THE 4 C'S OF DIAMOND GRADING!
THE 4 C'S OF DIAMOND GRADING!
THE 4 C'S DIAMOND CHART, COLOR, CLARITY, CUT & CARAT WEIGHT!
When Jewelers refer to the 4 C's of Diamonds, they are referring to 4 main characteristics that help Identify, Classify, and Price Diamonds (Loose or Mounted).These 4 main characteristics of the 4 C's are:The Cut of the Diamond.
LEARN ABOUT DIAMOND CUT!
EXPLAINING DIAMOND CUT OF THE 4C'S GRADING SYSTEM!
Out of all the 4C's to explain, Cut is not only the hardest, but the most confusing and complex subjectknown to Diamonds and Diamond Quality!Cut can mean so many different things to so many different people. And this vague and complicated issue is what allows many Jewelers to pull the wool over your eyes and to sell you low quality Diamonds for good amounts of money.
You see, to most consumers, Cut means very little. Most people just believe that Cut means nothing more than the Shape of the Diamond! And for good reason to. When we refer to Diamond Shapes, we actually call them Cut. Like Brilliant Cut, Marquise Cut, Princess Cut or Trilliant Cut(Which is Triangular - Not shown on the diagram). Even Baguettes are called Baguette Cut Diamonds! So with Jewelers calling the "Shape" of the Diamond "Cut", it's actually very easy to understand why some people would get confused. No doubt most people just disregard Cut as nothing more than...
But Cut is so much more than that! Cut is really meant to talk about the Proportions and Finish of the stone. The Symmetry and Angles of the Facets. Cut is all about Culet Size andGirdle Thickness and Surface Polishing. It's so much more that the actual Shape of the Diamond.

If you look at a Certified Diamond Report, you'll see that the other 3 C's (Color, Clarity & Carat Weight) just take up a couple of lines on the Report. Where as Cut, Cut takes up Ten lines. It covers a lot of ground. And it includes some very intricate details that can make or break a Diamonds beauty and appeal.
Cut is actually so important to the 4C's, that Cut alone, can be the biggest difference in great brilliance, sparkle and price of a Diamond.
My advice: Do not disregard Cut as something non-meaningful.
Study Cut. Learn what an Ideal Cut Diamond is. It could be the difference in getting a great Diamond and a great deal, to getting ripped off and purchasing an ugly Diamond with no sparkle! Cut is major!

LEARN ABOUT DIAMOND CLARITY!
DIAMOND CLARITY OF THE 4 C'S EXPLAINED!
Microscoping
Clarity in Diamonds is basically the amount of imperfections or flaws in a Diamond. Those flaws can be inside the Diamond, or outside the Diamond, (on the outer surface) where they are normally called blemishes!
Imperfections, Flaws, Blemishes, Inclusions, and Defects in Diamonds can be called many different things. Namely: Crystals, Pin Points, Cracks, Breaks, Fractures, Feathers, Cleavage Lines, Bearding, Clouds, Growth Lines, Grain Lines, Cavities, Laser Drill Holes, Knots, Scratches, Nicks, Pits, Abrasions, Extra Facets, Naturals, and Trigons! Whew! And you thought they were just called Inclusions!
A Closer Look
Crystals
Pin Points
Cracks
The big deal with cracks is: The Smaller = The Better! Large cracks can weaken the Diamond and cause it to break in half with any accidental blow. Also note that if the crack actually breaks the surface of the Diamond, then it's not only more noticeable to the eye, but it's also more fragile! Be careful with cracks!
The Color of the Diamond
LEARN ABOUT DIAMOND COLOR!
EXPLAINING DIAMOND COLOR IN THE 4C'S OF DIAMOND GRADING!
When most customers look at Diamonds, they tend to believe that Diamonds are all the same color. It's true! Most don't notice the color differences in them until a Jeweler points it out.Most Diamonds have Color
You see, Diamonds are graded with the alphabet letters D-Z. (There is no A, B or C) D-Z is the Diamond Grading System Chart as devised by G.I.A. (The Gemological Institute of America!) who developed the 4 C's!
The actual Color ranges are broken down into 5 main categories.
Color Grades
G-H-I-J, which is the Near Colorless color range.
K-L-M, which is the Faint Yellow color range.
N-O-P-Q-R, which is the Very Light Yellow color range.
S-T-U-V-W-X-Y-Z, which is the Light Yellow color range.
(And also Z+, called Fancy Color, which is every color range beyond the alphabet letter Z!)
Z, on the other hand, is the lowest Color range there is. Z is a dark Yellow color that's not preferred and doesn't sell!
Fancy Colors
A Diamond that's a real, true Fancy Canary Yellow Diamond, or a Pink (the rarest color) orBlue Fancy Colored Diamond can truly be 100 times the price of a Pure White Diamond. They're that rare! See... Not all Color in a Diamond is bad!
But sadly, Fancy Color Diamonds are not only very rare, but very expensive. What we are left with instead, are Diamonds with faint colors of Yellow, Brown (Champagne Colored orChocolate Diamonds), and Gray Colored Diamonds. Those are not so nice, and crazy enough, the market is flooded with them.
The Carat Weight of the Diamond.
DIAMOND CARAT WEIGHT!
DIAMOND CARAT WEIGHT OF THE 4C'S EXPLAINED!
And of course, when I'm talking about "sense", I'm not talking about sense, I'm actually talking about "cents"! Big difference!
Think about Money
So then, a Half Carat Diamond, (1/2 ct) is .50 Points! See how easy that is?
A 1/4 Carat Diamond is .25 Points. A 3/4 Carat Diamond is .75 Points. Are you getting my drift? It really is that simple. Just compare it to Dollars and Cents!
How did the Carat Weight start?
So what is the Best selling Carat Weight? Read on...
