Questions about Diamonds

What are the 4 C’s?

The 4C’s represent a diamond’s quality, both in beauty and structure. They stand for Cut, Color, Clarity and Carat. The 4C’s are how gemologists grade diamonds, which then allows the market to effectively price them. 

What is Cut

Cut refers to how well a diamond’s facets react to light. The grading is fair/poor, good, very good, and excellent/ideal.

What is Color?

Color refers to the color of a diamond, or the lack thereof. Many white diamonds have a soft hue of yellow or brown. The best grade would be a diamond that is completely white, as shades of yellow/brown cause visual distractions that affect sparkle. These nuances in color results in a large difference in price. The grading ranges from D to Z, with D being the highest grade, as it is completely colorless.

What is Clarity

Clarity refers to impurities or imperfections within or on the diamond. These are known as diamond inclusions. Inclusions are like a birthmark of a diamond. Inclusions are examined at 10x magnification, as many times they can’t be seen by the naked eye. Needless to say, a diamond with no or fewer inclusions is of a higher grade. Clarity grade ranges from IF to I2, with IF being the highest. IF stands for internally flawless, it is a perfect diamond inside and out. Of course, these are extremely rare. As natural diamonds will almost always have inclusions, most people consider VVS diamonds to be the best as IF’s are so rare. VVS stands for “very, very slightly included”.

What is Carat Weight?

Carat refers to the size of the diamond in carat weight. A metric “carat” equals to 200 milligrams. To do the math, it is simple, yet perfectly precise. You take a diamond and weigh it in grams then divide it by 0.2. So, if a diamond weighs 0.4 grams, you divide by 0.2 and you get 2 – 2 carats. Now, in terms of grading, there is no grading for this as a diamond can weigh any amount, reasonably speaking. The largest diamond found in the world was 3,106.75 carats (rough, meaning uncut diamond). That being said, the majority of diamonds in the jewelry market range from .25 carats to 5 carats. When it comes to calculating a diamond’s price by carat weight, it is not as simple as four .25 carat diamonds are the same price as a 1 carat diamond. As bigger diamonds are rarer, they will cost more. Moreover, the other aspects of the 4C’s come into play with every diamond.

Note: The above 4C’s apply to Round Brilliant Diamonds. Other diamond shapes will have a slightly different grading system. The Cut will be looked at in terms of Polish and Symmetry instead. The rest of the 4C’s will apply.

What are the different diamond shapes?

There are various shapes of diamonds. You have round, cushion, princess, oval, pear, marquise, emerald, radiant, Asscher, heart, baguette, and more. Anything other than a round diamond is considered a “fancy shape diamond”.

What is the “5th C” of a diamond? Isn’t this a thing?

The 5th C can mean a few things…

Certification, Conflict-Free or Confidence

Typically, the 5th C refers to a diamond certification, from a reputable gemological institute. GIA is the most famous and reputable of them all. The certification has all of the 4C’s grading on it. It will tell you all you need to know about the diamond in question. 

When buying diamond jewelry with large diamonds, a diamond certificate is very important as it gives you peace of mind and confidence, as you know exactly what you are getting. 

diamond jewelry questions

Should the diamonds in my jewelry be certified?

This depends on the price of the piece in question and the size of the diamonds. For negligibly priced jewelry and jewelry with small pave diamonds, it is not necessary. In this case, you will simply want to buy from a jewelry store that you can trust. 

However, if you are buying diamond jewelry with a large diamond, you will want a diamond certification. This will give you more confidence when buying something very expensive.

As for engagement rings, it is almost always recommended that the diamond has a certification.

Does a diamond need a certificate

What is the most important of the 4C’s of diamonds? 

The most important aspect of the 4C’s is said to be the cut. The brilliance and fire of your diamond depend most on the cut. A perfectly cut stone will allow you to make some comprises on the other factors of the 4C’s, while still having a great diamond that sparkles and pops. 

You don’t need a perfectly colorless D-grade diamond as it is almost impossible to spot the hue of yellow on an E-H diamond with the naked eye. The same thing applies to inclusions. Even inclusions on an SI1 diamond are often impossible to see with the naked eye. Check the diamond in good lighting to make sure these flaws can’t be seen with the naked eye and focus on the cut!

diamond questions

How to get the best diamond for your budget?

We have a few tips:

  1. Consider fancy diamond shapes, as Round Brilliant diamonds are the most expensive.
  2. Halos offer more size without needing to buy a large diamond. Again, many small diamonds are far less expensive than one big one.
  3. Focus on cut and sacrifice the other 4C’s a bit. Get a lower grade that is still beautiful to the naked eye.
  4. Buy a diamond that is just under 1 carat or just under 2 carats. As once they reach those margins, the price jumps significantly. Again, the bigger the diamond, the rarer it is, and the more expensive it is. 

Are synthetic diamonds as good as natural?

Although synthetic diamonds have the same exact physical properties as natural diamonds, they are not valued the same. Not even close. Synthetic diamonds will be much less expensive than natural diamonds, and they will have basically no value after you buy it.

But are they as good? In fact, they are often better in terms of the 4C’s, as can be made with zero inclusions and perfectly white.

So, if you are dealing with a “natural” diamond that is perfect, you will definitely want to check that diamond certificate.

Note: There are some very expensive machines that will tell you if a diamond is natural or lab grown. So gemological institutes know! Diamonds By Raymond Lee in Boca Raton has one of these innovative machines to spot if a diamond is real as we buy jewelry from the public. Any high-end jewelry store should have one of these nowadays.

Is buying used diamond jewelry good?

People often consider used jewelry as “low quality”. That is false. The only thing different from used and new is that someone owned it before you! Fine diamond jewelry is not like a car or shoes that wears down and loses value, the materials are everlasting. A simply polishing and it will look brand new. Moreover, new jewelry is only new until you buy it!

Advantages of buying used diamond jewelry:

  • Better price and best bang for your buck. 
  • You retain more value, as the initial buyer took the hit that comes with buying jewelry new.
  • More options and styles to choose from. 

So, to answer this question, yes used jewelry is good. It is also smart if you want to get something beautiful for a good price. It is only bad if you don’t like the fact that someone has worn it before you.
