Near Colorless Diamonds
Near colorless diamonds comprise the letters G, H, I & J, which are diamonds that, face up in the mounting are still "colorless" or white diamonds. If I were to put a "G" or an "H" color next to an "E" or an "F" the average laymen will not know the difference. To really see any kind of a difference is to place em against that flat white background. The three most common colors that diamond decreases to are either yellow, brown or gray with yellow probably being the most popular. Brown or light brown stones are showing up more and more and are being advertised as "champagne" diamonds. Don't get fooled they're even cheaper. Here's G, H, I & J alongside each other.
Here are the colorimeter results of the near colorless diamonds we'll be using in this study.
Ok ... these comparisons are going to be made alongside a "D" color, both face down and face up against a flat white background under northern daylight fluorescent lighting which is perhaps the most critical view you'll ever see of diamond color. Face up and mounted in a ring it's almost impossible to see these differences.
These 2 shots of a G next to a D and you can barely make out the faint nuances that exist between colorless vs near colorless.
You can barely make out the hint of warmth in the G color. This is only detectable because of the grading environment. In a ring its almost impossible to see however I have met some very sharp eyed ladies who could.
Notice the ever so faint warmth of color in the J? Generally this is only visible against the flat white background and even then it really is very "faint". It's not like comparing a white diamond to a yellow diamond. You will see saturation of this tint start to increase as we go further on down the scale.
All of the colors covered to this point (D-J) are considered to be "white" diamond and do face up beautifully after being set. There are a couple of factors that can help neutralize the appearance color which we will cover in more detail as we progress.
After the colorless and near colorless diamonds comes what is referred to as diamonds with a "Faint Tint". Let's take a peek at those.
