A Guide to Engagement Rings: Does Carat Size Really Matter?

November 10, 2016

Someone had to say it...The biggest diamond does not always win. Before you make an important investment we believe it’s necessary to answer the big question. Does carat size really matter?

Avoid making your decision solely based on carat weight. There are four criteria that make up quality. The quality of a diamond can be determined by the 4C’s: Cut, Clarity, Color, and Carat Weight. Take these pointers to help you in your diamond search!


Cut refers not just to the shape of the diamond, but to the angles, proportions and faceting arrangements of the stone. It is perhaps the most important of the 4cs because this determines how well the diamond reflects light. A well-cut diamond will internally reflect light from one facet to another and disperse and reflect it through the top of the stone.Types of Diamond Cuts

Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance. The shape of a diamond is its outline. Common shapes for a diamond are:

  • Round
  • Oval
  • Princess
  • Radiant
  • Pear
  • Marquise 
  • Heart 
  • Cushion

The faceting arrangement, along with the outline of the diamond, results in the diamond's visual brilliance. A diamond cut is classified as Excellent, Very good, Fair and Poor. At Fuller’s, we strive to present you with diamonds that are cut to maximize their intensity and brilliance.


Clarity is an indication of a diamond's purity. In all diamonds, except the most rare, tiny traces of non-crystallized carbon (the element from which a diamond is formed) can be trapped during the crystallization process. These internal 'inclusions' appear as tiny crystals, clouds or feathers. The presence of some inclusions does not diminish the diamond's beauty or endanger its durability. Most cannot be seen without powerful magnification.

Clarity is based on the quantity, size, position, nature, color and relief of inclusions in a diamond. There are 10 clarity grades, where each grade represents a range. Clarity is determined by a trained grader, using 10-power magnification.


Color refers to the degree to which a diamond is colorless. Color in a diamond is the result of traces of other elements, which mix with carbon during the diamond's formation. White diamonds are color graded on a scale that begins with “D” indicating a total colorlessness, progressing down the alphabet for lower qualities. While diamonds tinged with yellow or brown are less desirable. Diamonds of vivid colors such as Canary Yellow are rare and today are highly valued. With ArtCarved all of our diamonds are graded D through J, colorless and near colorless range.

Carat Weight

Carat weight is the gemologist's universal measurement of a diamond weight (not how big it is) and is the easiest of the 4cs to determine. Diamonds are weighed when they are loose or free from any mounting or setting. It is important to know that two diamonds of equal weight can have very different appearances because of their cut, and different values because quality is still determined by cut, color and clarity.
