Diamond Cut

Cut is often considered the most important of the four C’s because it determines the brilliance of the diamond. The more light reflected throughout the diamond, the greater the brilliance or sparkle.

At Solomon Brothers, we cut and polish our own diamonds to ensure greater quality. Our cutters use sophisticated computerized systems to measure the light-reflecting qualities of our stones and create superior brilliance.

Cut has three key components you should be aware of – Depth and Width, Symmetry, and Grade.

Depth And Width

If the cut is too shallow, light will leak out of the bottom of the diamond; too deep and light will reflect out of the side of the diamond. An “ideal cut” diamond is neither too shallow nor too deep, ensuring that no light will escape.

Symmetry

The symmetry of a diamond is defined by the alignment of its many facets (or surfaces) in relation to one another. An “ideal cut” diamond has all facets positioned in perfect geometric relation to the others, allowing light to bounce from facet to facet before returning through the top of the diamond back to your eyes.

Did You Know? A classic “round brilliant” cut includes a total of 58 perfectly aligned facets.

Grade

Leading gem laboratories such as the Gemological Institute of America (GIA) and the European Gemological Laboratory (EGL USA) grade diamonds according to the quality of their cut. They are graded on a scale from “poor” to “excellent”. Use the interactive scale below to further understand the differences in cut grades.

At Solomon Brothers, we use our state-of-the-art OGI Firetrace analyzer to ensure superior accuracy as we assess each diamond. This instrument gives us a sophisticated, computerized analysis that measures the diamond, mathematically simulates its light-reflecting properties, and determines how much “life” is in the stone. With our OGI Firetrace analysis, you know the exact properties of the diamond you are considering.

Excellent (Ideal)

An ideal diamond will display the maximum amount of reflected light. Because symmetry plays such an important role, only “round” diamonds (as opposed to specialty shapes) can be graded as “excellent”    ed-cut-excellent.cut

 

Very Good (Nearly “ideal”)

These diamonds reflect up to 90% of the light that enters them. They are exceptionally well-cut diamonds creating an exquisite stone. Good – Because these diamonds still reflect a good portion of the light that enters the stone, they make very attractive engagement rings.ed-cut-nearideal.cet

Good

Because these diamonds still reflect a good portion of the light that enters the stone, they make very attractive engagement rings.good.cut

Fair

These stones will reflect approximately 40% of the light that enters. While the size of the diamond can mean good value for money, the stone will lack high brilliance.fair.cut

Poor

Although less brilliant than other diamonds and therefore not recommended for engagement rings, these still create a lovely effect in earrings and pendants and often represent excellent value.poor.cut
