What Are The Different Grades Of Lab Grown Diamonds?

Lab grown diamonds are just as valuable as natural diamonds, but you may not know which grade of diamond your lab-grown diamond belongs to. There are four grades of lab grown diamonds, A through D, with the A being the most expensive and the D being the least expensive. The grading process assesses how pure the lab-grown diamond is and the quality of its cut.


The Gemological Institute of America (GIA) graded lab grown diamonds to range from colorless to light yellow. Lab-grown diamond retailers grade their inventory using GIA’s scale and categorize them as colorless, near colorless, faint yellow or fancy vivid yellow. Fancy vivid yellow has more white than a colorless diamond while faint yellow has very little white in its hue. There is no grading standard for CVD diamonds because they aren’t created by an outside party. CVD diamond manufacturers don’t use traditional grading scales as GIA does for natural diamonds.


The biggest challenge that faces Lab Grown Diamonds is how to make them look as good, if not better than their natural counterparts. But here’s where a great CVD diamond manufacturer can help. A clear and visually appealing stone will be worth a lot more than an opaque diamond, even if it’s cheaper. For example D E F VVS1 VS2 SI1/SI2 I1/I2 VS1+ SI1+ I1+. As you can see, getting down into all those details means that only a skilled gemologist or jeweler who has experience with lab grown diamonds should be grading your stones .


Lab grown diamonds are available in more shapes than natural mined diamonds and, depending on your priorities, can be just as beautiful. But most consumers don’t understand that there is a difference between them, let alone what those differences mean. In addition to cuts like round, oval and cushion that are available in both natural and man-made gems, a CVD diamond manufacturer also offers fancy cuts that were previously only possible through mining. These include trillion cut diamonds or hearts and arrows cut rocks. A Lab Created Diamond Manufacturer may also be able to make your shape if you desire it – even if it doesn’t yet exist in nature.

Carat Weight

Depending on where your diamond is manufactured, carat weight may not be used at all. However, a rough equivalent in terms of size can be given based on the manufacturer’s grading system.
