G color diamonds are a good choice for any engagement ring regardless of the diamond's shape or the setting's color (gold, platinum, etc.). G color diamonds are the best, whitest, and most expensive of the Near Colorless class of diamond color grades that includes H, I, and J colors as well.
G/Si quality diamonds are an excellent choice for engagement rings. This is a bright white diamond that has no visible inclusions. The colour quality is G, meaning this is a bright white diamond. Expert knowledge is needed to identify any colour tint.
Round G Color Diamond
Not only is it universally flattering on all finger shapes and sizes, but it also allows a high degree of light to travel through the diamond, making it as sparkly as possible. Since it reflects more light, a round cut can conceal any traces of yellow.
The short answer is: No. A G-color diamond faces up icy-white and almost identical to colorless D-E-F stones. In fact, if you were to see a standalone G diamond without any side by side comparisons to other stones, they would look completely colorless.
So, in short, a J diamond should be the best color for most people. A J diamond with an “excellent cut” is also far more preferable than a G diamond with a “poor cut”.
G color diamonds are a good choice for any engagement ring regardless of the diamond's shape or the setting's color (gold, platinum, etc.). G color diamonds are the best, whitest, and most expensive of the Near Colorless class of diamond color grades that includes H, I, and J colors as well.
Diamonds are graded on a scale starting with D and ending with Z. D diamonds are the most colorless. D, E, and F color diamonds are “colorless.” G and H still look colorless and are the best value.
In a VS1 diamond, the imperfections are smaller and harder to see than those in a VS2. Diamonds with a VS1 clarity grade will always be eye-clean. That means they'll have no imperfections visible to the naked eye.
Because diamonds reflect white light, colorless diamonds produce the best sparkle and fire. In fact, the more color a diamond has, the less likely it is to reflect white light. And as a result, will produce less sparkle. A D-color diamond is the highest quality, and will offer the greatest sparkle.
If your white diamond has developed a yellowish tint, you can blame dirt or other substances. Even a light layer of dust or dirt can make a colorless diamond look yellow. Other possible culprits include hairspray, soap, and makeup. These substances can build up over time, making it look stained and discolored.
The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of colors onto other surfaces. A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.
Ideally, pair diamond colors of D, E, or F with clarity grades of F (flawless), IF, VVS1, or VVS2, especially if the diamond matches or exceeds one carat in size. Diamond color of G, H, or I should be paired with VVS2, VS1, or VS2 clarity. Pair J, K, and L with SI1 or lower.
Contrast = More Visible Color
Any slight trace of visible color in your diamond is likely to be more noticeable in white gold than it would be against yellow gold, because of the contrast created between the two.
Fancy vivid yellow diamonds are extremely rare and can be much more expensive than pure colorless white diamonds. Lower grade white and faint yellow diamonds share similar pricing. Fancy vivid yellow diamonds are graded as vivid yellow or brownish yellow in hue and have an intense saturation.
Champagne, gray, salt and pepper, chameleon, and black diamonds are actually less expensive than their white counterparts! All the other colors, however, are more expensive.
The highest color grade for a diamond is “D”. “D” color diamonds are very rare and not commonly found in traditional jewelry. Most diamonds used in jewelry have a slight presence of color. It is possible for diamonds to have a very high concentration of desirable color.
You see, diamonds are a magnet for grease/oil as their surfaces muck up easily. A dirty stone doesn't sparkle because light simply can't enter the diamond and causes it to appear dull.
Clarity is more important in shapes like emerald, princess, and asscher. Colour is important for cushion, radiant, pear and oval. Generally speaking, as long as you choose an eye-clean diamond, your diamond will still look beautiful in terms of clarity.
Cut is the most important determinant of the overall appearance of a diamond. No Clarity grade can help a poorly cut diamond; however, an excellent cut diamond can have a lower color (G-H) or clarity (SI1-SI2) and still look quite beautiful due to its superior ability to create sparkle and brilliance.
VS2 clarity means that, under 10x magnification, inclusions are almost always easily noticeable. A VS1 grade, on the other hand, means that inclusions are only somewhat noticeable. In essence, the difference is that inclusions in VS2 diamonds are slightly easier to detect using magnification tools.
I color diamonds are the third grade of “near colorless” diamonds, the color grades G - J. Near colorless diamonds like I color are the most popular choice for engagement ring jewelry since they balance both beauty and affordability (relatively speaking of course).
For diamonds over 2 carats, a clarity grade of VS2 or higher is the safest bet for avoiding any signs of visible inclusions. In diamonds between 1 and 2 carats, clarity grades of SI1 or better will not have inclusions easily visible to the naked eye.
The I and J colored diamonds, while still in the near colorless range, will begin to show very very light tint of yellow or brown. Your eye may not even pick up on the shading, but the diamond may visibly look less bright than a diamond with a higher grade, such as F or G.
