When choosing which diamonds to buy it is important to know the cut of the diamond that is desired. The shape of a diamond is often confused with the diamond cut. The most typical shape of a diamond is round brilliant, but there are several other variations like oval, marquise, pear, heart, and emerald.



Other things that go into the quality of the diamond cut are the height of the crown, the depth of the pavilion, the width of the table and the quality of the symmetry. These aspects of a diamond cut are much more detailed and should not even be considered unless you are interested in very high end diamonds. 

Of the 4 C's, the diamond's cut is the most important factor in determining its brilliance and beauty. Sometimes a diamonds cut is confused with a diamonds shape. This is likely due to some in the industry mistakenly referring to a diamond being a 'round' or 'princess' cut. When speaking of a diamonds 'cut grade', we are referring to its proportions, symmetry and polish. Thediamondstore.biz will not sell diamonds with a cut grade considered less than very good.

Ideally, the cut of the diamond is done in a way to best reflect the light that shines into it. This is what produces the sparkle and fire we see in a beautifully cut diamond. If the diamond is cut too heavy, or too shallow, most of the light entering into the crown is released through the bottom of the pavilion resulting in an overall dull appearance. An ideal cut diamond on the other hand, returns most of the light that enters it back through the crown giving it a very satisfying sparkle effect.

Nature determines so much about a diamond, but it takes a master cutter to reveal the stone’s true brilliance, fire and ultimate beauty.

Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing well-cut diamonds higher on the Diamond Quality Pyramid than deep or shallow-cut diamonds. Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance and ultimately, value.
