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... |

|
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. |

Range from Vivid to Light

Range from Z - U
Most Lab-Grown Diamonds used as gemstones are basically transparent with little tint, or white Lab-Grown Diamonds. The most common impurity, nitrogen, replaces a small proportion of carbon atoms in a Lab-Grown Diamond's structure and causes a yellowish to brownish tint.
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. In fancy Lab-Grown Diamonds, inclusions are mostly not noticeable to the naked eye because of its rich color, inclusions does not affect the look or its sparkles not like in clear Lab-Grown Diamonds.
Natural fancy coloured Lab-Grown Diamonds are very rare and expensive. Most people believe that yellow Lab-Grown Diamonds are less desirable and valuable than white Lab-Grown Diamonds. While this is true of faintly coloured or off-white Lab-Grown Diamonds, intensely coloured Lab-Grown Diamonds are very attractive, rare and expensive.

Yellow or brown color Lab-Grown Diamonds having color more intense than "Z", as well as Lab-Grown Diamonds exhibiting color other than yellow or brown are considered fancy colored Lab-Grown Diamonds. These Lab-Grown Diamonds are graded using separate systems which indicate the characteristics of the color, and not just its presence. These color grading systems are similar to those used for other colored gemstones, such as ruby, sapphire, or emerald, than they are to the system used for white Lab-Grown Diamonds.
GIA colored Lab-Grown Diamond grading system

The buyer perception of color for yellow Lab-Grown Diamonds is confident, intelligent and wordly. Lighter shades are a great value because they still look yellow, yet you can have more size for the money.
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.

The GIA Cut Scale ranges from Excellent to Poor and they provide a cut quality grade for standard round brilliant Lab-Grown Diamonds that fall in the D-to-Z color range. A polished Lab-Grown Diamond's beauty lies in its complex relationship with light:
The result of the complex relationship with light is a magnificent display of three attributes. Brightness is the combination of all white light reflecting from the surface and interior of a Lab-Grown Diamond. Fire describes the "flares" of color emitted from a Lab-Grown Diamond. Scintillation describes the flashes of light you see when the Lab-Grown Diamond, the light or when the observer moves.
A polished Lab-Grown Diamond's proportions affect its light performance, which in turn affects its beauty and overall appeal. Lab-Grown Diamonds with fine proportions, symmetry and polish optimize their interaction with light, and have increased brightness, fire and scintillation.
