownish or yellowish diamonds.

CVD diamonds however can undergo treatment that will make them look brighter. This is a process called post-growth treatment.

But, as you buy LGD, do not get cheated by having to pay more for CVD that are being passed off as as-grown diamonds. The certificate should indicate which of the 2 they are. 

Color Tint in Lab-Grown Diamonds

It may surprise you to discover that almost all diamonds have a tint. However, the higher grade LGD do not have tints visible to the naked eye. During the process of HPHT, a chemical agent called Boron gets trapped within the gem and this can give the blue tint within LGD. However, you will not easily see that tint unless you are a trained eye.

Meanwhile, the process of CVD often results in nitrogen getting trapped in the stone and that presents a yellow tint.

Now, Lab Grown Diamonds are graded based on the tint they possess. Knowing about that tint can help you negotiate a good price for your gem. These are the different Grades.

Colorless: These lab-grown diamonds are the highest grade of diamonds. Grade D is the supreme grade. Here, the diamond has absolutely no tint even when inspected under bright light or when magnified. Closely graded in the colorless category are grades E and F. to an ordinary person there may seem like there is no difference between all 3 grades. Gemologists however can use a magnifying glass to identify the differences.

Nearly Colorless: These LGD are graded as G to J. To the naked eye, they may appear colorless but a closer examination can reveal the blue or yellowish tint in them. Within this category, G to H grades are far superior to I and J. The inferior grade can show a mild tint in certain lights when viewed with the naked eye in comparison with G and H which will need professional scrutiny to reveal the tint. HPHT diamonds will look more colorless than CVD.

Faint Tint: This includes diamonds in the K to M grade. There is a hint of color within them even when you do not look so critically at them. In some cases, people prefer these diamonds because the faint tint gives them a unique look. They may be referred to as having a warm gold look that appeals to the eye.

Very Light Tint: This grade is from N to R. Most experts will discourage you from buying such diamonds. The yellow or brown is pronounced and you would easily notice it. However, if you are on a tight budget it likely will be something you can afford and pass off as a colored diamond among people who do not know much about grades and colors.
