Description |
|
D |
This is the highest Color Grade and absolutely colorless. Price is high due to its rarity but hey, if you can afford it, go ahead... |
|
E |
It is colorless to the unaided eye. Only a trained gemologist using special equipment can determine any color difference between a D- and an E-color Lab-Grown Diamond. This is considered a rare Lab-Grown Diamond. |
|
F |
Colorless, a slight color detected by an expert gemologist, but still considered a Colorless grade and a high-quality Lab-Grown Diamond. This will work with any white gold or platinum. |
|
G |
This Lab-Grown Diamond is nearly colorless with an extremely faint tint that is noticeable only to a trained gemologist. G-color Lab-Grown Diamonds are ideal for beautiful jewelry because they offer an outstanding value at a lesser price compared to the colorless grades, but it still appears to be colorless when mounted. |
|

This has an advantage of exceptional value due to the near colorless range. This Lab-Grown Diamond will appear colorless when mounted on a very slight tint of color. |
|
I |
Near-colorless with a slightly detectable tint and is an excellent value. |

This grade begins to show a tint of color when they are of half carat or more. If mounted in white color metals, they may appear as a J-grade. |

Beautiful yellow Lab-Grown Diamonds exist in tones from light yellow to fancy intense vivid yellow, also named Canary Yellow, depending on the concentration of nitrogen when the crystal is formed. Yellow Lab-Grown Diamonds are more desirable than white Lab-Grown Diamonds, due to their warm color.

Gran Colorimeter
Color can also be determined using a device called the Gran Colorimeter, manufactured by Sarin Technologies. It measures from D to Z to Fancy Intense with an accuracy within ±½ of a color grade on loose stones from 0.25 to 10 carats (as low as .15 carat or as high as 20 carats with reduced accuracy), and you can specify which grading scale it should use (GIA, GEM, IGI, AGS, HRD, and others). The accuracy is within ±1 color grade for mounted stones. If you Lab-Grown Diamond is a "G" color it will tell you whether it's a "high G" or a "low G". The Gran colorimeter was first developed by Paul Gran in 1972 at Gran Computer Industries Ltd.
