Decoding Diamonds: Cut

If you’ve just started searching for engagement rings, you might be overwhelmed by the 4 Cs.  The Gemological Institute of America (GIA) developed the 4 Cs as a guideline to help you easily decode diamonds.  So why does it seem like you’re learning Ancient Greek?  In our four part series, we’ll break down everything you need to know about your sparkler.

Of the 4 Cs – Cut, Color, Clarity, and Carat – cut tends to be the first big diamond decision. First and foremost, cut refers to the shape of your stone. With ten varied diamond shapes, there’s a cut for everyone. Are you an elegant sophisticate who loves the clean lines of the emerald cut? Or do you love feminine grace, making the pear shape your pick? No matter your style, there’s a diamond shape for you.

Beyond just shape, cut refers to the quality of the stone’s cut.  Are the facets symmetrical and even?  How carefully did the diamond cutter balance proportions?  Every angle can make a huge impact on your stone’s brilliance.  If the stone is too deep or too shallow, it might not look as lively as one with harmonious proportions.  GIA grades the quality of a cut with ratings from poor to excellent.

GIA’s grading can be a key part of the stone selection process.  Regardless of a stone’s grades and measurements, don’t be afraid to trust your gut and pick the stone that you and your hubby-to-be love the most.
