Understanding the Diamond Color Scale
Today it’s hard to imagine buying diamonds without the 4Cs, the handy mnemonic device GIA created to describe diamond quality, and the familiar diamond color grades. But the diamond color scale is a relatively recent invention created in the 1950s by the Gemological Institute of America.
Understanding Diamond Carats and Diamond Size
The first thing we notice about a diamond engagement ring is its size. But diamonds are sold by weight, not size. Diamond carats are a unit of gem weight that’s equivalent to one-fifth of a gram. In other words, a five-carat diamond weighs one gram.

What Makes a Diamond Sparkle?
Icy white. Transparent as water. Harder than nails. Billions of years old. Diamonds are the most sought after gems on earth. But what really makes a diamond special is the way it handles light. That’s what makes diamond the king of bling. Nothing is as brilliant as a diamond. So what makes a diamond sparkle?
What You Need to Know About Buying Black Diamonds
Even if you know a lot about diamond quality, buying a black diamond is almost as opaque and mysterious as the inky gems themselves.In almost every way, black diamonds are the opposite of traditional colorless diamonds. They are colorless diamond’s goth cousin: dark instead of bright. Colorless diamonds are for everyone. Black diamond engagement rings are for women who aren't like anyone else: rebels, iconoclasts, and trendsetters.
Why Are Diamonds Expensive?
There’s no doubt about it. Diamonds are expensive. Diamonds cost more than gold or platinum. A lot more. So why are diamonds so expensive? I know there are a lot of blog posts out there saying that it’s all a conspiracy by big bad De Beers and jewelers who mark up diamonds 200%. I hate to break it to you but neither one of those things are true.
Why Diamond Certification Doesn’t Exist And Why That Matters
Everyone tells you the same thing. Don’t buy a diamond without a certificate. You definitely need a certified diamond. What does it say on the diamond cert? Does your diamond have GIA certification? What’s on the GIA cert? There’s just one problem with all that good advice. There is no such thing as diamond certification.
Why You Need a GIA Grading Report for Your Diamond
When you buy a house, it comes with a deed that details the measurements of your property. Your car has a title and registration. You also need documentation for your diamond engagement ring.
What are the Ideal Diamond Proportions?
Cut is the most important of the 4C's. The quality of a diamond’s cut is what makes it flash with brilliance, fire and scintillation and dance with light.

What Are D Color Diamonds?
When would you be happy to receive a D grade? When you’re grading the color of your diamond, of course! D is the highest colorless diamond grade and the ultimate colorless gem. D color diamonds are the pinnacles of icy colorless perfection. Why do we say colorless diamonds and not white diamonds? Colorless diamonds are transparent like water, not reflective like a white paint chip.
What Are E Color Diamonds?
Colorless, icy, and bright, E color diamonds are almost at the top of the standard diamond color scale. If you think of diamond color grades as a mountain, the pinnacle belongs to D-color diamonds, the rarest of the rare. E-color diamonds are also rare, also colorless, just, you know, not quite as much. You might think that means they are often overlooked. You would be wrong.

What Are I Color Diamonds?
Diamonds in the near-colorless part of the D-to-Z diamond color scale, are in the Goldilocks zone of diamond color: not too expensive like D, E & F colorless diamonds, but not noticeably off-white like K,L & M faint color diamonds. The value that near-colorless diamonds represent is just right.
What Are J Color Diamonds?
If you want a classic colorless white diamond, you probably are shopping in the near-colorless section of the standard D-to-Z diamond color grading scale. Near colorless diamonds have color grades of G, H, I and J.
What Are K Color Diamonds?
If you’ve been researching diamond quality online, you probably haven’t read many experts recommending K color diamonds. There’s a good reason for that. Because K-color is categorized as a diamond with faint color, it won’t be mistaken for a colorless diamond like a G or H color grade might.
What is a SI1 Diamond Clarity Grade?
We’ve certainly seen SI1 clarity diamonds that are beautifully eye clean. But we’ve also seen many that have inclusions you can see with your naked eye.

What is a SI2 Diamond Clarity Grade?
Here’s where it can start to get ugly. In general we don't believe that paying a premium for high diamond clarity grades is worth the trade-off. But we have to draw the line somewhere. And that line is generally in the middle of SI2 clarity.
What is a VS1 Diamond Clarity Grade?
The best Very Slightly Included diamonds, that is diamonds with a VS1 clarity grade, have a lot of fans. Why? They don't have any inclusions that you can see with the naked eye. And yet they are much more affordable than diamonds with an IF or VVS clarity grade.

What is a VVS2 Diamond Clarity Grade?
Inside every diamond are microscopic time capsules: crystals from the deep earth, tiny cleavages from the pressure, and atoms trapped with the diamond when it formed billions of years ago.
