Understanding Diamond Clarity
To evaluate diamond clarity, graders examine diamonds under 10x
magnification and determine the number, size, relief, nature, and position of inclusions and
whether they affect the overall appearance and durability of the diamond.
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.
Diamond Fluorescence and Value
Diamond fluorescence is one of the most controversial aspects of
diamond quality and value. It’s bad for diamonds. Except for when it’s good. It makes a diamond
worth less. Except for when it makes it worth more.
What is the Difference between Diamonds and
Diamond Simulants
When is a diamond not a real diamond? When it’s a diamond simulant!
These pretenders do their best to imitate the look of a diamond but are much less valuable. Some
do a much better job of simulating a diamond. Here’s what you need to know about the most common
diamond imitations.
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. Judging
the quality of a diamond’s cut is the most complicated of the 4Cs too. It requires evaluating
the way a diamond’s proportions, symmetry, and craftsmanship affect the way it sparkles.
Laser Drilled Diamonds (and Why You Should
Avoid Them)
Diamonds without eye-visible inclusions are rare. So it’s not
surprising that people have worked on ways to make diamonds with ugly inclusions look a little
better. The most common way to treat diamonds to improve their clarity is by using lasers.
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 F Color Diamonds?
F-color diamonds are in demand because they are colorless: the most
common (and most affordable) of the truly colorless diamond grades.
What Are G Color Diamonds?
G-color diamonds are in demand because they are colorless: the most
common (and most affordable) of the truly colorless diamond grades.
What Are H Color Diamonds?
If you have an unlimited budget, buying a diamond is easy: just get
a 15-carat D Flawless in your favorite shape. Done. For the rest of us, it’s a balancing act:
where do you compromise to get the best possible diamond for your budget?
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. And that’s
the dilemma of SI1 diamonds in a nutshell: sometimes they are a great value and sometimes they
are disappointing. That’s why we hesitate to recommend that you buy one.
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 VS2 Diamond Clarity Grade?
When you are buying a diamond, how much do inclusions matter? They
matter a lot if you can see them. But a lot of diamond clarity distinctions are completely
invisible to the naked eye.
What is a VVS1 Diamond Clarity Grade?
Diamonds are earth’s hardest substance: brilliant transparent
crystals that are close to perfect. So close to perfect, in fact, that the tiny imperfections
that distinguish them from one another are often so small that they can only be seen under
magnification.
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.
What is an IF Diamond Clarity Grade?
It’s not easy being a diamond. After forming deep within the earth
under tremendous heat and pressure and then riding a volcano of molten rock 100 miles up to the
earth’s surface, you are going to show your age. Especially when your age is a billion years or
so.
