Knowledge is power, and it certainly applies to the process of choosing a diamond. Good knowledge and research would help diminish the element of uncertainty in an expensive purchase.
Admittedly, sometimes there can be things that may be out of your control. For example, if you have a $3000 budget and are looking for an F color cushion, you might not be able to find a suitable diamond in stock and may have to settle for a G color diamond instead.
At the end of the day, you would need to explore your preferences and options by being clear on what you want. By doing your research at the forefront, it would enable you to make good decisions and avoid “after-sales remorse”.
Here’s a quick checklist to recap the steps to choosing a well-cut diamond (only applicable to round brilliant diamonds). It’s the quickest way to filter out poorly cut diamonds and narrow down your selections:
Weed out stones that fall outside the following criteria:
– Check for Table percentage to be within 54.0% – 57.0%
– Check for Depth percentage to be 61.0% – 62.5%.
– Check whether Pavilion Angle is within 40.6° – 41.0° range.
– Check whether Crown Angle is within 34.0° – 35.0° range.
– Filter down your choices to GIA Excellent Cut or AGS Ideal Cut.
Like I mentioned earlier, this is just a quick guideline to help you increase the probabilities of getting a great looking stone. On rare occasions, a diamond with a cut grade of Very Good can actually have better optical properties than another stone graded with Excellent or Ideal cut.
– Calculate the HCA score! Reject any stones with scores higher than 2.0.
– Verify the optical performance with Idealscope/ASET data.
This checklist is designed based on even more stringent cut proportion guidelines than those set by GIA & AGS.
With that said, regardless of whether you are buying online or in stores, I can assure you that you will end up with a beautiful diamond if all these criteria are checked.
Diamonds are significant purchases. Do take your time to read and do your own research. There is a wealth of knowledge that you can pick up from the articles on Beyond4cs.com.
