The Four C’s – Cut
The cut rating of a diamond is the best guide to the overall beauty of the gem. A diamond may have the best color rating (colorless), clarity rating (Flawless) and large Carat weight but, if poorly cut, will merely be very expensive, while still very ugly.
As most jewelry is viewed from the top, this other C… Cut, which is comprised of proportion, symmetry, polish, and shape…plays an important role in the appearance of its carat weight. In other words, does your one carat diamond look like a one carat diamond? It may actually look smaller than a properly cut one carat stone. (Which means you paid for the weight and didn’t get the look.) A poorly proportioned, one carat diamond, even though it may have a large surface area, may not look as large as its carat weight suggests. For example, an improper cut could result in a “thick” diamond, (meaning it is too deep when considered from the top of the stone – table, to the pointy end – or culet), and will appear smaller compared to a properly cut stone of equal carat weight. You might also have a diamond that is cut too shallow as well. Both will suffer from a lack of brilliance (reflected white light) and fire (refracted colors) as well as scintillation (sparkly) because of their deviations from the combination of “sweet spot” proportions compared to an Ideal or Premium cut diamond as discussed in “Cut”.
Shape outline and facet pattern are two of the other of the five components that contribute to the effect of cut. Generally, round and square outlines are more symmetrical, (can be folded in half more times), and consequently more reflective than marquise, hearts, pears or emerald cuts. But any shape outline will look its best when fashioned to the most pleasing proportion, surface polish, and facet symmetry. The hard part is determining how to evaluate “What is best?” That’s where Palmetto Gems can help.
