The 4Cs of Diamond Buying

The four C’s are the universal language for understanding diamond quality. It is important to remember that no two diamonds are alike. Each diamond speaks its own language and is translated through these four important characteristics.

  • Cut
  • Carat
  • Color
  • Clarity

The term “cut” has two references: One is the diamond’s shape, the other is the quality based on the proportions, symmetry and polish. This characteristic is considered the most important because it contributes greatly to the diamonds overall brilliance and beauty. The brilliance is the way in which the light reflects in and off the facets of the diamond. Unlike carat weight, color, and clarity, this factor is the result of human precision. Because the precision of the cut greatly affects the overall look, the price will fluctuate depending on the quality of the cut.


Carat weight is the most straight forward of the 4 C’s. A diamond’s weight is measured in carats. The carat weight of a diamond is subdivided into 100 equal parts called ‘points’. One point equals .01 carat or 1/100 carat.  A one carat diamond equals 100 points.  The carat weight is written in decimal numbers, but it is frequently expressed in fractions.

The price of a diamond increases with its carat weight. Larger diamonds are less common and therefore more desirable and fetch a higher price. No two diamonds are alike so even though the carat weight may match the other three factors may not which will impact the pricing.


Color choice is really a personal preference, although most people are usually looking for a stone with little to no color. The color evaluation on gem-quality diamonds is based on the absence of color. The Gemological Institute of America (GIA) uses a 12-letter alphabetical scale of D to Z. Using this scale, the diamond on the lower end of the scale (D) will have the least amount of color – it is considered a colorless stone. The diamond at the higher end of the scale (Z) has deeper tones.  However, when a diamond’s color is more intense than the “Z” grading, it enters the realm of a “Fancy Color” diamond. In this case, the intensity of the color in the diamond can play a significant role in its value. The value of a Fancy Colored Diamond can surpass that of colorless diamonds if the intensity of the color is high and the color is rare.


Clarity measures the amount of tiny imperfections or blemishes (inclusions) that are present within the stone. Because diamonds are naturally occurring, almost all diamonds have slight imperfections. It is rare to find completely flawless diamonds.  These imperfections are known as “inclusions” and usually occur during the diamond’s crystallization period within the earth, or from the stresses of mining and processing. Inclusions are anything from tiny white points to dark dots, cracks or scratches. The fewer inclusions, the more valuable a stone is. Clarity is evaluated using a 10-power magnification. This means that the object viewed appears 10 times its actual size. The diamond grader examines the clarity characteristics with respect to the nature and number of characteristics, as well as their size, color and position. The clarity grade assigned reflects the degree of visibility of the characteristics.

The GIA Diamond Clarity Grade scale has five main categories of clarity characteristics with 11 grades in all.

  • The FL Grade (Flawless) The term FL or flawless is used for diamonds in which a qualified observer, under favorable lighting conditions, cannot find internal characteristics and/or faults by thorough examination with a 10X loupe.
  • The IF Grade (Internally Flawless) A diamond which has no internal characteristics but which, due to minor finish faults, is not flawless and therefore cannot be designated FL or flawless, may be called IF or internally flawless provided the finish faults are so minute that they can be removed by a gentle polishing with only an insignificant loss of weight.
  • The VVS Grades (Very, Very Small Inclusions) The term VVS is used for diamonds with internal characteristics very, very difficult for a qualified observer to find under observation conditions as described. Further, there may only be insignificant finish faults.
  • The VS Grades (Very Small Inclusions) The term VS is used for diamonds in which it is difficult for a qualified observer, under observation conditions as described, to find either a few somewhat larger internal characteristics or several very small ones.
  • The SI Grades (Small Inclusions) The term SI is used for diamonds in which a qualified observer may, without difficulty, under observation conditions as described, find internal characteristics. Further, there may only occur single finish faults of an insignificant kind.
  • The I Grades (Imperfect) The term I or imperfect is used for diamonds in which a qualified observer, with the naked eye, can see internal characteristics and/or in which such major faults occur, which substantially reduce the value of the stone.

Only about 2% of the world’s diamonds are actually flawless. Most retail stores carry VVS as their highest grade. VS or SI are considered by most to be “fine quality” diamonds.

Wearing Jewelry

Jewelry is a beautiful and often sentimental accessory. We know that sometimes it is difficult to part with your treasure but there are certain times, in order to preserve its look, it should be removed to avoid any damage or unnecessary wear and tear.

  • Remove Jewelry during Manual Tasks– This will prevent physical damage or harsh exposure to household cleaning solutions.
  • Put Jewelry on After Applying Makeup or Hairspray– Avoid wearing jewelry during your morning routine. Cosmetics, hairspray, lotion and perfumes contain material that can damage or dirty your jewelry unnecessarily.
  • Do Not Wear Jewelry While Swimming or in Spas– Chlorinated water can react with metals found in jewelry which can cause changes in color or expedited tarnishing.
  • Remove Jewelry before Playing Contact Sports– Wearing your jewelry during sports can damage the jewelry itself as well as the wearer. Remove all jewelry before engaging in competition.
Cleaning Jewelry

For those that wear jewelry regularly, keeping their jewelry clean and looking good requires regular effort. Here are some general guidelines that may help:

  • Use Jewelry Polishing Cloths for Best Results– Polish silver or gold with a jewelry polishing cloth for best results.
  • Clean Your Jewelry With Care – It is important to be delicate with your jewelry at all time but especially when cleaning. Because it is such a hands-on process, pay close attention and care. There are commercial products that can be purchased or if you have a trusted jeweler in the neighborhood, it may be best to bring it there.
  • Use Warm Water to Clean Jewelry– Using warm water is the best bet when cleaning your own jewelry.
  • Inspect Your Jewelry Regularly- It is a good idea to inspect your own jewelry for any damage. If it is a favorite piece and worn often, you should consider bringing it in to a trusted jeweler every six months for inspection.

Throughout the lifetime of your jewelry, it may be necessary to make a repair or refurbish. We recommend you return it to IBGoodman for repair or refurbish.  In that case contact IBGoodman, tell us the nature of the service you require and we will explain how the process for returning your jewelry for repair/refurbish.  Upon inspecting your jewelry, we will provide you a cost quotation for the work.
