Welcome to our Tutorial on Diamond Color!
First we will start with the basics from GIA and work our way into some more details that I believe you will not only find helpful but also pertinent to your buying decision.
Ok... nothing like starting from scratch.
So what exactly is diamond color and what causes it?
Very simply put "color" in diamond is the relative body color of the gem material which is graded on a scale, based on the alphabet starting at the letter D and graduates all the way to the letter Z. The scale is broken up into 5 categories depicted in the slider chart below. The color most often presented in diamond is "yellow" as you'll see in the charts/videos but the most popular body colors of diamond can vary. Yellow first, brown second and then gray. These tonal differences can impact value.
The "yellow" tone is caused by the presence of nitrogen in the earth at the time the carbon is crystallizing. The lack of nitrogen in the earth causes the diamond to be more colorless. Naturally, more nitrogen = more yellow. The "brown" tone is caused from the presence of nickel and the "gray" tones by hydrogen.
In brief, if you're looking for "white" diamond you'll want to keep within the D-J color range. For people who are extremely color sensitive then you may want to stick D-H. If you don't mind a faint tint you can consider K-M. Lower than that and the tint really becomes more notable. Watch the videos below this chart to see what I'm talking about.
The subject of diamond color, while easy to grasp is often misunderstood or not seen and presented accurately when you go to view diamonds in a local jewelry store. Sometimes learning about what somethingisn't helps us to better understand what it actually is. I've shot a video on this very subject which will help to clear up that confusion as you venture out and look at diamonds. Then I will show you with greater detail what it actually is.
In this video I'm going to take you into the laboratory with me as we examine diamod colors D-O face down as well as face up against a flat white background in GIA's official lighting for grading color which I've captured all on video for your learning experience. It is one of our more popular programs on the web today.
In our latest and perhaps most exciting installment we explore the factors that can make a diamond appear whiter than it actually is!
Now that we've covered the basics on Diamond Color we'd like to get a little more in depth and start by introducing you to one of the technologies we employ to check and grade color with the Diamond Colorimeter.
