Diamond's Four Cs

How important is the cut of the diamond?


Cut and clarity determine a diamond’s brilliance and fire. 
Diamonds have inspired awe the world over for centuries, but buying one can be a little intimidating to some. There are vast differences in the quality and value of these popular gems that are not always obvious to the untrained eye.
It’s a good idea to understand other factors as well as the influences of cut and clarity before purchasing a diamond. Diamonds come in dozens of grades, and those grades rely on all 4 Cs:
  • Color
  • Cut
  • Clarity
  • Carat

Color and Carat

A colorless diamond is most valuable when compared with a tinted or hazy diamond.
A slightly yellowish diamond will cost a bit less. When the color reaches the other end of the spectrum, however deeper, darker and solid – the value rises again.
Those looking for the typical colorless diamond used in an engagement ring will want to choose one with a color rating of G, H, I or J.
An L will have a hint of yellow, although that will be less noticeable in a small diamond, or in a gold setting as opposed to a white gold or silver one.
Carat is the unit of weight. Price per carat goes up as the total weight of a diamond increases.
Carat is a more obvious factor to the general consumer than the other Cs are: It’s about weight and thus size. Most people choose quality over size. After all, it’s really about the sparkle.
Diamond Cut

 A diamond’s fire (“dispersion”) comes from its ability to take in white light and reflect it back as brilliant  flashes of color. Cut influences fire and helps determine how shimmering and beautiful a diamond will be.
The cut of a diamond is what facilitates its brilliance. Pavilion facets of a diamond become like mirrors,  and precise angles will establish how well those mirrors reflect light.
The best angle for a diamond pavilion facet is considered 41 degrees. Diamonds are natural though, and  nature does not always cooperate. Cutters can cheat a little bit on cut without sacrificing quality, but  reducing size too much will compromise the gem.
  •  Cut is most important in round diamonds under 2 carats in size. Clarity must be higher grade in larger  diamonds, or those in different shapes.
It’s not always easy to identify a compromised diamond when it’s standing on its own, but when compared to others without those flaws, the difference will be noticeable. This is why it’s important to compare several diamonds side by side.
Round diamonds make for the most brilliant jewels because their symmetrical proportions allow all angles to be cut the same way. Personal preference is an important consideration though. Other shapes include the marquis, princess, emerald, Asscher, radiant, oval, pear, heart and cushion.

Diamond Clarity

In smaller diamonds, especially those under 2 carats, clarity is not as easy to observe with the naked eye, and cut is most influential. In larger diamonds, clarity becomes more important. Diamonds in shapes other than round also require greater clarity.
The most attractive diamond will have balance between cut and clarity. Besides size and shape, clarity is determined by the number of inclusions it has. Inclusions can be mineral specks, fractures, tiny holes or any imperfection that interferes with transmission of light.
Strive for a clarity rating of at least SI1 or SI2. Sometimes a tough grader will assign an SI3 to a diamond with beautiful clarity. The highest clarity grade for a diamond is actually “flawless,” which means that no flaws can be found at 10 power magnification, under ideal conditions.
Clarity grades start with V (very), S (small) and I (inclusion) used in combination with each other and numerals (to indicate number of inclusions).
Remember, not all diamonds are considered gems. Industrial grade diamonds are used as abrasives, for instance. They might be cloudy, misshapen or full of inclusions. This is why carat is definitely least important. It has nothing to do with quality. Don’t fall for the lure of carat alone.
A diamond is an investment. Never be afraid to ask a jeweler about ratings, and take the time to compare your preferred gems with others, side by side. You want to feel good about such a significant purchase, and so you should.
